一系列供体-受体分子的光诱导电子转移速率（4，4 '-R 2-2，2'-联吡啶）2 Ru（1-（4-CH 3-2，2'-bipyridine-4'-yl-（CH 2）n）-4，4'-bipyridinediium-1'-R'）4+（R=H，CH 3 ; R '= CH 3，CH 2CN; n=1，2）的光化学性质进行了研究。在乙腈中，分子内正向ET（MLCT猝灭）的速率随-Δ Go的变化符合经典的Marcus理论（n=2），但不符合经典的Marcus理论（n=1）
The rates of photoinduced electron transfer (ET) in a series of donor-acceptor molecules (4,4'-R 2 -2,2'-bipyridine) 2 Ru(1-(4-CH 3 -2,2'-bipyridine-4'-yl-(CH 2 ) n )-4,4'-bipyridinediium-1'-R') 4+ (R=H, CH 3 ; R'=CH 3 , CH 2 CN; n=1, 2) were studied by picosecond flash photolysis/transient absorbance techniques. The rate of intramolecular forward ET (MLCT quenching) in acetonitrile varied with -ΔG o according to classical Marcus theory for n=2, but not for n=1
