Cu‐catalyzed Synthesis of Quinolines by Dehydrogenative Reaction of 2‐Aminobenzyl Alcohol and Ketones: A Combined Experimental and Computational Study
Chemistry - An Asian Journal - Tập 17 Số 22 - 2022
Tuan Minh Ha, Nina Thi Nguyen, Ngoc Huyen Tran, Quoc Viet Ho, Nguyễn Thị Son, Vân Hà Nguyễn, Hien Nguyen, Dang Van Do, Tran Quang Hung, Binh Khanh, Tuan Thanh Dang
AbstractQuinoline derivatives are important moieties in bioactive molecules and advanced materials. However, an efficient strategy to synthesize quinoline derivatives remains challenging. Herein, we describe an efficient and practical method for the synthesis of quinolines by Cu‐catalyzed cyclization of 2‐amino benzyl alcohol with ketones (or secondary alcohols) vi...... hiện toàn bộ
Removal of Acid Orange G Azo Dye by Polycation‐Modified Alpha Alumina Nanoparticles
Chemistry - An Asian Journal - Tập 18 Số 17 - 2023
Thi Hai Yen Doan, Long Dang, Thi Thuy Trang Truong, Thi Ngan Vu, Thanh Son Le, Thi Minh Thu Nguyen, Minh Ngoc Nguyen, Thu Thao Pham, Shin‐ichi Yusa, Tien Duc Pham
AbstractHighly positively charged poly(vinyl benzyl trimethylammonium chloride) (PVBMA) was successfully synthesized with approximately 82% of yield. The PVBMA was characterized by the molecular weight (Mw) of 343.45 g mol−1and the molecular weight distribution, (Đ) of 2...... hiện toàn bộ
Biomass‐Derived Carbon Materials as Prospective Electrodes for High‐Energy Lithium‐ and Sodium‐Ion Capacitors
Chemistry - An Asian Journal - Tập 14 Số 7 - Trang 936-951 - 2019
Subramanian Natarajan, Yun‐Sung Lee, Vanchiappan Aravindan
AbstractBiomass‐derived carbon materials have received special attention as efficient, low‐cost, active materials for charge‐storage devices, regardless of the power system, such as supercapacitors and rechargeable batteries. In this Minireview, we discuss the influence of biomass‐derived carbonaceous materials as positive or negative electrodes (or both) in high‐e...... hiện toàn bộ
A Bifunctional Luminescent Metal–Organic Framework for the Sensing of Paraquat and Fe3+ Ions in Water
Chemistry - An Asian Journal - Tập 14 Số 20 - Trang 3611-3619 - 2019
Hongjuan Chen, Fan Peng, Xingxin Tu, Hui Min, Xianyong Yu, Xiaofang Li, Ju‐Lan Zeng, Shaowei Zhang, Peng Cheng
AbstractThe hydrothermal reaction of Zn2+ ions with a mixture of two ligands, Hcptpy and H3btc (Hcptpy=4‐(4‐carboxyphenyl)‐2,2′:4′,4′′‐terpyridine; H3btc=1,3,5‐benzenetricarboxylic acid), led to the formation of a 3D metal–organic framework (MOF) with 1D channels, [Zn2(cptpy)(btc)(H...... hiện toàn bộ
Triazole: the Keystone in Glycosylated Molecular Architectures Constructed by a Click Reaction
Chemistry - An Asian Journal - Tập 2 Số 6 - Trang 700-708 - 2007
Alessandro Dondoni
AbstractThe copper(I)‐catalyzed modern version of the Huisgen‐type azide–alkyne cycloaddition to give a 1,4‐disubstituted 1,2,3‐triazole unit is introduced as a powerful ligation method for glycoconjugation. Owing to its high chemoselectivity and tolerance of a variety of reaction conditions, this highly atom‐economic and efficient coupling reaction is especially u...... hiện toàn bộ
Graphitic C3N4 Decorated with CoP Co‐catalyst: Enhanced and Stable Photocatalytic H2 Evolution Activity from Water under Visible‐light Irradiation
Chemistry - An Asian Journal - Tập 12 Số 3 - Trang 361-365 - 2017
Hui Zhao, Pingping Jiang, Wen Cai
AbstractIn this work, graphitic C3N4 decorated with a CoP co‐catalyst (g‐C3N4/CoP) is reported for photocatalytic H2 evolution reaction based on two‐step hydrothermal and phosphidation method. The structure of g‐C3N4/CoP...... hiện toàn bộ
A Diketopyrrolopyrrole‐Based Colorimetric and Fluorescent Probe for Cyanide Detection

Synthesis of Black Phosphorus Quantum Dots with High Quantum Yield by Pulsed Laser Ablation for Cell Bioimaging
Chemistry - An Asian Journal - Tập 13 Số 14 - Trang 1842-1846 - 2018
Xin Ren, Fang Zhang, Xiaoling Zhang
AbstractBlack phosphorus quantum dots (BPQDs), with an average diameter of about 6 nm and a height of about 1.1 nm, are successfully synthesized by means of a pulsed laser ablation (PLA) method in isopropyl ether (IPE) solvent. The photoluminescence PL quantum yield of the as‐prepared sample is as high as 20.7 %, which is 3 times that of BPQDs prepared by means of ...... hiện toàn bộ
Template‐Directed In Situ Polymerization Preparation of Nanocomposites of PEDOT:PSS‐Coated Multi‐Walled Carbon Nanotubes with Enhanced Thermoelectric Property
Chemistry - An Asian Journal - Tập 10 Số 1 - Trang 149-153 - 2015
Zhuang Zhang, Guangming Chen, Hanfu Wang, Xin Li
AbstractA template‐directed in situ polymerization preparation of nanocomposites of poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)‐coated multi‐walled carbon nanotubes (MWCNTs) with greatly enhanced thermoelectric property is presented. The results reveal that monomeric 3,4‐ethylenedioxythiophene was successfully polymerized, enwrapping the sur...... hiện toàn bộ
