Molecular Design, Synthesis and γray Detection of Novel Color Formers Having

Novel color formers 2 containing phenazine moiety for γray detection were designed based on the shades of chromophore 1. Color formers 2a-2c were synthesized from aromatic amines 4, 5 and 6 or dye 9·Cl- or 10·Cl- as starting materials. Acetonitrile solution of 2a, 2b or 2c was changed into correspon...

Summary:Novel color formers 2 containing phenazine moiety for γray detection were designed based on the shades of chromophore 1. Color formers 2a-2c were synthesized from aromatic amines 4, 5 and 6 or dye 9·Cl- or 10·Cl- as starting materials. Acetonitrile solution of 2a, 2b or 2c was changed into corresponding colored form 1a-1c by γirradiation. Identification of the structures of 1 was carried out with electronic absorption and mass spectrometry. 1a, 1b or 1c showed magenta, red or yellow shade respectively. Substituent R1-R4 introduced into 1 affected a remarkable shift of absorption maximum within visible range.
