概要 | Electron transfer processes were studied for novel mech. linked triad [2]rotaxanes, which contain a porphyrin (MP) unit as a pendant and [60]fullerene (C60) and triphenylamine (TPA) moieties as stopper groups at the axle ends (abbreviated as (MP;C60-TPA)rot+ with MP = H2P or ZnP). The charge sepn. took place mainly via (1MP*;C60-TPA)rot+ and (MP;1C60*-TPA)rot+ in polar solvents. Within the charge-sepd. states of the triad (MP;C60-TPA)rot+, hole-shift and/or back electron transfer took place competitively. The lifetime of the charge sepn. state of (ZnP;C60-TPA)rot+ was similar to that of dyad (C60-TPA)rot+ (140 ns in dimethylformamide), whereas that of (H2P;C60-TPA)rot+ was as long as 230 ns, suggesting two final charge sepn. states such as (MP;C60·--TPA·+)rot+ and (MP·+;C60·--TPA)rot+ depending on the kind of porphyrin. |
