Abstract
The microwave-enhanced synthesis, comparative singlet oxygen sensitization efficiency, and nonlinear optical characterization of a new β- functionalized porphyrin and its copper complex are described. We show that the introduction of a donor-acceptor push-pull conjugated fragment in the âposition strongly perturbs the porphyrin electronic structure leading to a remarkable one- and two-photon NIR absorption enhancement. © 2006 American Chemical Society.
