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
