Facile synthesis and photodetection characteristics of novel nanostructured triazinyliminomethylpyrano[3,2-c]quinoline-based hybrid heterojunction

• Nanostructured of MTIMPQ was synthesized and well-characterized. • Molecular orbital and structure optimization were achieved by using DFT analysis. • Thin films of MTIMPQ showed direct allowed energy gap of 2.77 eV. • A significant device performance and photodiode characteristics were discussed. This paper attempts to show a correlation between the structure of a novel quinolone derivative and the optical applications of the prepared devices. Currently, condensation reaction of 6-methyl-4,5-dioxo-5,6-dihydro-4 H -pyrano[3,2-c] quinoline-3-carboxaldehyde ( 1 ) with 4-amino-6-methyl-3-thioxo-3,4-dihydro-1,2,4-triazin-5(2 H )-one ( 2 ) gave a new Schiff base; 6-methyl-3-{[(6-methyl-5-oxo-3-thioxo-2,5-dihydro-1,2,4-triazine-4(3 H )-yl)imino]methyl}-4 H -pyrano[3,2- c ]quinoline -4,5(6 H )-dione ( MTIMPQ, 3 ). Debt ( MTIMPQ, 3 ) was inferred based on an accurate spectral element analysis and spectral data. The unique simulation characteristics of the MTIMPQ were achieved by density function theory, DFT and TD-DFT/ B3LYP, using a baseline group 6-311++ G (d, p). Thin films of MTIMPQ were prepared with a low-cost, high-quality topography, examined by scanning electron microscopy and X-ray diffraction. The optical parameters of the films were obtained from the spectrophotometric investigation, which has a great role in the photodiode application. By correlating the fundamental absorption through the visible and UV-spectra with the optical band gap, the value of the energy gap of MTIMPQ is found to be 2.70 eV and confirmed by various methods. Moreover, the J-V properties of the MTIMPQ film-based devices were investigated in the dark and under various illuminations, and distinct response to incident light was obtained, confirming the possibility of using the prepared devices for photodetector applications.
