Paper Abstract

Jet-cooled spectroscopy has been carried out on non-sulfonate containing derivatives of the fluorescence probe molecules 1,8 ANS and 2,6 TNS. The absence of the sulfonate groups makes for straightforward sample volatilization without decomposition, yet fundamental features in the excitation spectra should be largely unchanged in ANS/TNS. The analogs studied can be viewed as naphthalenes with significant perturbations due to group substituents, the most important element of which is the amino nitrogen. The ultimate interest of this work will be ANS/TNS solvent complexation experiments, where photophysical changes may be induced by specific solvent-solute interactions. An intermediate point in the project will be analogous complexation experiments with anilinonaphthalenes, where there are indications that the results might mirror the ones seen with ANS/TNS.
