: Since 2009 when Sichuan University started to implement the Top-notch Undergraduate Training Program (Top-notch Program for short) in Chemistry, a relatively comprehensive scheme of international training has been established and progress has been made. As the Ministry of Education starts the “Top-notch Undergraduate Training Program 2.0” in 2019, we are obliged to review the current international training model for chemistry undergraduates by learning from other universities both domestic and overseas to explore better ways of deepening international cooperation and improving the quality of international training for top chemistry students.

: In this paper, a simple thermodynamic model of crystal macroscopic morphology and the cause of the defects were suggested. By virtue of growing alum(K) crystals and measuring their macroscopic parameters in the inorganic laboratory for undergraduates, we can calculate the thermodynamic parameters of alum, thus explaining the macroscopic morphology and defect of alum(K), and predicting the possibility for alum(K) to generate octahedral crystals and its self-normality.

: In order to effectively enhance students’ interest and enthusiasm in learning buffer solution, a case of introducing real daily necessities into laboratory teaching is recommended. The experimental design extends the property test to the baby wipe, and changes the content of the experiment into the verification of the working principle of wipe, instead of preparation of simple acid-base system and related verification experiments in the past. Through the implementation of this experiment, students generally reflected that it can effectively stimulate their enthusiasm and interest in learning buffer solution related contents, and ultimately promote them to recognize the characteristics and buffer mechanism of pH changes in buffer system.

: In this paper, a new experiment named “synthesis and characterization of a fluorescent molecule based on Schiff-base” is introduced. It contains the synthesis and characterization of organic compounds, the determination of fluorescence, and the detection of metal ions. This experiment is helpful for students to better understand inorganic chemistry, organic chemistry and analytical chemistry. Moreover, it gives students an opportunity to know the study of organic fluorescent probes. This will stimulate students’ interest in scientific research and cultivate their research ability. Thus, this experiment can be introduced to senior undergraduates.

: Under the catalytic conditions of tetrahydropyrrole, an addition-elimination reaction of chromone aldehyde with methylpyrazolone or 2-indolinone is carried out to obtain two kinds of chromene derivatives containing pyrazolone or indol-2-one. The structures are identified by 1 H NMR, 13 C NMR, HPLC, HRMS and melting point measurements.
