Abstract
Sterically stabilized second-order nonlinear optical chromophores and devices incorporating the same are embodied in a variety of chromophore materials. An exemplary preferred chromophore includes an electron donor group, an electron acceptor group and a ring-locked bridge structure therebetween, with the bridge structure being directly connected to the electron donor via a single bond. Another exemplary preferred chromophore includes an electron donor group, an electron acceptor group and a ring-locked bridge structure between the electron donor group and the electron acceptor group, with two free double bonds, one located between the donor and the bridge and the other located between the (fused) ring bridge and the acceptor. Another exemplary preferred chromophore includes an electron donor group, an electron acceptor group, and a bridge structure therebetween, with the chromophores having no carbon-carbon double bond between the donor and the (fused) ring bridge. In this class, there is only one unlocked carbon-carbon double bond between the (fused) ring bridge and the acceptor. Another exemplary preferred chromophore includes an electron donor group, an electron acceptor group, and a ring-locked bridge structure therebetween, with a built-in electron-withdrawing cyano group on the last ring of the (fused) bridge. Another exemplary preferred chromophore includes any electron donor group, an electron acceptor group including a linear conjugated triene bearing four cyano groups, and any bridge structure therebetween.
