| 摘 要： | 以原位N-烷基化合成的苯并咪唑衍生物R2-bzim(R=H-,CH3-,C6H5CH2-;bzim=苯并咪唑)为模板,合成了3个含一维PbI3-盐的无机-有机杂化材料.X射线单晶衍射结果表明,随着模板剂尺寸的增大一维无机链由双链结构转变为单链结构.相对于体相PbI2,这些化合物有0.38～0.46eV的带隙蓝移,体现出比较强的量子限域效应.光致发光研究表明,通过模板剂的调控,3个化合物分别表现出绿、橙、黄光发射.

| Abstract: | A series of benzimidazole derivatives R2-bzim(R=H-,CH3-,C6H5CH2-;bzim=benzimidazole) templated 1-D PbI3 -based inorganic-organic hybrids have been synthesized by an in situ N-alkylation solvothermal method.The 1D PbI3 -chains in these compounds change from a double-chain to a single-chain structure with the increase of the size of templates.Optical diffuse reflection experiments show that all compounds exhibit a blue shift in their absorption edge(0.38,0.43,0.46 eV,respectively) ,due to the quantum confinem... |
