羟基取代对称恶碳菁染料的合成

Syntheses of Hydroxyl-Substituted Benzoxazole sym-Carboeyanine dyes

菁染料作为在近紫外至近红外区域内的光谱增感剂,其主敏化区受到分子结构中的次乙基链长度和不同杂环结构的影响。

A new series of benzoxazole carbocyanine dye may be a potencial photosensitizer in green region.The key intermediates of the synthetic sequence,hydroxyl-substituted benzoxazole,were synthesized from poly-hydroxy acetophenone oxime via Beckmann rearrangement conveniently.Four symmetrical carbocyanine dyes,and five intermediates of hydroxyl-subs-tituted benzoxazoles were synthesized.
