Abstract

A molecular engineering strategy, based on the role of the charge transfer conjugated system, and of donor substituents on theoretical linear and two-photon absorption (TPA), is developed. The best trade-off TPA-linear absorption is fulfilled by two tetraphenyl-diamine derivatives (biphenyl and fluorene), which could allow, if mixed, to cover efficiently the visible range. Furthermore, the theoretical study of two-photon absorption (TPA) properties of polyphenyls (with the number of benzene monomer units n=1 to 6) is related to cooperative effects between monomers. These effects lead to an increase of the TPA cross-section with n without saturation according to a power law.
