“…The most investigated and commercially important groups are coumarins based dyes [1, 2, 3, 4]. Coumarin dyes exhibit intense fluorescence on substitution of various functional groups at different positions [5, 6, 7]. The fluorescence properties of coumarin derivatives can be altered by substituting different functional groups like amino, hydroxy and methoxy at the 7 th position.…”

A new series of solid state fluorescent disperse dyes based on hybrid structure of pyrrolinone ester (PES)/coumarin moiety was prepared and fully characterized using spectroscopic analysis such as 1 HNMR, MS and IR spectra. The coumarin derivative (7- amino-4- methyl coumarin) was initially prepared from amino phenol via multi steps condensation reactions and its diazonium salt coupled with the pyrrolinone ester to form the hydrazone dyes. 1 HNMR data of the prepared dyes exhibited a pure hydrazone form as a mixture of E , Z isomers. These dyes showing a significant emission in solid state as well as on the dyed fabric. The dyeing application on polyester fabrics was investigated which showing that these dyes show high affinity to polyester fabric, and minor change in the dye affinity by changing pH even under alkaline conditions was observed.

“…Notable photophysical properties of coumarins have turned them into extensive dyes for probing, brightening or labelling, as a function of substitution on the core structure and the interaction with the surrounding media [18][19][20][21][22][23][24]. Besides, coumarin compounds are widely used in the laser industry as laser dyes, as well as being reported as dopants in light-emitting diodes (LEDs and OLEDs) [25][26][27][28][29][30][31][32].…”

Polyurethanes are of undoubted interest for the scientific community and the industry. Their outstanding versatility from tailor-made structures turns them into major polymers for use in a wide range of different applications. As with other polymers, new, emerging molecules and monomers with specific attributes can provide new functions and capabilities to polyurethanes. Natural and synthetic coumarin and its derivatives are characterised by interesting biological, photophysical and photochemical properties. Then, the polyurethanes can exploit those features of many coumarins which are present in their composition to achieve new functions and performances. This article reviews the developments in the proper use of the special properties of coumarins in polyurethanes to produce functional and smart materials that can be suitable for new specific applications.

A coumarin-derived compound, 3-benzoyl-7-hydroxy coumarin (BHYC), is synthesized to determine its optoelectronic properties, including absorbance band edge, optical band gap, transmittance, refractive index, electrical susceptibility, volume-surface energy loss functions and optical/electrical conductance parameters. The absorbance spectra of BHYC in dimethylformamide (DMF) and dimethylsulfoxide (DMSO) solvents exhibit maximum peaks at 350 and 353 nm, respectively, in the near-ultraviolet region. The absorbance band edge values of BHYC in DMF and DMSO are 2.526 and 2.500 eV, respectively. The optical band gap of BHYC varies from 2.560 to 2.408 eV with increasing molarity. In contrast, the refractive index of BHYC increases from 2.47 to 2.95 with changing molarity. The obtained results show that 3-benzoyl-7-hydroxy coumarin exhibits a semiconductor behavior and it may be an important candidate for many optoelectronic devices, such as diodes, photodiodes and sensors.
