The photophysical and photochemical behavior of a series of secondary and tertiary ω-(β-styryl) aminoalkanes with one to five methylenes separating the styryl and amino groups has been investigated and compared to the intermolecular reactions of 1-phenylpropene with secondary and tertiary amines. The effects of polymethylene chain length, solvent polarity, temperature, and the bulk of the N-alkyl group

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
