By using a merit of visuality and high sensitivity of fluorescence emission, the following novel multi-functional fluorescent dyes or molecular systems have been designed, synthesized, and their fluorescence response behaviors upon external or enviromental stimulations were investigated.1.Quinol-type fluorescent host : Novel quinol-type fluorescent hosts which can form clathrate crystals with various organic solvent molecules have been synthesized. Very interestingly, the fluorescence emission of host crystals were dramatically enhanced upon enclathration of the guest molecules.2.Fluorescent dichroic dye : Novel benzofuranoquinol-type fluorescent dyes with appropriate dichroic properties showed good fluorescent dichroic properties in an ordered nematic liquid crystal.3.Imidazoanthraquinone-Type dye : These dyes having quinoid structure were found to exhibit good reversible color-fluorescence switching behaviors upon voltage application.4.Luminescent chemosensor for metal ions : Novel ICT-type and PET-type fluorescent chemosensors based on imidazoanthraquinone chromophore have been synthesized and their sensing ability for metal ions was inverstigated. The PET sensor exhibited more sensitive fluorescence enhancement upon metal complexation than the ICT sensor.5.Luminescent metalloreceptor for phosphodiesters : Novel tris (2,2'-bipyridyl) ruthenium complexes prossessing acylamino-imizazoline or aminoimidazoline groups have been synthesized. The absorption and liminescence properties of the complexes were highly sensitive to discriminate between phosphodiesters and phosphodiester anions.

利用荧光发射的可视性和高灵敏度的优点，设计、合成了以下新型多功能荧光染料或分子体系，并研究了它们在外界或环境刺激下的荧光响应行为。喹啉型荧光宿主：合成了新型喹啉型荧光宿主，能与多种有机溶剂分子形成包合物晶体。非常有趣的是，在客体分子包合后，宿主晶体的荧光发射显著增强。荧光二向色染料：具有合适二向色性的新型苯并呋喃醌类荧光染料在有序向列液晶中表现出良好的荧光二向色性。咪唑蒽醌型染料：这些具有醌类结构的染料在电压作用下表现出良好的可逆颜色荧光切换行为。金属离子发光化学传感器：合成了基于咪唑蒽醌发色团的新型ict型和pet型荧光化学传感器，并研究了它们对金属离子的传感能力。在金属络合作用下，PET传感器比ICT传感器表现出更灵敏的荧光增强。磷酸二酯的发光金属受体：合成了新的三（2,2'-联吡啶）钌配合物，处理酰基咪唑啉或氨基咪唑啉基团。该配合物的吸收和发光特性对磷酸二酯和磷酸二酯阴离子具有高度敏感性。
