Kang’s work entitled “Suppressing phase disproportionation in quasi-2D perovskite light-emitting diodes” has been published in Nature Communications. Congratulations!
We demonstrate that extending the π-conjugation length and increasing the cross-sectional area of the organic semiconducting ligand enables perovskite thin films with dramatically suppressed ion transport, narrowed phase distributions, reduced defect densities, and enhanced radiative recombination efficiencies. Consequently, we achieved efficient and stable deep-red light-emitting diodes with a peak EQE of 26.3% and a half-life of ~220 h under a constant current density of 0.1 mA/cm2. Read the story here.

Jeonghui Kim joins our group as a first-year graduate student. Jeonghui receives her BS and MS in Chemical Engineering from Inha University. She is interested in both halide perovskite and polymer materials. Welcome to the group!
Yuanhao passes his PhD qualifier exam. Congratulations!
Zitang (Tim)’s work entitled “Side-Chain Control of Topochemical Polymer Single Crystals with Tunable Elastic Modulus” has been published in Angew. Chem. Int. Ed. Congratulations!
In this work, we report a systematic study on the side chain functionalization of the bis(indandione) derivative system that can be polymerized under visible light. Precisely engineered side chains help organize the monomer crystals in a one-dimensional fashion to facilitate polymerization and improve mechanical properties. Read the story here.
