Ultralong room temperature phosphorescence is achieved from amorphous organic materials toward information encryption.
Covalent organic frameworks (COFs) are excellent platforms with tailored functionalities in photocatalysis. There still challenges increasing the photochemical performance of COFs. Therefore, we designed and prepared a series COFs for photocatalytic hydrogen generation. Varying different ratios β-ketoenamine to imine moieties linkages could differ ordered structure, visible light harvesting, bandgap. Overall, β-ketoenamine-linked exhibited much better activity than those having both on...
Uncontrolled cancer cell proliferation, insufficient blood flow, and inadequate endogenous oxygen lead to hypoxia in tumor tissues. Herein, a unique type of hypoxia-responsive human serum albumin (HSA)-based nanosystem (HCHOA) is reported, prepared by cross-linking the hypoxia-sensitive azobenzene group between photosensitizer chlorin e6 (Ce6)-conjugated HSA (HC) oxaliplatin prodrug-conjugated (HO). The HCHOA stable under normal partial pressure with size 100-150 nm. When exposed hypoxic...

Herein, we describe use two enantiomers a 1,4‐benzenedicarboxamide phenylalanine derivative as supramolecular gelators investigate nanofibers adhesion and proliferation in three dimensions. It was found that left‐handed can increase proliferation, whereas right‐handed have opposite...
While manipulating the helicity of nanostructures is a challenging task, it attracts great research interest on account its crucial role in better understanding formation mechanisms helical systems. For supramolecular chirality self-assembly systems, one challenge how to understand origin and inherent information regulated by functionality-oriented stacking modes (such as J- H-aggregation) building blocks. Herein, two-component hydrogels were prepared phenylalanine-based enantiomers achiral...

Herein, a simple approach reported by coassembling small molecules with polyvinyl alcohol (PVA) to afford UOP. These planar conformation present quenched triplet state emission in an excessive stacking solid state. When these PVA, their structures are well confined coassembly films. Such environment leads restricted molecular rotation and vibration,...
Abstract Developing novel lanthanide metal-organic frameworks (Ln-MOFs) to rapidly and reliably differentiate both metal ions in solution volatile organic compounds (VOCs) vapor is highly challenging.

The exhibits notable fingerprint...
Developing molecules with high emission efficiency both in solution and the solid state is still a great challenge, since most organic luminogens are either aggregation-caused quenching or aggregation-induced molecules. This dilemma was overcome by integrating planar distorted structures long alkyl side chains to achieve DAπAD type emitters. A linear diphenyl-diacetylene core charge transfer effect ensure considerable planarity of these excited state, allowing strong dilute (quantum yield up...
