Oxazine ring construction: methods and applications to natural product synthesis
Frontiers of Chemistry in China - Tập 4 - Trang 249-258 - 2009
Xiaobo Wan, Madeleine M. Joullié
Although natural products containing a 1,2-oxazine ring are rare, more examples in this family of natural products have been discovered since trichodermamides A and B were reported in 2003. In addition to their structural novelty, these natural products possess very interesting bioactivities that are strongly dependent on their structures, making them attractive targets for investigating structure...... hiện toàn bộ
A novel NIR violanthrone derivative with high electron-deficiency: effect of fluorescence on dicyanomethylene substitution
Frontiers of Chemistry in China - Tập 5 - Trang 200-207 - 2010
Bo Liu, Duo Fan, Qiong Zhang, Yu Chen, Weihong Zhu
Near infrared (NIR) dyes attracted increasing interests in widely potential applications, such as fluorescent probe and living organism imaging, due to their low background signals from biomolecules, low light scattering and deep penetration, and low-cost excitation light sources. A novel NIR violanthrone derivative (VA-CN) with dicyanomethylene substitution was synthesized and fully characterized...... hiện toàn bộ
A new molecular rectifier device and some research in its processing
Frontiers of Chemistry in China - Tập 1 - Trang 296-299 - 2006
Bijian Lan, Chunming Liu, Xiang Yin, Hua Zhang, Wei Xu, Zhongyi Hua
Organic materials of D-π-A type MR-X (MR-1: p-dimethylaminophenylethenetrica-rbonitrile and MR-2: p-diphenylaminophenylethene tricarbonitrile) were designed and synthesized. The device with a sandwich structure shows good rectificative phenomena. The highest rectification ratio 10000 was achieved in device Cu/MR-1/Ag, and about 100 in other device M/MR-X/M (M: Cu, Ag). It has been found that recti...... hiện toàn bộ
Synthesis of hydrophobic association cationic starch and its flocculation application on containing algae water of Dianchi Lake
Frontiers of Chemistry in China - Tập 3 - Trang 166-171 - 2008
Xiaojun Xu, Xiangyi Liu, Yuming Yang
The hydrophobic formation cationic starch (PSOAMDA) was prepared from starch (St), octadecyl acrylate (OA), acrylamide (AM) and dimethyl diallyl ammonium chloride (DMDAAC) by means of inverse suspension polymerization with redox initiator. Water with algae from Dianchi Lake was tested with PSOAMDA. Results show that when the molar ratio of St: AM: DMDAAC: OA is 4:8:1.5:0.6 and the reaction tempera...... hiện toàn bộ
Applications of HPLC-MS in compound Ilex pubescens extract study
Frontiers of Chemistry in China - Tập 1 - Trang 138-144 - 2006
Yunyun Yang, Chen Hongwei, Ming Zhong, Zhiling Ma, Jiuwei Teng, Dehai Mu
In this paper, high performance liquid chromatography (HPLC) along with mass spectrometry (MS) and HPLC along with a diode array detector (DAD) was used to study the compound Ilex pubescens extract. Two ionization techniques: electro spray ionization (ESI) and atmospheric pressure chemical ionization (APCI) were used in this work. The liquid chromatograms obtained by DAD, total ion chromatograms (...... hiện toàn bộ
Photochromic reactions of 6-hydroxy-5,12-naphthacenequinone and its derivatives bearing methyl or phenyl groups
Frontiers of Chemistry in China - Tập 3 - Trang 400-405 - 2008
Jinghua Yin, Huiqin Lian, Ziyan Zhou, Jiyang Zhao, Xue Wu
Photoisomerizations of 6-hydroxy-5,12-naphthacenequinone and its derivatives bearing methyl and phenyl group were theoretically investigated with density functional theory and ab initio CIS method at the B3LYP 6-31G basis set, respectively. The obtained potential energy curves revealed that a four-state cycle existed in the ground and excited states. It was also found that the activation energy fo...... hiện toàn bộ

Synthesis of Eu(III) and Tb(III) complexes with novel pyridine dicarboxylic acid derivatives and their fluorescence properties
Frontiers of Chemistry in China - Tập 1 - Trang 408-413 - 2006
Ruiren Tang, Zi’er Yan, Cancheng Guo, Yiming Luo
Starting from pyridine-2,6-dicarboxylic acid (DPA), a series of novel pyridine-2,6-dicarboxylic acid derivatives were synthesized. In these compounds, 4-(hydroxymethyl)pyridine-2,6-dicarboxylate (4-HMDPA) and 4-[(bis-carboxymethyl-amino)-methyl]-pyridine-2,6-dicarboxylic acid (4-BMDPA) were used as multifunctional ligands to coordinate with Tb(III) and Eu(III) and the complexes were prepared. The ...... hiện toàn bộ
