Popis:	A series of 3,3-diphenyl-3H-naphtho[2,1-b]pyrans substituted on 5-position by various nitrogenated functional groups has been synthesized. The photochromic reaction between the pyranic closed form and their open forms has been studied using NMR and UV–Vis spectroscopies. The ability of the photoinduced carbonyl group to promote the formation of hydrogen-bonded complexes has been compared within the series. Copyright © 2007 John Wiley & Sons, Ltd.
