Ionic multiresonant thermally activated delayed fluorescence emitters for light emitting electrochemical cells

Beilstein Journal of Organic Chemistry, 2022
We designed and synthesized two new ionic thermally activated delayed fluorescent (TADF) emitters that are charged analogues of a known multiresonant TADF (MR-TADF) compound, DiKTa.

Sensing of explosive vapor by hybrid perovskites: Effect of dimensionality

APL Materials, 2020
Lead halide perovskites are very promising materials for many optoelectronic devices. They are low cost, photostable, and strongly photoluminescent materials, but so far have been little studied for sensing. In this article, we explore hybrid perovskites

Indication of current-injection lasing from an organic semiconductor

Applied Physics Express, 2019
In this study, we investigate the lasing properties of 4,4′-bis[(N-carbazole)styryl]biphenyl thin films under electrical pumping. The electroluminescent devices incorporate a mixed-order distributed feedback SiO2 grating into an organic light-emitting ...

Engineering spin propagation across a hybrid organic/inorganic interface using a polar layer

, 2010
Spintronics has shown a remarkable and rapid development, for example from the initial discovery of giant magnetoresistance in spin valves (Baibich, M. N. et al. Giant magnetoresistance of (001)Fe/(001)Cr magnetic superlattices. Phys. Rev. Lett. 61, 2472–

Organic semiconductor photocatalyst can bifunctionalize arenes and heteroarenes

Science, 2019
Two-for-one approach to photoredox In photoredox catalysis, an excited chromophore typically activates a single reactant either by oxidizing or reducing it. Ghosh et al. used a semiconductor catalyst to activate two reactants at once by quenching both an
