Abstract

Propeller-shaped molecules based on a triphenylbenzene crux bearing three oligomeric phenylenevinylene branches have been designed; very large first-order hyperpolarisabilities (up to∥ β∥= 800 10− 30 esu) were obtained while maintaining wide transparency in the visible region by taking advantage and boosting of intramolecular charge transfer between the centre and the periphery.
