Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

Advanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Strengthened Interfacial Coupling Between Self‐Assembled Monolayers and Bulk Heterojunctions Enables Thermally Stable Organic Solar Cells

Advanced Materials, EarlyView.
Molecularly engineered self‐assembled monolayers (SAMs) featuring extended conjugated terminals facilitate superior interfacial coupling with the organic solar cell active layer. By physically anchoring the local morphology, this design suppresses thermal degradation, allowing devices to operate at 85°C for 150 h before degrading to 90% of their ...

Exploring the Synergy of Combining BINAP and tCzBN Motifs Within Multi‐Resonant TADF Emitters to Enhance OLED Performance

Advanced Optical Materials, EarlyView.
This work presents two MR‐TADF emitters, BINAP‐BN1 and BINAP‐BN2, based on a BINAP core and differing numbers of tCzBN units. Both emitters show similar solution photophysics, but distinct behavior in doped films, where BINAP‐BN1 exhibits higher photoluminescence quantum yield and suppressed aggregation‐induced emission broadening compared to BINAP‐BN2.
