Abstract

Investigations of the non-linear optical properties of a novel series of A–π–A quadrupoles, based on dimesitylboron end-groups, reveal the promising potential of elongated vinylboranes derivatives for combined enhanced two-photon absorption cross-section and improved transparency in the visible region. In addition, the excited state lifetime can be significantly enhanced in A–π–A′–π–A derivatives. This opens a new route towards optimized molecules for optical power limiting.
