Three Tetrathiafulvalene (TTF)-assembled thiophene molecules were synthesized with the different linkages of s bridge via Steglich esterification and classical SN2 reaction. The results of UV and CV showed the different substitution effects existed in the new molecules formed by the molecule assembling. Among the new molecules, TTF-Th-2 (TTF-methylene-thiophene), linkage in the shortest s bridge, exhibited the most obvious substitution effects. Meanwhile, the result of theoretical calculation indicated that TTF-Th-2 exhibited lower bandgap with the evident electron transfer in the LUMO energy level.

A novel compound based on catalytic functional metal rhenium, pyridinium perrhenate(PyHReO4) was synthesized and characterized. The pyridinium perrhenate was used as catalyst in twotypes of reactions. One is the epoxidation of cyclooctene, the other is the Baeyer-Villiger oxidation of cyclicketones to lactones. The effects of catalyst, oxidant, solvent, reaction time and temperature were investigated,which confirmed the optimum reaction conditions of the catalyst system. Both types of catalytic reactionsexhibit high yields and high selectivity.
The synthesized novel compound based on catalytic functional metal rhenium, pyridinium perrhenate(PyHReO4) exhibit excellent catalytic activity. The system with PyHReO4 as a catalyst provided an effective, easy separation, mild and convenient method in two different types of reactions(One is the epoxidation of cyclooctene, the other is the Baeyer-Villiger oxidation of 2-adamantanone).
