Thienoacenes are a representative class of high mobility organic semiconductor materials (OSCs). Asymmetric molecules based on them tend to form a bilayer arrangement in thin films and grow in a twodimensional layer-like manner, which has the advantage of achieving high mobility. The length of the alkyl substituents affects the packing microstructure of OSCs. Herein, thieno [4, 5-b] [1] benzothieno [3, 2-b] [1] benzothiophenes substituted with different lengths of alkyl chains (syn-BTBTT-Cn, n=4, 5, 6, 7, 8, 10) are designed and synthesized to systematically investigate the effects of lengths of alkyl chains on their thermal stability, energy levels, charge carrier transport capabilities, packing structures and film morphologies. All compounds are thermally stable and do not have liquid crystalline behaviors. All molecules in the vacuumdeposited films form a bilayer arrangement, within the conjugated cores forming a herringbone packing motif, and the alkyl chain length affects the film order and the tightness of the packing. Organic thin. film transistors devices all exhibit mobilities beyond 7. 0 cm² (/ V·s). Among them, the syn-BTBTT-C8 devices show a mobility of up to 13. 8 cm² (/ V·s) with the average values of 12. 5 cm² (/ V·s). [ABSTRACT FROM AUTHOR]

Experimental teaching of natural medicinal chemistry is an important specialized basic course of pharmacy. In the few past years, natural drugs are getting more and more attraction and popularity worldwide. With the proposed strategy for the modernization of traditional Chinese medicine, cultivation of innovative talents of pharmacy is urgently request for our country, thus the importance of experimental teaching of natural medicinal chemistry is increasing day by day. In this article, based on the characteristics of the course and experiences of our teaching practice, the related problems occurred in teaching process as well as the exploration and cogitation for the course reformation were summarized with the purpose of adapting to the development of the academic subject, as well as to improve the teaching efficacy of natural medicinal chemistry experiments. The proposed ways and measures (eg. improve the curriculum design, teaching plan, curriculum contents and exam standards) could thus promote the teaching effectiveness and quality of the experimental teaching of natural medicinal chemistry.
