采用固定光谱（紫外-可见吸收、共振拉曼光谱）和超快时间分辨光谱（可见、红外吸收）研究了fac-[Re(Cl)(CO)(3)(papy)(2)]和fac-[Re(papy)-(CO)(3)(bpy)](+) （papy =反式-4-苯并吡啶）配合物fac-[Re(Cl)(CO)(2)]的低空电子激发态特征和动力学。[Re(Cl)(CO)(3)(papy)(2)]在400 nm处的激发指向(1)pi pi*(papy)和Re -> papy (MLCT)- m -1激发态。超快(
The character and dynamics of low-lying electronic excited states of the complexes fac-[Re(Cl)(CO)(3)(papy)(2)] and fac-[Re(papy)-(CO)(3)(bpy)](+) (papy = trans-4-phenylazopyridine) were investigated using stationary (UV-Vis absorption, resonance Raman) and ultrafast time-resolved (visible, IR absorption) spectroscopic methods. Excitation of [Re(Cl)(CO)(3)(papy)(2)] at 400 nm is directed to (1)pi pi*(papy) and Re -> papy (MLCT)-M-1 excited states. Ultrafast (
