Novel pyrazoline optical materials were synthesized and characterized using H-1, C-13 NMR and HRMS: the thermal, optical and electrochemical properties of the compounds were also investigated. Solvent effects on the fluorescence of the six compounds indicated that the emission wavelength was red-shifted with increase in solvent polarity. Quantum chemical calculations were used to obtain optimized ground-state geometry as well as spatial distributions of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) levels of the compounds.
