ORGANIC CHEMISTRY FRONTIERSOuyang, Wensen Liu, Bairong He, Yi Wen, Yanmei Gao, Yang Huo, Yanping Chen, Qian Li, Xianwei  出版年:2022
A switchable C-H alkylation and N-alkylation with great chemo- and site-selectivity enabled by N-nitroso anilines was developed, affording functionalized anilines, hydrazines and heterocycles. The exploration of strain-r...
Solvent-free pyrolysis synthesis of solid-state fluorescent carbon dots: Optical properties and latent fingerprint imaging
DIAMOND AND RELATED MATERIALSLuo, Kun Li, Wanjun Luo, Xiaoke Kang, Xinhuang Wen, Yanmei  出版年:2024
Carbon dots (CDs) have garnered significant attention due to their remarkable optical properties and low cytotoxicity. However, most studies on CDs have predominantly focused on their fluorescence behavior in solution, b...
Synthesis of graphene quantum dots with temperature-sensitive properties from sea rice for rapid and highly selective detection of 4-nitrophenol
DIAMOND AND RELATED MATERIALSLuo, Kun Luo, Xiaoyu Wu, Yulian Liang, Zhibin Kang, Xinhuang Wen, Yanmei  出版年:2023
The green transformation of biomass materials into carbon nanomaterials with high application value has always been of great interest. In this study, we successfully synthesized temperature-sensitive and narrow-size dist...
Transition-Metal-Free Borylation of Alkynes and Alkenes
CHEMISTRYSELECTDeng, Chun M. Ma, Yi F. Wen, Yan M.  出版年:2018
The transition metal-free method for borylation of alkynes and alkenes with bis(pinacolato)diboron has been developed, producing the correspondent organoborons under mild reaction conditions. This reaction was an efficie...
Self-doping synthesis of iodine-carbon quantum dots for sensitive detection of Fe(iii) and cellular imaging
NEW JOURNAL OF CHEMISTRYLuo, Kun Luo, Wenyi Liang, Zhibin Li, Yubin Kang, Xinhuang Wu, Yulian Wen, Yanmei  出版年:2022
Carbon quantum dots (CQDs) are carbon nanomaterials with fluorescent properties. Due to their unique structure and optical properties, CQDs have become a research hotspot in recent years. In this paper, iodine-doped CQDs...
Synthesis of palladium supported on mesoporous hydroxyapatite from oyster shells for use as efficient, green, and recyclable catalyst for Heck reactions
JOURNAL OF NANOPARTICLE RESEARCHLuo, Wenyi Wen, Yanmei Lin, Xianjia Wu, Yulian Xie, Xiangyu Kang, Xinhuang  出版年:2022
Homogeneous catalysts exhibit several drawbacks, such as high cost, difficulty of separation, and non-recyclability, necessitating the development of heterogenous catalysts to solve these problems. Hydroxyapatite (HAP) c...
Catalytic synthesis of benzimidazolyl-phenoxyacetic acid <i>O</i>-acetyllactosyl saccharide esters by DMAP/Et<sub>3</sub>N and antiviral activity against TMV
JOURNAL OF CHEMICAL RESEARCHChen, H Huang, SQ Wen, YM Li, SD  出版年:2005
Benzimidazolyl-phenoxyacetic acid O-acetyllactosyl saccharide esters were synthesised in good yields at room temperature using DMAP/Et3N. The compounds show better antiviral activity against tobacco mosaic virus (TMV).
Photochromic dithienylethene based on porphyrin for a nondestructive information processing
JOURNAL OF PORPHYRINS AND PHTHALOCYANINESYu, Chuanming Wen, Yanmei Kang, Xinhuang  出版年:2018
