摘要：

New thermo- and photochromic dyes, viz. bis-indolinospirobenzopyrans (BSPs, 3a-c) have been synthesized by the reaction of bis-Fischer bases (BFBs, 2a-c) with 2-hydroxy-5-nitrobenzaldehyde. The BFBs were prepared from the reaction of 5-amino-Fischer base with the corresponding diacyl halides. The synthesized BSPs have been characterized by 1H-NMR, IR, UV-VIS, and mass spectroscopy.
