photochemical properties of 4-hydroxybenzylidene imidazolinone (HBI), a GFP-related chromophore, imidazolidinone and imidazothiazolone analogues have been studied as fluorescent probes. Their photoisomerization and their thermal reversion were studied under 365-nm-irradiation, resulting in observation of an enthalpy–entropy compensation effect. Theoretical studies were carried out to shed light on the
由于密闭环境对 4-羟基苯亚甲基咪唑啉酮 (HBI)(一种 GFP 相关发色团)的光化学性质有显着影响,咪唑啉酮和咪唑并噻唑酮类似物已被研究作为荧光探针。在 365 nm 照射下研究了它们的光致异构化和热回复,从而观察到了熵补偿效应。进行了理论研究以阐明热回复机制。此外,在 dsDNA 存在下,亚苄基咪唑噻唑酮的光物理研究揭示了荧光增强。所制备的化合物可被视为详细研究物理化学、生物化学或生物系统的有价值的工具。
