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.

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