Newly synthesized, differently substituted chalcones (1,3-diaryl-2-propen-1-ones) have been studied using steady-state and time-resolved techniques combined with quantum-chemical modelling. To explore spectroscopic structure - property relationships

In this article, we report the photophysical properties of six, newly synthesized donor-substituted 2-amino-1,3-dicyano-5,6,7,8-tetrahydronaphthalene fluorophores. The steady-state and time-resolved spectroscopic experiments have been used to investi

The effects of α- and β-cyclodextrins (CDs) on the both emission modes (LE – locally excited and TICT – twisted intramolecular charge transfer) of the fluorescence spectrum of methyl-p-dimethylaminobenzoate (I) and its o-methoxy (II) derivative
Publikováno v:
Journal of Molecular Liquids. 157:61-66
Steady-state spectroscopic studies of ortho (–OCH3 and –OH) derivatives of methyl p-dimethylaminobenzoate indicate that molecules under study are capable of simultaneously creating locally excited (LE) and intramolecular charge transfer (ICT) exc
