摘要：
Novel substituted - 6, 8-dinitro - 1', 3', 3' - trimethylspiro [2H - 1 - benzopyran - 2, 2' - indoline] derivatives have been synthesized in high yields, and their properties are investigated. The at,sorption max;ima of the ring-open forms and the negative photochromic properties of spirobenzopyrans significantly depend on the substituents in the indoline ring and on the nature of the solvent used.
