Abstract
Derivatives of DMABN are described, where the cyano group is replaced by an amide function with different acceptor strengths. This leads to a consistent variation of the dual fluorescence observed, describable within the established TICT model. Time resolved experiments give evid ence of an additional complication with respect to DMABN due to the lo w-lying n pi state of the amides which induces a fluorescence quenchi ng channel. The presence of various conformers leads to the observed n onexponential fluorescence decay traces.
