moment on excitation which results in the fluorescence quantum yield dramatically falling as the solvent polarity increases. A typical compound 4-(1-piperidyl)-N-(2-pyrimidinyl)-1,8-naphthalimide was chosen to determine the water content in six common solvents (p-dioxane, tetrahydrofuran, acetone, dimethylformamide, acetonitrile and methanol). Fluorescence intensity changes as a function of water content
A bisnaphthalimide-based fluorescent probe (BNAP) was synthesized for rapid detection of viscosity and viscosity-related temperature variations.

discovery of dual fluorescence. Because of their unique photophysicalproperties, these dual fluorescent systems represent an exception to the widely studied TICT (Twisted InternalChargeTransfer) fluorescent dyes or tautomeric benzofluorescein class of two-color dyes. The matrix library was designed to investigate the effects of heterocycles, particularly π-excessive and π-deficient systems. Of the
