Heron, B. Mark, Gabbutt, Christopher D., Hepworth, John D., Thomas, David A., Kilner, Colin and Partington, Steven M. (2004) Synthesis and Photochromic Properties of Methoxy Substituted 2,2-Diaryl-2H-naphtho[1,2-b]pyrans. Heterocycles, 63 (3). pp. 567-582. ISSN 0385-5414
Abstract

A series of methoxy-substituted 2,2-di(4-methoxyphenyl)-2H-naphtho[1,2-b]pyrans has been synthesised from 3-alkoxycarbonyl-1-naphthols and 1,1-di(4-methoxyphenyl)prop-2-yn-1-ol. The influence of the methoxy group on the wavelength of maximum absorption and the stability of the ring-opened naphthopyrans is discussed.
