Introducing hands-on tutorials during the course of advanced physical chemistry has been demonstrated as an effective method to help the students understand the bridge between theory and experiment. With the aid of computer visualization, abstract concepts were vividly illustrated, which was hard to achieve experimentally. In this course, we started from the principles of quantum mechanics and molecular mechanics, and designed seven hands-on tutorials, including the calculations of molecular spectroscopy, chemical reaction path and microscopic heterogeneity of solutions. Such visualization-based teaching has helped students to understand the physical concepts from electron and molecular level, which in turn improved their ability to apply theory and computational tools for practical applications.

Organic chemistry is the major course of chemistry and other related disciplines. It is difficult for students to learn organic chemistry well, because of the abundant and complexed contents. With the purpose to help the students to learn organic chemistry well, we assigned the contents of organic chemistry with a number 12410100150, which is just like a mobile phone number. "1" represents a learning objective; "2" represents two hands; "4" represents four kinds of spectroscopy; "10" represents basic theories; "100" represents the different types of reaction mechanism; "150" represents different types of reactions. After several years' of practice, we found that students could remember the meaning and contents of this "mobile phone number" and learn organic chemistry much more effectively.

Based on the definition of "the same elements of the different forms of pure elements called allotrope", a large number of allotropes of carbon, which can be divided into graphites, diamonds, fullerene carbon clusters and new nanomaterials, were summarized in this paper. Meanwhile, this paper briefly describes the existence, composition and structure, preparation and properties of various allotropes, and emphasizes the forecast of computational chemistry on the allotropes and the role of modern scientific and technological development in preparation and its application in materials.

In this paper, the synthesis and characterization of salicylaldehyde Schiff-base compounds with aggregation-induced emission(AIE) character were introduced. Students will grasp the methods for the synthesis of Schiff-base compounds, the principle of fluorescence and the difference between AIE and aggregation-caused quenching (ACQ).Also, students will learn about the structure and design strategy of AIE molecules through class and network learning.

This paper reported our innovative design on the experiment of chromium(Ⅱ) acetate hydrate preparation through extensive exploration and practice. This new design was that the Cr(Ⅱ) solution was poured into sodium acetate solution in a hydrogen atmosphere.Compared with the traditional preparation method, the new design is simple and easy to operate, and the purity and yield of the product is high, which is a more suitable way for students' experiment.

An organic chemistry experiment was recommended, which is suitable for the students of chemistry & chemical engineering majors. In the presence of sodium nitrite and hydrochloric acid, phenyl diazonium salt was synthesized by diazotization reaction of aniline. Then, 1-phenyltriazene was afforded via the coupling reaction of phenyl diazonium salt with tetrahydropyrrole. The experiment involves the experimental operation including low temperature reaction, recrystallization, melting point determination, as well as NMR and IR spectroscopies for structural identification of the compound. The reaction mechanism includes diazotization and coupling reaction. The experiment has the advantages of inexpensive raw materials, high product yield, short reaction time and easy operation. The experiment is helpful for cultivating and improving students' practical and innovative abilities.

Aiming at the problem that the waste sodium of the laboratory is difficult to deal with, this paper presented a method to eliminate the waste sodium. Kerosene and water were added in the reactor to form two-phase states of oil and water, and then the sodium blocks were put into the reactor. Due to the action of the gravity, the buoyancy of kerosene and the product of the reaction, the sodium moved between the oil layer and the oil water interface, and gradually reacted with the water. This method is safe and simple.

Based on students' professional ability development and the students' experiment ability, innovation ability and teaching ability are not roundly trained in chemistry didactics experiment courses, the implementation of teaching reform research is needed. Through developing complicated experiment research design and experiment teaching activities, we could promote students' teaching research consciousness and ability, and improve students' professional ability in practice.

In order to help students understand the structure features of organic compounds displayed in two-dimensional space of theoretical classrooms, we offered a three-dimensional experimental classroom of organic molecular model construction. Students participated in the construction of organic molecule models by themselves with the questions about the relationship between molecular structures and property, and then they answered these questions combining theory knowledge.The problem-based learning (PBL) mode could not only help students to understand and master the spatial structure of organic molecules and the relationship between structure and property, but also help them to strengthen the practical ability and space imagination ability.The experiment report and the questionnaire survey suggested that the majority of students approve and accept the new teaching method, and the teaching effect was very good.

Construction of curriculum group for bio-pharmaceutical specialty, including integration of curricular content, teaching process optimization, experiment teaching management, and the application of network platform, was introduced.Through migration and dispersion, pruning and merging, the curricular content was reorganized, and thus the link chain of inorganic-organic-bio-analytical-pharmaceutical chemistry was established.Based on the systematicness and applicability of relevant knowledge,serial special teaching subjects were set up to motivate undergraduate learning initiative.With elaboration of courseware by teaching team,and then integration of the traditional chalk education with modern teaching mode, the efficient classroom was attained.Experimental projects were modularized while the basic ones were designed as micro-lesson, in which the instructional materials were available on the website of experimental teaching center. Furthermore, the "Vanya" online open courses were also developed.Consequently, the accomplishment of chemistry curriculum group led to the coordinated development and synergism of chemistry curriculum, and hence achieved optimization of the teaching process.

The professional English course for postgraduate students from chemistry and chemical engineering exists several problems such as its poor practical applicability. Therefore, in order to improve the students' communication skills, it is necessary to learn the advanced teaching and management mode from abroad during the curriculum reform. In this paper, general requirements for professional English course of science and engineering majors in National University of Singapore were introduced. In addition, the teaching management mode was also discussed from the perspective of course organization, content, teaching mode and feedback. Finally, suggestions were given to the domestic professional English course teaching.

A study of orientation effect of the phenyl(RPh) on the electrophilic aromatic substitution in the biphenyls (RPh-Ph,R:NH₂,CH₃,OH,Br,H,CHO,CN,COOH,NO₂) was carried out by the G03 packages software at HF/6 -31G basis set level, respectively. The conformational analysis of the biphenyl and substituted biphenyls showed that the rotational barrier about the carbon-carbon bond in biphenyl and m, p-substituted biphenyls is tiny, the rotation energy barrier (△E) is ca. 12 kJ/mol, the rotational barrier △E_(R) in o-substituted biphenyl is larger than biphenyl and m, p-substituted biphenyls, △E_(COOH) > △E_(NO2) > △E_(CHO) > △E_(CH3) > △E_(NH2) > △E_(OH) > △E_(Br) > △E_(CN), as a result, their rotation about the carbon-carbon bond is sterically hindered. The atomic charge distribution of the biphenyl and substituted biphenyls with the conformational is change. The minimum energy structure of biphenyls in same compound, whether this substituent group (R) is the class Ⅰ or the class Ⅱ positioning group, it is larger total charge density on the unsubstituted benzene ring of carbon atoms than substituted benzene ring, the electrophilic substitution reaction, therefore, introduction of a second substituent usually selective takes place in the unsubstituted benzene ring.Due to the charge density of o-carbon atoms of unsubstituted benzene is relatively small, and stereo effect is larger, and the charge density of p-carbon atoms is larger, introduction of a second substituent usually selective takes place in the unsubstituted benzene ring in the p-position.Therefore, substituted phenyl (RPh) is p-positioning group in the biphenyls.
