摘要：

选用柠檬酸和三乙烯四胺作为原料,在相对低温下(80 ℃),制备量子产率高达78%的荧光材料。通过紫外吸收、荧光、傅里叶变换红外光谱仪(FTIR)、核磁共振波谱仪(NMR)等技术手段对该体系进行表征。结果表明,该荧光材料属于非典型性荧光材料,其强荧光性可能源于体系中大量羰基的聚集。这种高量子产率材料满足制备隐形墨水的要求,在图案化、防伪和光电子设备等领域具有潜在的应用前景。

Abstract:

A fluorescent material with high quantum yield(78%) was prepared using citric acid and triethylenetetramine as initial reagents in a facile way. The as-prepared system was characterized by ultraviolet(UV) absorption, fluorescence, Fourier transform infrared spectrometer(FTIR), nuclear magnetic resonance spectroscopy(NMR). The results show that the product belongs to a typical fluorescent material and the aggregation of a large number of carbonyl groups in the system may cause its intense fluorescence. It is confirmed that the material with high quantum yield can be an excellent fluorescent ink. This material has wide potential applications in the fields of patterning, anti-counterfeiting and optoelectronic devices.

Key words: citric acid, triethylene tetramine, high quantum yield, fluorescent ink
