Synthesis and photophysical properties of charge transfer cocrystals based on TCNB and fluorene and its derivatives

A series of charge transfer cocrystals with fluorescent properties involving 1,2,4,5-tetracyanobenzene (TCNB, C10H2N4) as the acceptor, fluorene (FR, C13H10) and its bromide 2-bromofluorene (2-BrFR, C13H9Br), carbazole (CZ, C12H9N) and its...
