Abstract

Two-photon absorption (TPA) is a nonlinear optical process that is gaining increasing attention since it can be exploited in a number of optical applications. Here, on the basis of correlated quantum-chemical calculations, we investigate the structure-TPA property relationships for donor-acceptor π-conjugated compounds. These relationships provide strategies to design dyes with large TPA cross-sections for fundamental photon wavelengths in the desired 0.6-1.0 μm range of wavelengths.
