Abstract
Photoisomerization was found to take place both in distyryl (1) and bis (p-dimethylaminostyryl) (2) substituted organoboron compounds. Photodecomposition simultaneously proceeded in 1. The compound 2 did not show noticeable photodecomposition in isopropyl alcohol (IPA) but was found to show rapid photodecomposition in halogenated solvents such as carbon tetrachloride. Benzoylperoxide was observed to facilitate photodecomposition of 2 even in IPA. Photolysis of 2 dispersed in polymer matrices was also examined. The photodecomposition rate was increased with dielectric constants of the polymers.
