Various amino benzothiadiazoles (Am-BTDs) are synthesized and their photophysical properties in different states (solution, film, crystal, and powder) are investigated. Unusual anti-Kasha's emission is observed for those compounds with a strong electronic coupling effect between the donor and the acceptor which directly results in the white emission of those compounds in dilute solutions. Among these Am-BTDs, some of them can be utilized as fluorescent chemosensors in sensing gaseous ammonia, and some of them can be developed for detecting fluoride anions with high selectivity and high sensitivity. Moreover, aggregation caused quenching is not observed for these compounds in the solid state. They are emissive in films, crystals and powders with high color purity and moderate efficiencies. The emission color could be tuned from yellow to red according to the varying amino groups. Furthermore, they can be used as an emissive layer in organic light emitting diodes.

氨基苯并噻二唑产生的反卡沙辐射的表达及其在荧光化学传感器和有机发光材料中的应用

合成了各种氨基苯并噻二唑(Am-BTDs),并研究了它们在不同状态(溶液,薄膜,晶体和粉末)的光物理性质。在供体和受体之间具有很强的电子耦合作用的那些化合物中观察到了不寻常的抗-Kasha发射,这直接导致了这些化合物在稀溶液中的白色发射。在这些Am-BTD中,其中一些可以用作荧光化学传感器来检测气态氨,并且可以开发其中的一些以高选择性和高灵敏度检测氟化物阴离子。此外,对于固态的这些化合物未观察到聚集引起的猝灭。它们可在具有高色纯度和中等效率的薄膜,晶体和粉末中发光。发光颜色可以根据氨基的变化从黄色变为红色。此外,它们可以用作有机发光二极管中的发射层。
