Synthesis and photochromic properties of substituted 3H-naphtho [2,1-b] pyrans
Synthesis and photochromic properties of substituted 3H-naphtho [2,1-b] pyrans
The synthesis and spectroscopic properties of novel 3H-naphtho[2, 1-b]pyrans are described. Subtle variation of the colour of the photo-generated merocyanine dyes derived from these naphthopyrans can be accomplished by controlling the steric interactions between a terminal pyrrolidine donor group and a proximal substituent.

Abstract
The synthesis and spectroscopic properties of novel 3H-naphtho[2, 1-b]pyrans are described. Subtle variation of the colour of the photo-generated merocyanine dyes derived from these naphthopyrans can be accomplished by controlling the steric interactions between a terminal pyrrolidine donor group and a proximal substituent.
