Abstract

Two novel amino-substituted spiroindolinonaphthopyrans have been synthesised. Whilst these compounds exhibit no observable photochromic properties at ambient temperature, protonation gives stable, intensely coloured dyes. 1H nmr spectroscopy has been used to establish the configuration of these dyes
