  摘要：

  在波长为 337 和 430 或 470 纳米的光下光解 1,3-二氢-5-(2-羟基-1-萘亚甲基亚氨基)-1,3,3-三甲基螺[2H-吲哚-2,3-[3H]-萘并[2,1-b]吡喃]光功能化合物 (PBC)所产生的中间产物的光谱动力学特性、1,3-二氢-5-(2-羟基-1-萘亚甲基亚氨基)-1,3,3-三甲基螺[2H-吲哚-2,3-[3H]-萘并[2,1-b]吡喃]，其分子结合了螺萘并吡喃和羟基氮甲基片段。,在甲醇和甲苯中研究了萘亚甲基亚胺和螺萘并吡喃的参数。相对于模型化合物，测量了形成 PBC 不同中间体的相对量子产率，即偶氮亚甲基片段中顺反异构和原向平衡形成的反式酮异构体，以及螺键打开产生的美蓝形式。研究发现，波长为 λ = 430 或 470 纳米的光对 PBC 进行光解时，几乎不产生美花氨酸形式，而反式酮同系物的相对产率为 0.6。在 λ = 337 纳米波长下进行 PBC 光解时，美拉德菁形式的产率为∼0.2，反式酮异构体的产率大幅下降（≤0.2）。溶剂性质会影响体系的动力学行为。讨论了异构化和质子转移过程的一致性。

  Intramolecular processes occurring in a photobifunctional compound (PBC) comprising the spironaphthopyran and hydroxyazomethine moieties have been studied in methanol solutions by femtosecond laser photolysis using light with wavelengths of 340 and 490 nm. At the excitation wavelength of 490 nm, the cis-trans photoisomerization in the azomethine moiety occurs in the S-1 state. In the case of PBC photolysis with 340-nm light, the opening of the spiro bond of the spiropyran moiety (formation of the X form) also takes place during relaxation of the S-n state to the S-1 state followed by isomerization to the merocyanine form. The spectral and kinetic characteristics of different electronically excited have been were determined. The data have been compared with those of nanosecond laser photolysis.
