Unique ultrafast energy transfer in a series of phenylene-bridged subporphyrin–porphyrin hybrids†
Abstract
A series of phenylene-bridged subporphyrin–Zn(II) porphyrin (SubP–ZnP) hybrid systems undergo extraordinarily fast excitation energy transfer (EET) processes from the SubP to the ZnP, aided by conjugative electronic elongation of the SubP to the phenylene-bridge.
