The object of the present invention is to provide a photobase generator capable of efficiently generating amines (tertiary amines and amidine) high in catalytic activity by sensing light with a wavelength of from 350 to 500 nm (especially, from 400 to 500 nm).
The present invention is a photobase generator characterized in being represented by general formula (1) or (2).
Y+ is a quaternary ammonio group of general formula (3) to (5), and X− is a counter anion selected from among a borate anion, a phenolate anion, and a carboxylate anion.

The photorearrangement of a few 9,10-disubstituted-naphthobarrelenes to the corresponding naphthosemibullvalenes has been examined. It was observed that the regioselectivity in these photoisomerizations depends on the relative stabilities of the diradical intermediates. AM1 semi-empirical calculations are in support of this view. Thermal transformation of the naphthosemibullvalenes gave the corresponding
