DFT calculations on conjugated organic molecules based on thienothiophene for electronic applications [PDF]

open access: yesE3S Web of Conferences, 2022
We report theoretical studies on the optoelectronic structural properties of five thienothiophene (T) conjugated π conjugates. The geometries, the prediction of the optoelectronic structural properties of the five compounds are studied by calculations of

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

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

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

Structure reactivity analysis for Phenylalanine and Tyrosine

open access: yesCumhuriyet Science Journal, 2021
Phenylalanine (Phe) is one of the amino acids that cannot be produced in the body and must be ingested through diet. Tyrosine (Tyr) is also a non-essential amino acid and can be produced by Phe hydroxylation in the liver when the dietary intake of Tyr is

3-D Multi-Component Reverse Time Migration Method for Tunnel Seismic Data

open access: yesSensors, 2021
Migration imaging is a key step in tunnel seismic data processing. Due to the limitation of tunnel space, tunnel seismic data are small-quantity, multi-component, and have a small offset.
