【摘要】 平面四边形多吡啶铂(Ⅱ)配合物因独特配位几何和丰富光物理性质及在材料科学的应用前景而被广泛研究[1,2]。应用2,2′-联吡啶-6-甲酸甲酯和4,4′-二甲基-2,2′-联吡啶-6-甲酸甲酯制得3个铂(Ⅱ)配合物1~3。单晶衍射结果表明,4,4′-二甲基-2,2′-联吡啶-6-甲酸甲酯配体的甲酸甲酯基团在铂(Ⅱ)离子作用下发生水解并生成甲酸根,原位产生的4,4′-二甲基-2,2′-联吡啶-6-甲酸根的2个N原子和1个O原子以及三苯基膦的1个P原子与铂(Ⅱ)离子配位,形成一变形平面四边形。配合物1~3常温下表现固态荧光发射性质,受联吡啶取代基和辅助配体影响。这些研究结果为设计合成多吡啶铂(Ⅱ)配合物光功能分子材料提供了新的设计思想和合成途径。更多还原

【Abstract】 Square-planar Pt(Ⅱ) multi-pyridyl complexes have been widely investigated due to their special geometry,rich photophysical properties,and promising applications in materials science.Complexes 1–3 have been synthesized by using 6-methoxycarbony-2,2′-bipyridine and 6-methoxycarbony-4,4′-dimethyl-2,2′-bipyridine.It is revealed that complex 3 gives a distorted square-planar N2OP arrangement,in which the carboxylate anion is generated for the hydrolysis of the methoxycarbony group mediated by the Pt(Ⅱ) cation.Complexes 1–3 show a solid emission at RT,which is affected by the substituents of the bipyridyl ring and the ancillary ligand.The results herein provides a new insight and approach for preparing photofunctional molecular materials of Pt(Ⅱ) multi-pyridyl complexes.更多还原
