Novel aggregation induced emission based 7-(diethylamino)-3-(4-nitrophenyl)-2H-chromen-2-one for forensic and OLEDs applications
Applied Surface Science Advances
In this report, a novel solvatochromism, aggregation induced emission (AIE) based 7-(diethylamino)-3-(4-nitrophenyl)-2H-chromen-2-one fluorescent probe (CFP) was synthesizes via one-pot multi-component reaction system under ultrasonication method. The synthesized CFP was characterized using different instrumental techniques namely, Fourier transform infrared spectroscopy (FTIR), Proton nuclear magnetic resonance spectroscopy (1H NMR), Mass spectrometer, Scanning electron microscope (SEM),
... oscope (SEM), Energy dispersive X-ray analysis (EDAX), Thermal gravimetric analysis (TGA), Transmission electron microscopy (TEM), UV−Vis spectrometry and Fluorescence spectrophotometer. The synthesized CFP produces red emission in solid as well as in liquid state. The synthesized CFP was investigated as a new labeling mediator for the visualization of latent fingerprints (LFPs) on the different non-porous materials surface. The obtained CIE result proves that the organic moiety was extremely helpful for the fabrication of red-light emitting diodes in the display device. The synthesized CFP will play a crucial role in visualizing the LFPs on various materials surface, organic light emitting diodes (OLEDs) and anti-counterfeiting applications.
