The photophysical properties of 4-cyano-4′-butyloxybiphenyl (4COB) in diluted solytion at room temperature are reported. From this study it is clear that 4COB forms an I(ntramolecular) C(harge) T(ransfer) state. Furthermore, the influence of the temperature on the formation of the ICT state of 4COB in 1-butanol and diethylether is investigated to study the role of the solvent dynamics on the stabilization of the ICT state. Finally the importance of hydrogen bonded clusters in the stabilizaiton of the ICT state of 4COB has been examined in 1-butanol/butronitrile mixtures.
