Hydrogen-bond engineered supramolecular bismuth halides for flexible X-ray imaging without geometric distortion

Metformin Spacer Conformation Is a Structure-Directing Element in a 2D Perovskite with Strong X-ray Response

Direct X-ray detection in two-dimensional (2D) hybrid metal-halide perovskites is dictated by the interplay between organic spacer chemistry, crystal structure, and charge transport. Among these materials, the metformin (MF2+)-based perovskite MFPbI4 has recently emerged as a promising X-ray detector, exhibiting high...

Isotopological Modulation of Entanglement in 3D Covalent Organic Frameworks Unlocks a Fully Open Catalytic Architecture.

Rational control over structural entanglement in three-dimensional covalent organic frameworks (3D COFs) is essential for optimizing catalytic-site accessibility and substrate transport in heterogeneous catalysis. However, conventional thermodynamically governed crystallization often produces interpenetrated architectu...

Solvent‐Induced Structural Modulation in Nanoscale Covalent Organic Frameworks Enables High‐Performance NO2 Sensing

ABSTRACT Covalent organic frameworks (COFs) offer exceptional structural and functional tunability, enabling performance optimization in separation, catalysis, and sensing applications. Here, we report a solvent‐induced strategy for inducing structural disorder in porphyrin‐based COF nanoparticles (nanoCOFs) synthesize...

Polymeric Templates Enhancing the Quality of Two-dimensional Covalent Organic Framework Films Prepared on Water Surface

Customized Flexibility in Soft Porous Crystals With Coupled Dynamics for Matching Separation of Light Hydrocarbons.

Soft porous crystals exploit adaptive structural dynamics for molecular recognition, yet their elusive nature hinders the fundamental understanding of rational design and reliable applications. Here, the correlation dynamics intrinsic to layered M(pbe)-α (M = Co2+, Zn2+, Cu2+), transmitting from mono-vertex to strained...

Amorphous Self-Assembled Molecule with Distorted Backbone Suppresses Aggregation for Highly Efficient Inverted Perovskite Solar Cells

Self-assembled molecules (SAMs) commonly employed in inverted perovskite solar cells (PSCs) are plagued by severe molecular aggregation that leads to non-uniform substrate coverage, consequently increased interfacial charge recombination and compromised operational stability. To overcome this limitation, we rationall...
