Abstract :
The steady state fluorescence of P-(N,N-diphenylamino)benzoic acid methyl ester (DPABME) in ethanol is broad and is composed mainly of the intramolecular charge transfer (ICT) band ~490 nm and a shoulder ~400 nm due to normal fluorescence of charge transfer character. In acetonitrile only the long fluorescence (ICT) band ~480 nm could be observed. In n-butylchloride, only the short fluorescence ~420 nm could be observed. The competition between the two fluorescence bands is discussed and confirmed by fluorescence decay, time resolved fluorescence (TRF) spectra and red edge effect (REE) results.
