Transitioning Room-Temperature Phosphorescence from Solid States to Aqueous Phases via a Cyclic Peptide-Based Supramolecular Scaffold.

Aqueous room-temperature phosphorescence (RTP) materials have garnered considerable attention for their significant potential across various applications such as bioimaging, sensing, and encryption. However, establishing a universally applicable method for achieving aqueous RTP remains a substantial challenge. Herein, we present a versatile supramolecular strategy to transition RTP from solid states to aqueous phases.

Amino-Acid-Induced Circular Polarized Luminescence in One-Dimensional Manganese(II) Halide Hybrid.

Circular polarized luminescence (CPL)-active materials attract great attentions owing to their widely applications in 3D optical displays and encrypted transmission. Inspired by the strategies adopted in perovskite based CPL materials, herein, CPL-active hybrids (D)- and (L)-(tert-butyl prolinate)MnCl were successfully prepared by assembling chiral D/L tert-butyl prolinate with manganese (II) chloride. Single crystal structures show the as-formed hybrids possess one-dimensional (1D) structure containing linear chains of face-sharing MnCl octahedral surrounded by prolinate cations.

Highly Efficient Light-Emitting Diodes Based on an Organic Antimony(III) Halide Hybrid.

As low-dimensional lead-free hybrids with higher stability and lower toxicity than those of three-dimensional lead perovskites, organic antimony(III) halides show great application potential in opt-electronic field owing to diverse topologies along with exceptional optical properties. We report herein an antimony(III) hybrid (MePPh ) SbCl with a zero-dimensional (0D) structure, which exhibits brilliant orange emission peaked at 593 nm with near-unity photoluminescent quantum yield (99.4 %).
