The charge transfer (CT) compexes formed between pyrene with some Dinitrobenzenes (DNB) and 1,3,5-Trinitrobenzene (TNB) acceptors are studied in solution and solid state using UV-visible, infrared and fluorescence spectroscopies.The equilibrium constants (Kc) for these complexes in solution have been calculated.The values of Kc follow the order o-DNB > m-DNB p-DNB TNB.This order is explained by considering the role that steric effects may play in the CT complex formation.In addition, the fluorescence quenching of pyrene with different acceptors is investigated.The effect of medium viscosity and temperature on the efficiency of quenching is also studied.Finally, the electrical properties for the solid CT complexes are measured. - Keywords: Pyrene CT complexes / Equilibrium constants / Fluorescence quenching / Electrical conductivity
