Synthesis and Functionalization of Novel Tetrathia[7]helicenes as New Push-Pull Systems

Abstract

The synthesis of new functionalized 1,2-bis(benzodithienyl)ethenes as well as the preparation of the new tetrathia[7]helicenes are described. The helicenes reported are new chiral push-pull molecules, with potential application in optoelectronics.

Key words

benzodithienylethenes - helical structure - push-pull heterohelicenes - tetrathia[7]helicenes - acylations

We are currently studying this possibility by introducing phosphine groups on the helical system.
