Optoelectronic design and charge transport properties of Benzodifuran (BDF) isomers for organic electronic devices: DFT/TD-DFT insights

The primary goal of this work is to provide a comprehensive analysis of the charge transport and optoelectronic characteristics of all the isomers of benzodifuran (BDF) for organic electronic devices in order to suggest qualified materials/candidates for organic photovoltaic devices. Density functional theory (DFT) calculations were performed for all possible isomers of BDF and results are compared with corresponding experimental known isomers. Time Dependent-Density Functional Theory (TD-DFT) is used for the calculation of the absorption and HOMO-LUMO energy levels. To characterize the electronic charge transport state in these isomers, the ionization potentials (IP), reorganization energies (hole and electron), and electron affinities (EA) of all the isomers are investigated. Comparatively, all the BDF isomers are having low electron and hole reorganization energies and hence they can be used in the organic electronic material fabrication.

Automated summary

The aim of this study is to analyze the charge transport and optoelectronic characteristics of all isomers of benzodifuran (BDF) for organic electronic devices, with the goal of identifying suitable materials for organic photovoltaic devices. Density functional theory (DFT) calculations were conducted for all potential BDF isomers and compared with experimental data. Time Dependent-Density Functional Theory (TD-DFT) was used to calculate absorption and HOMO-LUMO energy levels. The ionization potentials (IP), reorganization energies (hole and electron), and electron affinities (EA) of all isomers were investigated to understand their electronic charge transport properties.
