Heterocyclic Quinol-Type Fluorophores: Synthesis, X-ray Crystal Structures, and Solid-State Photophysical Properties of Novel 5-Hydroxy-5-substituent-benzo[b]naphtho[1,2-d]furan-6-one and 3-Hydroxy-3-substituent-benzo[kl]xanthen-2-one Derivatives

properties have been investigated in solution and in the solid state. Considerable differences in the absorption and fluorescence spectra were observed between the two states. Quinols 4 a-c and 5 a-c exhibited almost the same absorption and fluorescence spectra in solution; however, their solid-state fluorescence excitation and emission spectra in the crystalline state were quite different. We performed
合成了新的杂环喹诺型荧光团(4 ac)和(5 ac),它们含有与发色团骨架非共轭键的取代基(R = Me,Bu,Ph),并已在溶液和固体中研究了它们的光物理性质状态。在两种状态之间观察到吸收光谱和荧光光谱有相当大的差异。喹诺酚4 ac和5 ac在溶液中表现出几乎相同的吸收光谱和荧光光谱。然而,它们在结晶态下的固态荧光激发和发射光谱是完全不同的。我们进行了X射线晶体学分析,以阐明非共轭键的取代基对固态荧光激发和发射光谱的显着影响。
