Unveiling the Actual Catalytic Sites in Nanozyme-Catalyzed Oxidation of o-Phenylenediamine

Lu Cheng, Fengxia Wu, Haibo Bao, Fenghua Li, Guobao Xu, Yongjun Zhang, Wenxin Niu

Summary: Nanozymes offer significant advantages over natural enzymes and have diverse applications. The oxidation of OPD by nanozymes is a standard protocol for determining their activities, but the mechanism of this process differs from natural enzymes. The study found that OPD polymerization on nanozyme surfaces alters their intrinsic properties, impacting the reliability of OPD-based colorimetric methods for activity determination.

Electron-phonon coupling-assisted universal red luminescence of o-phenylenediamine-based carbon dots

Boyang Wang, Zhihong Wei, Laizhi Sui, Jingkun Yu, Baowei Zhang, Xiaoyong Wang, Shengnan Feng, Haoqiang Song, Xue Yong, Yuxi Tian, Bai Yang, Siyu Lu

Summary: The photoluminescence mechanism of carbon dots (CDs) remains unclear due to their complex core-shell structure and variety of surface functional groups. In this study, we prepared six different oPD-based CDs and found that they had almost the same PL emission and absorption spectra after purification. Structural and spectral characterization revealed similar carbon core structures but different surface polymer shells. Single-molecule PL spectroscopy confirmed that the multi-modal emission of those CDs originated from the transitions of different vibrational energy levels of the same PL center in the carbon core. Theoretical calculations provided insights into the potential polymerization mode and carbon core structure. Additionally, the phenomenon of spectral splitting of single-particle CDs was observed at low temperature, indicating their unique properties as both organic molecules and quantum dots.

Sima Pourghasem, Farid Moeinpour, Fatemeh S. Mohseni-Shahri

Summary: Copper(II)@polyimide linked covalent organic frameworks (Cu@PI-COF) were successfully used for the efficient synthesis of 1,5-benzodiazepines via 1,2-diaminobenzene, aromatic aldehydes, and dime-done under solvent-free and microwave assisted conditions. The three-component condensation reaction provides safe operations, low pollution, quick access to products, and an easy setup due to the application of solvent-free conditions and microwave irradiation. The catalyst can be reused multiple times without any loss of activity.
