Background Introduction Cation-π interactions are electrostatic interactions between cations and electron-rich aromatics. They play a significant role in many biological systems as important driving forces for protein folding, stability, and receptor-ligand interactions/recognition. Currently, most cation-π interactions in proteins are predicted and discovered through statistical analysis conducted by programs and theoretical calculations. Due to the lack … Read more

Original English Title: Mesoporous Carbon Nitride with π‑Electron-Rich Domains and Polarizable Hydroxyls Fabricated via Solution Thermal Shock for Visible-Light Photocatalysis Corresponding Authors: Dr. Jiajia Zhang, Fudan University; Professor Hongbin Lu, Fudan University Authors: Zhimin Zhai (翟志敏), Huihui Zhang (张慧慧) , Fushuang Niu (牛富双), Peiying Liu (刘沛莹) Background Introduction In recent years, with the concept of … Read more

Click the blue text to follow us Abstract Carbon nitride semiconductors are strong candidates for visible light photocatalysts, but the increased Coulombic forces of the singlet Frenkel excitons lead to a narrowed bandgap and weakened exciton dissociation. We overcome this contradiction by co-injecting π-rich electronic domains and polarizable hydroxyl units into mesoporous carbon nitride, achieved … Read more

The superior light/electronic transport capabilities of organic micro-nano crystals show great application prospects in optoelectronic fields such as optical waveguides, optical logic gates, and p-n heterojunctions. However, there is still a lack of in-depth understanding and control over the complex dynamic assembly characteristics of organic molecules. In particular, achieving controlled preparation of π-conjugated molecular micro-nano … Read more

The dynamic characteristics of non-covalent bonds in peptide self-assembly can selectively accommodate guest molecules. However, how to utilize co-assembly to enhance the application defects of host peptides while improving guest molecules remains unclear. In this regard, Professors Wang Weizhi and Niu Guangle from Beijing Institute of Technology aim to realize the supramolecular synergy between the … Read more

Abstract Simultaneous acceleration of radiative and restricted non-radiative decay is crucial for constructing fluorescent materials with high luminous efficiency in the near-infrared second window (NIR-II). This paper proposes a dual strategy of π-extension and deuteration to effectively address this challenging issue. By extending the π-conjugation of aromatic groups and introducing isotopic effects in the AIEgen, … Read more
