Thermal and photochemical reactions of dihydrodiazines

open access: yes, 1979
This thesis describes the results of an investigation into the thermal and photochemical reactivity of dihydrodiazines.In order to prepare the title compounds the diazines and some phenyldiazines are treated with phenyllithium in ether, yielding adducts ...

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

A DFT Study on the Radical Structures and HOMO-LUMO Analysis of Azathioprine

open access: yesErzincan Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
Azathioprine (Imuran) is used for to treat of numerous debilitating skin diseases. Azathioprine is an immunosuppressive antimetabolite used to prevent the body from rejecting a transplanted kidney. By means of EPR spectroscopy, this compound was studied experimentally before. But experimental searchers were only able to determine g value.

Machine Learning Accelerated Computational Design of Bio‐Inspired Catalysts in the Nitrogen Reduction Reaction

open access: yesAdvanced Materials, EarlyView.
We introduce a computational workflow that combines quantum chemical calculations and machine learning techniques to predict the catalytic performance of a wide range of catalysts in the nitrogen reduction reaction (NRR). The analysis of the trained models provides insights into the complex structure–activity relationship in experimental catalytic ...

Evaluation of various density functionals for predicting the electrophosphorescent host HOMO, LUMO and triplet energies

open access: yes, 2014
Design of phosphorescent hosts for deep blue emitter with suitable electronic states for high efficiency electrophosphorescent light emitting diodes is often carried out by using wet-lab techniques and trial and error.

Linker‐Engineered Dimeric Acceptors Afford Efficient Organic Photocatalytic Hydrogen Evolution via Tailored Nanomorphology for Long‐Lived Charge Accumulation

open access: yesAdvanced Materials, EarlyView.
We developed a new series of monomeric (MY) and dimeric acceptors incorporating unfused (DY1) and fused (DY2) linkers, which establish a controlled self‐aggregation trend of MY > DY2 > DY1. The DY2‐based system yields a bulk‐heterojunction nanoparticle morphology that appears to balance phase separation and interfacial accessibility, consistent with ...

Substituent and Conjugation Effects on the Homo-Lumo Bandgaps of 9-Fluorenones, 9-Fluorenylidenes, and Related Derivatives

open access: yes, 2010
Fluorenones and related derivatives have been explored in many studies for the development of organic-based semiconducting materials. In such materials, the size of the bandgap and the relative energy levels of the highest-energy occupied molecular ...

Steric Coordination Modulated Iodine Chemistry With Four‐Electron Conversion for Zinc‐Iodine Batteries

open access: yesAdvanced Materials, EarlyView.
A dual‐additive electrolyte strategy is developed to address the hydrolysis of I+ in the aqueous electrolytes. The steric‐hindrance effect of TES− effectively shields I+ from nucleophilic attacks by hydroxyl groups, facilitating the reversible I−/I0/I+ conversion with four‐electron transfer.
