Abstract: | Imine- and hydrazone-based metal chelates containing a spiropyran fragment derived from 3-methyl-4-oxo[2H]-1,3-benzoxazinone were prepared. Attempts are made to monitor the photochromic activity of spiropyran using nontraditional -acceptor substituents (products of condensation of the formyl group in 6"-dimethyl-8"-formylspiro-(4-oxo-3,4-dihydro-2H-1,3-benzoxazine-2,2"-[2H]chromene) with o- aminophenol and aromatic acid hydrazides) and using transition metal ions. |
