摘要:
以对吡啶甲醛和2-萘乙酮为原料,设计合成了一个简单的吡啶嗡盐,并研究其固态荧光及机械发光性质。通过对红外光谱、紫外可见吸收光谱、X射线粉末衍射以及荧光光谱的研究表明,该材料呈现高达41%的量子产率,而且,呈现可逆的机械变色发光特性。研磨前后的X射线粉末衍射研究表明,该材料的机械发光与其结晶形态有关。鉴于该有机发光材料合成简单且产率高,以及具有高荧光量子产率和可逆的机械变色发光特性,将可能应用于机械压力传感。
Abstract:
A simple pyridinium salt was synthesized from 4-Pyridinecarboxaldehyde and 2-acetonaphthone, and its solid state fluorescence and mechanical luminescence properties were studied. Based on Infrared spectra, UV-visible absorption spectra, X-ray powder diffraction and fluorescence spectra, it was found that this material exhibits high quantum yield with 41% and reversible mechanochromic luminescence. Based on powder diffraction before and after grinding, the mechanical luminescence of the pyridinium salt is related to its crystal morphology. In view of the fact that the organic luminescent material with high yield is easy to synthesize and exhibits high fluorescence quantum yield and reversible mechanochromic luminescence, it may be applied to mechanical pressure sensing.
