Dual nature of exciplexes: exciplex-forming properties of carbazole and fluorene hybrid trimers

Two exciplexes were detected for the first time for the known exciplex-forming system consisting of electron donating 1,3-bis(N-carbazolyl)benzene and electron accepting 2,4,6-tris[3-(diphenylphosphinyl)phenyl]-1,3,5-triazine.
