Photostability Studies on Zwitterionic Chromophores for Nonlinear Optics
Abstract
Photostability measurements have been made on thin films containing amorphous polycarbonate and an organic chromophore, 2-{3-Cyano-4-[3-(1-decyl-1H-pyridin-4-ylidene)-propenyl]-5, 5-dimethyl-5H-furan-2-ylidene}-malononitrile. We find that the photodegradation quantum efficiencies for films containing 15% chromophore loading by weight are similar to those with lower chromophore loadings. The photodegradation quantum efficiency dramatically decreases by more than 3 orders of magnitude when the films are encapsulated to minimise exposure to oxygen.
