Abstract

Cyclooctatetrathiophene (COTh) shows a novel saddle-shaped molecular structure, which has been applied in organic synthesis and material science. In this paper, the design and synthesis of COThs and their derivatives were described. The derivatives of COThs include mainly four types. One is isomer with different sequences of the four thiophene rings; the second is oligomer such as dimmer and dendrimer; the third is derivative functionalized by substituent groups at the four α positions; the last is the one planarized by sulfur, silicon or sulfone bridges. The applications of COThs and their derivatives in molecular muscles and field effect transistors were also discussed.
