Notizen:
Photochromism of the o-Nitrobenzylpyridines in Supercooled Melts2-(2′, 4′-dinitrobenzyl)-pyridines 1 a-g and 4-(2′,4′-dinitrobenzyl)-pyridine 2 form supercooled melts which are photochromic on u.v.-irradiation. The photochromism and the kinetic stability of the coloured form in supercooled melts are quite different from the behaviour in ethanolic solution. The differences are explained on the basis of a polymethin constitution of the coloured form.
