Synthesis and functionalization of novel tetrathia[7]helicenes as new push-pull systems / E. Licandro, C. Rigamonti, M.T. Ticozzelli, M. Monteforte, C. Baldoli, C. Giannini, S. Maiorana. - In: SYNTHESIS. - ISSN 0039-7881. - 2006:21(2006), pp. 3670-3678.
Abstract:
The synthesis of functionalized 1,2-bis(benzodithienyl)ethenes and the prepn. of the corresponding tetrathia[7]helicenes are described. The helicenes reported are chiral push-pull mols., with potential application in optoelectronics. Functionalized tetrathia[7]helicenes are obtained in good yields by application of two different synthetic strategies: (1) introduction of functionalized groups onto the alkene precursor followed by photochem. cyclization or (2) direct functionalization of the helicene.
