在薄玻璃波导上制备了四叔丁基锌酞菁 (Pc)、二柠檬酸二过氧钛酸酯络合物 (TAS) 和双十四烷基紫精 (V) 三元组的 Langmuir-Blodgett (LB) 薄膜作为级联电子转移模型。 LB工艺成功控制了Pc-TAS-V层的排列。由于空气-水界面处的多重静电相互作用，Pc 或 V 的单层与 TAS 层一起稳定。使用波导光谱法直接测量 Pc-TAS-V 三元组系统中通过 TAS 层从 Pc 到 V 的光致电子转移。相反分层顺序 V-TAS-Pc 中的电子转移可以忽略不计。根据这些结果，可以通过使用混合 LB 程序控制分层顺序来控制三元组中的电子转移方向。
Langmuir-Blodgett (LB) film of tetra-t-butyl-Zn-phthalocyanine (Pc), dicitratodiperoxotitanate complex (TAS) and ditetradecylviologen (V) triad was fabricated on thin glass waveguide as a cascade electron transfer model. The arrangement of the layer as Pc-TAS-V was successfully controlled by LB process. Monolayer of Pc or V was stabilized with TAS layer due to a multiple electrostatic interaction at air-water interface. Photoinduced electron transfer from the Pc to V through the TAS layer in Pc-TAS-V triad system was measured directly using waveguide spectroscopy. Electron transfer in the opposite layering sequence, V-TAS-Pc, was negligible. According to these results, direction of the electron transfer can be controlled in the triad by controlling the layering sequence using the hybrid LB procedure.
