Rd. Miller et al., DONOR-EMBEDDED NONLINEAR-OPTICAL SIDE-CHAIN POLYIMIDES CONTAINING NO FLEXIBLE TETHER - MATERIALS OF EXCEPTIONAL THERMAL-STABILITY FOR ELECTROOPTIC APPLICATIONS, Macromolecules, 28(14), 1995, pp. 4970-4974
We describe here the preparation and characterization of the first pro
cessible nonlinear optical (NLO) polyimide where the chromophore is no
t incorporated using a flexible tether functionality. The polymer has
a very high glass temperature and shows exceptional thermal and chemic
al stability. Poled samples also show outstanding orientational stabil
ity, consistent in part with the high glass transition temperature.
