Simple Spacer-Free Dye-Polyelectrolyte Ionic Complex: Side-Chain Liquid Crystal Order with High and Stable Photoinduced Birefringence
Source abstract
Abstract
A simple ionic azo-dye polyelectrolyte complex, free of flexible spacer and tail, was prepared from two readily available components. It possesses smectic A order from subambient to degradation (above 230 °C) and provides exceptional photoinduced birefringence (PIB) properties, competitive with if not superior to those of previously reported all-covalent azo polymers.

50. The PIB depends on the exposure dose (power of writing laser multiplied by writing time) and the intrinsic response of the chromophore at the writing wavelength used (photoisomerization quantum yield, cis−trans isomerization rate, etc.). Thus, comparisons possible depend on the information available and, in some cases, are extrapolated. A high exposure dose may also cause irreversible changes in the exposed region that affect potential relaxation processes.

53. Polyelectrolyte layer-by-layer assemblies involving covalently or noncovalently bound dyes can also show interesting photoinduced alignment (see, for example, ref1e); however, to the best of our knowledge, there are no reports of high PIB, only high dichroic ratios, which are not directly comparable.
