摘要：
In this paper, we have reported the behavior of intramolecular charge transfer (ICT) state of p-N,N-dimethylaminobenzoic acid (DMABA) and p-N,N-dimethylaminobenzonitrile (DMABN) in n-heptane/AOT/water, n-heptane/AOT/methanol and n-heptane/AOT/acetonitrile reverse micelles. The different features of ICT emission of both the probes in water, methanol and acetonitrile reverse micelles are explained by the presence and absence of hydrogen bonded ICT state in the above-mentioned reverse micelles. Moreover, we have reported the decay characteristics of both the probes in locally excited (LE) and ICT state in these three reverse micelles. (C) 2004 Elsevier B.V. All rights reserved.
