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
