AbstractThe photostabilities of a series of nonlinear optical (NLO) polyimides containing two different chromophores were measured at 655 nm where the spectral response is dominated by separated chromophores rather than J-aggregation. We investigated the effect of ring-locking of the chromophore conjugated backbone, variations in the chromophore number density and the incorporation of an anti-oxidant. We found that none of these modifications altered the initial photodegradation at 655 nm.
