Abstract: Study of colorful compounds using Raman spectrometry can reveal crucial issues especially if fluorescent background is present. Fluorescence effect in flavonoids is shifted to higher wavelengths by the excited state intramolecular proton transfer. Therefore, new… read more here.

Abstract: Propanedioyl dihydrazide (PDH), traditionally believed to be non-fluorescent, was first discovered to emit substantial fluorescence in both the solid state and solvents. Then, significantly, a novel strategy is provided: fluorescent non-aromatic small molecules with rigid… read more here.
