摘要：

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. H-1 nmr spectroscopy has been used to establish the configuration of these dyes. (C) 1999 Elsevier Science Ltd. All rights reserved.
