Highly Active Nodules on Concave–Convex Channel Walls of Covalent Organic Frameworks for Photocatalytic Hydroperoxide Production

Xinhe Ye, Bingxian Chu, Quan Zuo, Hao Nian et autres

ABSTRACT Covalent organic frameworks (COFs) are promising photocatalysts for hydrogen peroxide (H 2 O 2 ) production. However, the smooth channels of traditional COFs exhibit weak charge density gradients and lack highly electron‐localized sites for O 2 adsorption, thereby showing unsatisfactory photocatalytic …

Acid/base responsive pseudo[3]rotaxanes from amine naphthotubes and bis-pyridinium/isoquinolinium guests

Li‐Shuo Zheng, Hao Nian, Song-Meng Wang, Yanfang Wang et autres

-H⋯O hydrogen bonds between the two hosts are responsible for the positive cooperativity during the formation of pseudo[3]rotaxanes. Moreover, intermolecular charge-transfer interactions between the electron-rich host and the electron-poor guests were observed. The pseudo[3]rotaxanes showed pH-controllable association/dissociation processes with naked-eye color changes …
