The complexes Ir(III)(nbd(2)(2-))(L-L)(acetylacetonate) with nbd(2)(2-) = bis-norbornadienyl dianion and L-L = norbornadiene and 2,2'-bipyridyl and Pd(II)[C-4(COOMe)(4)](2,2'-bipyridyl) contain metallacycles and a diolefin or bipyridyl as additional ligand. These complexes are characterized by low-energy LLCT excited states. The CT donor site is associated with the metallacycle while the CT ...

The complexes Ir(III)(nbd(2)(2-))(L-L)(acetylacetonate) with nbd(2)(2-) = bis-norbornadienyl dianion and L-L = norbornadiene and 2,2'-bipyridyl and Pd(II)[C-4(COOMe)(4)](2,2'-bipyridyl) contain metallacycles and a diolefin or bipyridyl as additional ligand. These complexes are characterized by low-energy LLCT excited states. The CT donor site is associated with the metallacycle while the CT acceptor function is provided by a diolefin or bipy. The LLCT triplets are emissive in solution under ambient conditions. (C) 2015 Elsevier B.V. All rights reserved.
