| Popis: | The photochemical and photophysical behavior of several ((N,N-dimethylamino)alkyl)styrenes in which the amino group is attached to the styrene α- or β-carbon by a methyl, ethyl, propyl, or butyl polymethylene chain has been investigated. Efficient intramolecular addition of an aminomethyl C-H to styrene is observed in nonpolar. solvents for the (aminoethyl)styrenes, and addition of an aminomethylene C-H is observed for the (aminobutyl)styrenes. However, the (aminomethyl)- and (aminopropyl)styrenes do not undergo intramolecular addition reactions. Both the reactive and unreactive (aminoalkyl)styrenes form fluorescent singlet exciplexes in nonpolar and polar solvents |
