新的配合物[Ru（tpy）（Me（2）dppn）（py）]（2+）在甲基取代基的空间位阻诱导下，能在CH_3CN中有效地光解py（Phi（500）= 0.053（1）），并从其长寿命的（3）π π（*）激发态生成O-1（2）（Phi（Delta）= 0.69（9））.利用超快瞬态吸收光谱研究了导致双反应性的独特激发态过程。
The new complex [Ru(tpy)(Me(2)dppn)(py)](2+) efficiently photodissociates py in CH3CN with Phi(500) = 0.053(1) induced by steric bulk from methyl substituents and produces O-1(2) with Phi(Delta) = 0.69(9) from its long-lived (3)pi pi(*) excited state. The unique excited state processes that result in dual reactivity were investigated using ultrafast transient absorption spectroscopy.
