Kinetics of photochromic reactions of substituted azobenzenes in solutions, and in liquid crystalline and polymer matrices
PublicationBadano kinetykę fotochromowych reakcji pochodnych azobenzenu: eterów koronowych z resztą benzenu i 4-metoksy-4´-halogenoazobenzenów zdolnych do tworzenia fazy ciekłokrystalicznej. Fotoaktywne związki rozpuszczano w alkanach, polimerach i w ciekłokrystalicznej matrycy. Izomeryzacja odpowiada kinetyce pierwszego rzędu w niektórych polimerach, jednakże stwierdzono zróżnicowanie stałych szybkości reakcji. Termiczna izomeryzacja cis-trans...
