摘要
以系列异戊氧基空心酞菁和金属酞菁为研究对象,采用纳秒激光闪光光解法对浓度为10-5mol.L-1的酞菁溶液进行了三线态激发态吸收性质研究,获得了三线态吸收曲线,并测定了酞菁配合物的三线态寿命。由于d电子和金属-配体之间电荷转移等因素的影响,ZnPc(OC5H11)4具有较强的三线态吸收和较长的三线态寿命。
A series of iso-pentyloxy substituted metal free phthalocyanines and metallophthalocyanines were studied. The nanosecond flash photolysis technique was employed to investigate the triplet absorption properties of phthalocy- anines in solutions at the concentration of 10-5 mol · L-1 , by which the triplet absorption curves were acquired and triplet lifetimes were determined. ZnPe ( 0C5 H,, )4 exhibits a strong triplet absorption and long triplet lifetime due to the factors of d-electron and charge transfer mechanism between metal and ligand.
