Abstract :
Non-coherent photon upconversion by rapid intramolecular triplet–triplet annihilation has been observed following nanosecond laser excitation of Ru(dmb)3 and sequential two-fold triplet energy sensitization of a polymer containing 30 pendant diphenylanthracene groups. A global kinetic analysis of the system has been performed; the intramolecular annihilation step occurs on a sub-nanosecond time scale.
