AbstractPhotostability measurements have been made on thin films containing amorphous polycarbonate and an organic chromophore, 2-{3-Cyano-4-[3-(l-decyl-1H- pyridn-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. © 2009 American Institute of Physics.
