benzyl ether dendrimer silicon(IV) phthalocyanines with nitro/cyano/ether terminal functional groups were synthesized. The structures of these compounds were characterized by elemental analysis, IR, 1H NMR, thermogravimetric analysis and MALDI-TOF mass spectroscopic data. Photophysical properties, photoinduced intermolecular electron transfer constants, and photoinduced intramolecular energy transfer efficacies
合成了三种具有硝基/氰基/醚末端官能团的新型芳基苄基醚树枝状硅(IV)酞菁。这些化合物的结构通过元素分析IR 1表征1 H NMR,热重分析和MALDI-TOF质谱数据。通过紫外/可见和荧光光谱法比较了三种树枝状大分子酞菁硅(IV)酞菁的光物理性质,光诱导的分子间电子转移常数和光诱导的分子内能量转移效率。通过循环伏安法(CV)和方波伏安法(SWV)测量研究了这些树枝状硅(IV)酞菁的电化学行为。具有硝基基团的树状大分子硅(IV)酞菁具有最高的光收集能力,荧光量子产率和光诱导的分子内能量转移功效。我们的研究表明,这种新型的树枝状大分子酞菁硅是一种有效的能量传递复合物,具有很高的效率,
