摘要：

The aim of this study is to establish the structure-properties relationship of tetrathiafulvalene (TTF). After this study (1) TTF crystals with alpha and beta phases were controllably obtained by the cast method with careful selection of the solvents, and (2) organic field-effect transistors (OFETs) of alpha and beta phases both exhibited field-effect performance, and the performance of alpha phase was much better than that of beta phase. The highest mobility of alpha phase reached 1.2 cm(2) V-1 s(-1), while beta phase showed the maximum mobility only about 0.23 cm(2) V-1 s(-1), indicating the strong performance dependence of OFETs performance on the crystal phases.
