Structural control of the electronic properties of photodynamic azobenzene-derivatized π-conjugated oligothiophenes

Quaterthiophenes containing a median 3,3′-dimethoxybithiophene (4MTZ) or bis(3,4-ethylenedioxythiophene) (4ETZ) block and an azobenzene group attached at two internal β-positions of the end thiophene rings have been synthesized. The analysis of the crystal structure of the two compounds by X-ray diffraction shows that, for 4MTZ, the quaterthiophene chain adopts a syn - anti - syn conformation similar to the parent system based on unsubstituted quaterthiophene. In contrast, 4ETZ presents an all-anti conformation stabilized by noncovalent intramolecular interactions between oxygen atoms and thiophenic sulfur atoms. The effect of the photoisomerization of the azobenzene group on the electronic properties of the attached π-conjugated quaterthiophene chain has been analyzed by UV-vis spectroscopy and cyclic voltammetry. The results obtained for 4MTZ suggest very limited geometrical changes due to the restricted rotation around the central interannular single bond caused by steric interactions between the methoxy groups. In contrast, upon trans to cis photoisomerization of the attached azobenzene group of 4ETZ, the quaterthiophene chain undergoes a reversible conformational switch to a final state with a lower HOMO level and a larger HOMO-LUMO gap than the initial state.
