摘要：
Four novel fluorescence dyes of the pyrazoline were synthesized and fully characterized by means of H-1, C-13 NMR, and HRMS. The optical, electrochemical properties were also investigated. Solvent effect on the fluorescence characteristics of the four compounds indicates that the emission wavelength was red-shifted with the increase of solvent polarity. As we expected, the results indicated that these compounds exhibited high quantum yields. Quantum chemical calculations were used to obtain optimized ground-state geometry, spatial distributions of the HOMO, LUMO levels of the compounds. (C) 2012 Elsevier B.V. All rights reserved.
