shape-controlled synthesis of HgS nanoparticles (NPs) in which Hg(II) dithiocarbamate complexes are used as the starting materials. The precursor complexes bis(4-benzhydrylpiperazine-1-carbodithioate-κ2 S,Sʹ)mercury(II), bis(4-benzylpiperazine-1-carbodithioate-κ2 S,Sʹ)mercury(II), bis(4-hydroyethylpiperazine-1-carbodithioate-κ2 S,Sʹ)mercury(II), bis(4-benzylpiperidine-1-carbodithioate-κ2 S,Sʹ)mercury(II) and propane-1
摘要采用单一来源的前驱体策略,以Hg(II)二硫代氨基甲酸酯配合物为起始原料,对HgS纳米颗粒(NPs)进行形状控制的合成。前体配合物双(4-苯甲酰基哌嗪-1-碳二硫酸酯-κ2S,Sʹ)汞(II),双(4-苄基哌嗪-1-碳二硫酸酯-κ2S,Sʹ)汞(II),双(4-羟乙基哌嗪-1) -碳二硫代酸酯-κ2S,Sʹ)汞(II),双(4-苄基哌啶-1-碳二硫代酯-κ2S,Sʹ)汞(II)和丙烷-1,3-二基-双(哌啶碳氨基二硫代硫酸盐)汞(II),通过化学分析(CHNS)和FT-IR,1H和13C NMR光谱对分别称为[Hg(L1)2]至[Hg(L5)2]的化合物进行表征。还对两个配合物[Hg(L1)2]和[Hg(L2)2]进行了单晶XRD分析,以识别其分子和超分子特征。前体复合物向HgS NP的转化是通过在环境压力和低温下在乙二胺(en)中进行热解而没有任何外部添加的有毒表面活性剂来实现的。通
