Bichromophores Increasing Excited-State Lifetimes

Hanan and coworkers have applied the bichromophoric approach with considerable success to the Ruterpy complexes.103160 Compound 12 shows excited state equilibrium between an anthracene 3LC state and a Ruterpy 3MLCT state leading to room temperature luminescent lifetime of 1052 ns which is compared to 250 ps for [Ru(terpy)2]2+.102
