Synthesis, structures and aggregation-induced emissive properties of copper(I) complexes with 1H-imidazo[4,5-f][1,10]phenanthroline derivative and diphosphine as ligands
摘要:
Reaction of 4-bromo-2-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol (BIPP), chelating diphosphine ligands and [Cu(MeCN)(4)]ClO4 afforded five mononuclear [Cu(BIPP)(PP)]ClO4 (PP = dppe, 1; dppp, 2; bdpp, 3; POP, 4; xantphos, 5) complexes with good phosphorescent emission in the solid state. All the complexes are characterized by elemental analyses, electrospray Ionization mass spectra, H-1 and P-31 NMR spectra and X-ray single crystallography. The photoluminescence quantum yields of complexes 1-5 are from less than 0.010 to 0.262 in the solid state under air atmosphere, which increase with the increasing rigidity of diphosphine ligands and the increasing strength of intermolecular and intramolecular pi center dot center dot center dot pi interactions. The aggregation-induced emission of complexes 4 and 5 at room temperature was investigated. (C) 2015 Elsevier B.V. All rights reserved.

rigid chelating diphosphineligand 9,9-dimethyl-4,5-bis(diphenylphosphino)-9H-xanthene (xantphos) under alkaline conditions in different ratios afforded a series of luminescent binuclear [Cu2(L–H)(xantphos)2]ClO4 (L = L1, 1a; L2, 2a; L3, 3a) and trinuclear [Cu3(L–2H)(xantphos)3]ClO4 (L = L1, 1b; L2, 2b; L3, 3b) complexes. Both trigonal planar and tetrahedral coordination modes of Cu(I) centers were observed

Four new ionic diimine Cu(I) complexes with general formula [Cu(POP)(NN)]BF4 have been synthesized by convenient methods from readily available starting materials. All the complexes were characterized by a range of spectroscopic, electrochemical, and computational techniques and, in the cases of 1, 2, and 3, by single crystal X-ray diffraction. The complexes are emissive in the solid state at ambient

exhibited highly cytotoxic effects on the HCT-116 CSC cell line. This complex was localized in the mitochondria and subsequent mitochondrial dysfunction was observed via MMP alteration and ROS generation on colorectalcancer stem cells. Cell cycle analysis also established the potential of this complex in mediating G2/M phase cell cycle arrest.
在此,我们通过方便的合成方法引入了一系列铱( III )-Cp*-(咪唑并[4,5 - f ][1,10]菲咯啉-2-基)苯酚配合物,它们作为缺氧活性和谷胱甘肽抗性抗癌金属治疗剂。在合成的复合物中,[Ir III (Cp*)(L5)(Cl)](PF 6 ) ( IrL5 ) 复合物在HeLa和Caco-2细胞中表现出最好的细胞选择性、GSH抗性和缺氧效果。IrL5还表现出对 HCT-116 CSC 细胞系的高度细胞毒性作用。该复合物位于线粒体中,随后通过以下方式观察到线粒体功能障碍结直肠癌干细胞的 MMP 改变和 ROS 生成。细胞周期分析还确定了这种复合物在介导 G2/M 期细胞周期停滞方面的潜力。

A boron complex with 4-bromo-2-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenoxide ligand has been synthesized, and its photoluminescence properties in solution and in the solid phase have been examined. The structure of the complex has been determined by X-ray analysis. Non-classical intermolecular interaction (halogen bond) between the bromine and fluorine atoms has been detected in the crystal structure of the complex.
