Spectrochim Acta A Mol Biomol Spectrosc. 2018 Jan 15;189:601-607. doi: 10.1016/j.saa.2017.08.070. Epub 2017 Sep 01.

We present the absorption and fluorescence spectra of (E)-N-(4-(dimethylamino)benzylidene)-2H-1,2,4-triazol-3-amine (DMABA-Amtr), an electron donor-π-acceptor system. The molecule shows a single fluorescence emission band in non-polar solvents while dual emissions were observed in polar aprotic solvents. Although several researchers over the...

Merocyanine 540 fluorescence can be enhanced by optically depopulating dark photoisomer states to regenerate the fluorescence-generating manifold of the all-trans isomer. Here, we utilize a competing modulation route, long-wavelength coexcitation of the trans triplet population to not only modulate...
