Research Abstract

We report a efficient charge separation triad systems where triphenylamine (D) and naphthalenediimide (A) are linked to the platinum complex moiety (Pt) through highly twisted phenylene ethynylene linkages. The quantum yields for the formation of the charge-separated states were determined to be nearly unity. The lifetimes of the full charge separated state (D^+-Pt-A^-) were approximately 1μs at room temperature and much longer at low temperature. The spin-correlated radical ion pair was directly observed by means of time-resolved EPR spectroscopy.
