Two new azido bridged 1D polymeric Cu(II) chains, [Cu(L1)(μ1,3-N3)]∞ (1) and [Cu2(L2)2(μ1,1-N3)(μ1,3-N3)]∞ (2) have been synthesized by using two different N2O donor tridentate reduced Schiff base ligands, HL1 = 2-[(2-dimethylamino-ethylamino)-methyl]-4-nitrophenol, HL2 = 2-[(2-diethylamino-ethylamino)-methyl]-4-nitrophenol and both are structurally characterized. Cu(II) ions in both complexes occupy
两个新的叠氮基桥连的1D聚合的Cu(II)链,[铜(L 1)(μ 1,3 -N 3)] ∞(1)和[铜2(L 2)2(μ 1,1 -N 3) (μ 1,3 -N 3)] ∞(2)通过使用两个不同氮已被合成2 ö供体的三齿席夫降低碱配体,HL 1 = 2 - [(2-二甲基氨基-乙基氨基) -甲基] -4-硝基苯酚,HL 2 = 2-[((2-二乙基氨基-乙基氨基)-甲基] -4-硝基苯酚,并且两者都在结构上表征。两种络合物中的Cu(II)离子均占据扭曲的五配角方形锥体。这两种结构形成聚合物链,在1,通过μ 1,3 -N 3 - ,而在2 经由两个μ 1,1 -N 3 -和μ 1,3 -N 3 -桥。配合物的带隙(2.91 eV(1)和2.89 eV(2))表明两条聚合物链都是半导体性的,因此具有在设备中使用的潜力。细节IV进行分析以测量与设备相关的参数,即有效载流子迁移率,渡越时间,载流
