Abstract

Recent study of photoinduced processes in spiropyran systems of monomers and polymers with units such as I-A and II-A, leading to aggregation and quasi-crystal formation, has led to several publications.1-4 To determine whether there is a relationship between photoinduced conformational changes in polymers containing spiropyran units and photoinduced processes leading to spontaneous aggregation in I-A and II-A1 we have conducted a time-resolved study of homopolymer and copolymer solutions.5
