| Research Abstract |
Poly(amide acid) gels containing photosensitive azobenzene groups in the main chain have been synthesized. It was found that 405 nm light induced a decrease of local volume due to trans-cis isomerization and 532 nm light irradiation increases a volume of gel.
The gel works as a photosensitive pump that discharge solvent by blue laser irradiation and aspirate solvent under visible light irradiation. The discharge amount of solvent under one pulsating is estimated to be 1×10^<-10> m^3. The discharge amount of solvent from polymer gels synthesized with tetrafunctional crosslinker is 20% larger than that of polymer gels synthesized by use of trifunctional crosslinker.
