    Fluorescence Chemosensor for HSO4 − Ion Based on Pyrrole-Substituted Salicylimine Zn2+ Complex: Nanomolar Detection
    摘要:
    我们合成了一种新型吡咯取代水杨亚胺锌 (II) 离子络合物,并对其阴离子结合亲和力进行了评估。在 CH3OH:H2O (70:30, v/v) 溶剂体系中,探针 4 对 HSO4 - 的选择性高于其他阴离子。加入 HSO4 - 后,4 的发射强度会被淬灭。探针 4 对 HSO4 - 具有高度选择性,检测限为 40 nm。光诱导电子转移(PET)是造成观察到的变化的原因。通过吸光度曲线的比率变化,进一步验证了 4 与 HSO4 - 的结合亲和力。

  • A highly selective and sensitive fluorescent turn-on chemosensor for Al<sup>3+</sup> based on a chromone Schiff base
    作者:Chunjiao Liu、Zhengyin Yang、Mihui Yan
    DOI:10.1080/00958972.2012.726987
    日期:2012.11.10
    A Schiff-base fluorescent sensor, 7-methoxychromone-3-carbaldehyde-(3′,4′-dimethyl)pyrrole hydrazone (MCPH), was synthesized. The new sensor showed high selectivity for Al3+ over other metal ions examined in acetonitrile. Upon binding Al3+, a significant fluorescence enhancement with a turn-on ratio over 101-fold was triggered. The detection limit of MCPH for Al3+ was 2.5 × 10−7 mol L−1.

    A new ligand H3L, 4-[(3,4-dimethylpyrrole-2-carbonyl)hydrazono](phenyl)methyl}-3-methyl-1-phenylpyrazol-5-ol and its three transition metal complexes, M(H2L)OAc·H2O (M=Cu, Ni), Zn(H2L)2 have been synthesized and fully characterized on the basis of ESI-MS, elemental analyses, molar conductivities, IR spectra and 1H-NMR. In addition, their antioxidative activities have been investigated by spectrophotometer measurements. The experimental results show that the complexes have higher activity in the suppression of O2·− and ·OH than the free ligand.

  • Crystal structures, DNA-binding and cytotoxic activities studies of Cu(II) complexes with 2-oxo-quinoline-3-carbaldehyde Schiff-bases
    作者:Zeng-Chen Liu、Bao-Dui Wang、Bo Li、Qin Wang、Zheng-Yin Yang、Tian-Rong Li、Yong Li

    Three novel 2-oxo-quinoline-3-carbaldehyde Schiff-bases and their Cu(II) complexes were synthesized. The molecular structures of Cu(II) complexes were determined by X-ray crystal diffraction. The DNA-binding modes of the complexes were also investigated by UV vis absorption spectrum, fluorescence spectrum, viscosity measurement and EB-DNA displacement experiment. The experimental evidences indicated that the ligands and Cu(II) complexes could interact with CT-DNA (calf-thymus DNA) through intercalation, respectively. Comparative cytotoxic activities of ligands and Cu(II) complexes were also determined by MTT [3-(4,5-dimethyl-2-thiazoyl)-2,5-diphenyl-2H-tetrazolium bromide] and SRB (sulforhodamine B) methods. The results showed that the three Cu(II) complexes exhibited more effective cytotoxic activity against HL60 cells and HeLa cells than corresponding ligands. Also, CuL3 showed higher cytotoxic activity than CuL1 and CuL2 (C) 2010 Elsevier Masson SAS. All rights reserved.
