Observation and mechanism of photo-isomerisation induced rapid photo-degradation of optical nonlinearity in guest-host type poled polymer
- 1. Fudan University, Shanghai (China)
Description
Photo-degradation of electric field poled alpha'-cyano-4'-nitro-4-N,N-dimethylaminostilbene (CNDS) doped polymer was investigated by second-harmonic generation (SHG), UV-Vis absorption and FTIR. We found that the addition of a cyano group makes CNDS much more easily photoisomerized, and thus destroys the molecular ordering in poled chromophore doped polymers. A comparison experiment revealed that the photo-isomerization of CNDS is even easier than that of a modal system of azobenzene, which shows that CNDS has potential applications, such as in optical switches.
