Photoswitched sexithiophenes: Towards switchable molecular wires



A photoswitchable molecular wire based on a sexithiophene core is described that has potential as a light-driven molecular switch. The synthesis route. UV-vis spectra, and electrochemical behavior are presented for the compound, which behaves like substituted terthiophene in the open form and like substituted sexithiophene in the closed form. It is shown that interconversion between the open and closed forms can be achived using two different wavelengths of the visible region; applications are foreseen in organic electronic devices.
