Single excitation energies obtained from the ensemble HOMO-LUMO gap: exact results and approximations [PDF]

open access: yes, 2022
In calculations based on density functional theory, the "HOMO-LUMO gap" (difference between the highest occupied and lowest unoccupied molecular orbital energies) is often used as a low-cost, ad hoc approximation for the lowest excitation energy. Here we

Excited-state energy component analysis for molecules - Why the lowest excited state is not always the HOMO-LUMO transition [PDF]

open access: yes, 2023
The ability to tune excited-state energies is crucial to many areas of molecular design. In many cases this is done based on the energies of the highest occupied (HOMO) and lowest unoccupied (LUMO) molecular orbitals.

Cyano-Substituted Perylene Diimides with Linearly Correlated LUMO Levels

open access: yes, 2016
A series of nonbay region cyano-substituted tetrachloro­perylene diimides with tunable LUMO energy levels from −4.21 to −4.64 eV were developed. The excellent linear correlation between LUMO energy levels and the number of cyano groups indicated that the

Synthesis and Characterization of Benzodithiophene (BDT) Quinoid Compounds as a Potential Compound for n-Type Organic Thin-Film Transistors (OTFT)

open access: yesJurnal Kimia Sains dan Aplikasi, 2020
Two potential compounds as an n-Type organic thin-film transistor (OTFT) from benzodithiophene (BDT) derivatives have been synthesized and characterized. BDT was chosen as the core because it has π-conjugated bonds, rigid structures, and planar.
