In the current work, the structural and optical properties of thermally evaporated 3-(2-Benzothiazolyl)-7-(diethylamino) coumarin [Coumarin 6 (C6)] thin films on a pre-cleaned quartz substrate were studied as a function of the annealing temperature The influence of annealing on the structural, morphol., and mol. structures was investigated by x-ray diffraction (XRD), at. force microscopy (AFM), and Fourier transform IR (FTIR) spectroscopy, resp. The XRD and AFM results confirmed that the as-deposited and annealed films have nanostructural features (30.96-45.34 nm). Also, the increase in roughness of the C6 thin film surface resulted from particle agglomeration and coalescence. Optical constants of C6 thin films were derived from the transmittance T(λ) and reflectance, R(λ) measurements in the spectral range of 200-2500 nm. Anal. of the optical absorption coefficient data indicates that the type of electronic transition in these films is an indirect allowed transition. The estimated optical band gap was decreased from 2.12 eV to 2.01 eV as the annealing temperature was increased. Dispersion and dielec. parameters were determined as functions of the annealing temperature Lastly, nonlinear optical parameters such as the third-order nonlinear susceptibility, χ(3) and nonlinear refractive index, n(2) were estimated and influenced by annealing temperature The optical properties of C6 thin films were showed that C6 thin films would be used in a wide range of photonic applications Graphical Abstract: [graphic not available: see fulltext]. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Application In Synthesis of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one).
3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. Thiazoles in peptides or their ability to bind proteins, DNA and RNA has led to many synthetic studies and new applications. The nitrogen in thiazole is sp2 hybridized and the lone pair of electrons localized on the nitrogen is less reactive due to increased aromatic character and decreased basicity. It is protonated and alkylated/acylated at nitrogen forming hydrochloride and quaternary thiazolium salt.Application In Synthesis of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one
