Low‐Temperature Cross‐Linkable Small Molecules for Fully Solution‐Processed OLEDs

Abstract

Cross-linkable hole-transporting, host, and electron-transporting materials with a new cross-linking group, uracil, are designed and synthesized. These compounds exhibited good solubility in common organic solvents and excellent solvent resistance after cross-linking at a low temperature of 120 °C. The OLED was fabricated by all-solution processing using cross-linkable synthetic compounds, except for the electrodes. This device exhibited a current efficiency of 39.2 cd A and a power efficiency of 15.3 lm W .

Design and Optimization of Novel Competitive, Non-peptidic, SARS-CoV-2 Mpro Inhibitors

“…It was at this stage that we ran into synthetic difficulties. We initially envisaged that we would be able to carry out a Chan–Lam coupling between 3-pyridyl boronic acid 14 and preferably the desired N3 of our uracil derivative, 11 . Unfortunately, however, the required selectivity was not attained under these conditions, and in fact, we obtained a slight preponderance of the undesired reaction at N1 (as determined by X-ray crystallography).…”
