“…The importance of coumarins in the field of optoelectronics [1][2][3], fluorescent markers for proteins [4], cellular imaging [5] and lasers [6] and optical whitening [7] is well documented in the literature. The typical absorbance and emission wavelengths of coumarin derivatives lies in the blue-green region (400-520 nm) and the molecules of coumarin class are known to be highly fluorescent [8] with moderate to good quantum yields [9].…”

The red emitting dyes were synthesized by employing coumarin core as a donor and boron-bonded coumarin as an acceptor. 7-(N,N-Diethylamino)-coumarin 3-aldehyde was reacted with 3-acetyl-4-hydroxy-coumarin, 7-(N,N-diethylamino)-3-acetyl-4-hydroxy-coumarin and 3-acetyl-4-hydroxy-1-methyl-quinolone to form the corresponding chalcones. The synthesized chalcones were though red shifted as compared to the parent coumarin, and were not emitting in red region. The BF2-complexation was used as a tool to introduce a red shift in the molecules. The BF2-complexes synthesized were found to be red emitting and show higher one photon absorption cross section. The solvatochromism shown by these dyes was studied in the light of solvent polarity parameters. DFT calculations were used to understand the photophysical properties of the synthesized dyes. NLO properties of the dyes were estimated by solvatochromic and computational methods. All the molecules synthesized were characterised with the HRMS and NMR spectral Analysis.

“…In addition, the electrical parameters of the metal/semiconductor interface may control the contact resistance. [9][10][11][12] Therefore, the structural and chemical characteristics of organic materials and metal/semiconductor interface are important for the charge carrier transport in organic material based Schottky diodes. [13] Organic compounds containing benzaldehyde as a substitution are found in many plants in combined or non-combined forms.…”

Four benzaldehyde derivatives [ALD‐1: compound (1), ALD‐2: compound (2), ALD‐5: compound (3), ALD‐6: compound (4)] were taken to investigate their optical band gap by UV‐vis spectroscopy. Semiconducting devices were fabricated using these compounds to study their electrical properties. The current‐voltage (I–V) characteristics graph was obtained. Furthermore, the diode parameters were extracted by conventional methods to analyze the charge transport mechanism. From the dielectric study, a low dielectric constant was observed. Moreover, each compound‘s mobility and transit time were derived to compare the device performance of benzaldehyde derivatives.

Highlights New coumarin derivative (4-[( pyridin -3- ylmethyl ) amino ]−2 H -chromen-2-one) (L TA ) was synthesized and characterized by spectroscopic techniques. The ligand was characterized by single-crystal X-ray diffraction method and optimized by DFT method. The chemical reactivity, kinetic and thermodynamic parameters of L TA were calculated. The interaction of L TA with SARS-CoV-2/Main protease (Mpro) was studied. The docking simulation showed active L TA molecule with the ability to inhibit SARS-CoV-2.
