| 1 | Hierarchical porous cellulose/lanthanide hybrid materials as luminescent sensor显示文摘Photoluminescent hybrid materials containing carboxymethyl cellulose and lanthanide ions(Eu3+, Tb3+)were prepared by a facile method under ambient conditions. Lanthanide ions were covalently grafted to the cellulose framework through coordination with the carboxylic groups of the cellulose. Hybrid materials were fabricated as hydrogel and aerogel. As shown by SEM and pore parameters, aerogel materials which were obtained by supercritical CO_2 drying show hierarchical porous structure. The photoluminescence spectrum of the hybrid materials shows the characteristic red emission of Eu3+ ion and green emission of Tb^(3+). Further luminescent investigations reveal that these hybrid materials can detect Fe^(3+) with relative selectivity and high sensitivity, which suggests that the hybrid materials could be a promising luminescent probe for selectively sensing Fe^(3+) ion. | Wentao Fan Jiaojiao Du Junfeng Kou Zeyu Zhang Fengyi Liu | 2018 | Journal of Rare Earths2018，36，10： | 5 |
| 2 | Synthesis, DNA-binding and photocleavage studies of ruthenium(Ⅱ) complexes [Ru(btz)_3]^(2+) and [Ru(btz)(dppz)_2]^(2+)显示文摘Two new ruthenium(Ⅱ) complexes, [Ru(btz)3](ClO4)2 (1) and [Ru(btz)(dppz)2](ClO4)2 (2) (btz = 4,4′-bithi-azole, dppz = dipyrido[3,2-a:2′,3′-c]phenazine), have been synthesized and characterized by elemental analysis, 1H NMR, ES-MS and X-ray crystallography. The DNA binding behaviors of two complexes have been studied by spectroscopic and viscosity measurements. The results suggest that complex 1 binds to CT-DNA via an electrostatic mode, while complex 2 via an intercalative mode. Under irradiation at 365 nm, both complexes were found to promote the cleavage of plasmid pBR 322 DNA from supercoiled form Ⅰ to nicked form Ⅱ. The mechanism studies reveal that singlet oxygen 1O2 and hydroxyl radical (OH-) play a significant role in the photocleavage process. | YU HuiJuan, HUANG ShuMei, KOU JunFeng, LI LvYing, JIA HaiNa, CHAO Hui & JI LiangNian MOE Laboratory of Bioinorganic and Synthetic Chemistry, School of Chemistry and Chemical Engineering, Sun Yat-Sen University, Guangzhou 510275, China | 2009 | Science China Chemistry2009，52，9： | 4 |
| 3 | Synthesis,crystal structures,electrochemical and spectroscopic properties of ruthenium(Ⅱ) complexes containing diamino-1,3,5-triazine derivatives显示文摘Three Ru(Ⅱ) complexes [Ru(bpy)2(1-IQTNH)](ClO4)2 (1), [Ru(bpy)2(2-QTNH)](ClO4)2 (2) and [Ru(bpy)2(3-IQTNH)](ClO4)2 (3) (bpy = 2,2′-bipyridine, 1-IQTNH = 6-(isoquinolin-1-yl)-1,3,5-triazine-2,4-diamine, 2-QTNH = 6-(quinolin-2-yl)-1,3,5-triazine-2,4-diamine, 3-IQTNH = 6-(isoquinolin-3-yl)-1,3,5-triazine-2,4-diamine) have been synthesized and characterized by elemental analysis, 1H NMR spectroscopy, electrospray ionization mass spectrometry and X-ray crystallography. The electrochemical and spectroscopic properties of the complexes differ from those of [Ru(bpy)3]2+ owing to the structural differences between the ligands and their complexes. | CHEN Yu, XU WenChao, KOU JunFeng, WEI XuHui, YU BoLe, CHAO Hui & JI LiangNian MOE Laboratory of Bioinorganic and Synthetic Chemistry, School of Chemistry and Chemical Engineering, Sun Yat-Sen University, Guangzhou 510275, China | 2010 | Science China Chemistry2010，53，10： | 1 |
