具有分子内电子转移特征的氨基蒽醌类有机化合物的合成 及光物理性质研究

合成了一系列1,5-二烷基氨基蒽醌类和含有可光致聚合CH2＝CHCO2基团且具有分子内电子转移特征的烷基氨基蒽醌类有机光功能化合物. 通过1H NMR, IR和MS对合成的化合物进行了结构鉴定. 通过光引发测试等实验证明, 含有可光致聚合CH2＝CHCO2的基团、具有分子内电子转移特征的烷基氨基蒽醌/邻氯六芳基双咪唑(HABI)体系, 在500 nm左右的可见光照射下, 且具有较快的光漂白速度和较高的光引发效率, 可以与Ar＋激光器匹配作为高效可见光敏聚合的光引发-吸收剂使用.

Synthesis and Study on Photophysical Properties of 1,5-Di-(N, N'-dialkylamino)-anthraquinone Derivatives with Intramolecular Electron Transfer Character

Some l,5-di-(N,N'-dialkylamino)-anthraquinones and their derivatives containing functional acryloyl groups were synthesized and characterized by 1H NMR,IR and MS. The photo-initiating systems composed of 1,5-di-N,N'-dialkylamino-anthraquinone derivatives or 1,5-di-(N,N'-dialkylamino)-anthraquinone containing acryloyl groups with HABI exhibited faster photobeaching rate and higher initiating efficiency under 500 nm visible light,thus can be used as photo-absorbing and photoinitiating materials which are suitable for Ar .
