Abstract
Abstract
Azole derived products acquired significant consideration in everyday life based on their improved biological potential to the semiconducting substances. The research focused in-depth within pyrazol, and oxazole compounds 1–4 concerning charge transport, structural, optical as well as electronic properties. The density functional theory (DFT) along with time-dependent DFT were used for the optimization of their ground state geometries and excitation energies. We also investigated the molecule’s electron coupling constants (|V
RP|) as well as electron injection (ΔG
inject) values. For better understanding, charge transport and electronic characteristics were performed through quantum chemical computations. The |V
RP| and ΔG
inject values of pyrazole, as well as oxazole molecules, exhibited that these compounds could be competent for dye-sensitized solar cell applications. The pyrazole higher diagonal band gap enlightening these might have enhanced fill factor (FF) along with short-circuit current density (J
sc
). We have also explored the electron injection, energy level offset, dissociation of excitons, and band alignment of studied compounds to shed light on the functionality of these compounds for photovoltaic and semiconductor device applications.

Abstract
The isoxazole derivatives gained significant attention in our daily life from better biological activity to the semiconducting materials. This study deals in depth investigation of two isoxazole derivatives, i.e. 2-[(E)-(3,4-Dimethylisoxazol-5-yl)iminomethyl]phenol (1) and 1-[(E)-(3,4-Dimethylisoxazol-5-yl)iminomethyl]-2-naphthol (2) with respect to the geometric, charge transport, optoelectronic and nonlinear optical properties by density functional theory (DFT) and time-dependent DFT. The comprehensible intra-molecular charge transfer (ICT) was conceived from HOMOs to LUMOs. Strength of the electron donor groups was investigated on the absorption wavelengths, emission wavelengths, ionization potentials (IPs), electron affinities (EAs), total/partial densities of states and structure-property relationship. The smaller hole reorganization energies and superior transfer integrals of isoxazole derivatives (1 and 2) than the electron ones are leading to higher hole intrinsic mobility values as compared to the electron mobility exhibit that these systems would be good hole transport contenders. The first hyperpolarizability values are about 19 and 21 times larger than that of urea suggesting that 1 and 2 can also be considered as potential contestants for NLO applications as well.

Abstract
2,6-Di(1H-benzo[d]imidazol-2-yl)pyridine (DBIP) was synthesized. The single-crystal structure of DBIP was resolved. DBIP-based OLED was fabricated. The electroluminescence for the device corresponds to a pure white emission. In addition, thermal stability, UV-vis, photoluminescence and electrochemical behaviors of DBIP were investigated as well.
