| 中文摘要: |
| 本文利用配位驱动自组装方法在溶液中合成了一类新型的四硫富瓦烯-吡啶-铜(I)配合物[CuI(L1)4](ClO4)2,(L1=4-ethylenedithiotetrathiafulvalenylpyridine),并对其微晶和单晶的结构进行表征。通过元素分析、红外光谱和X射线衍射分析确定了该配合物晶体纯度与晶体结构。发现该配合物可通过S…S非共价相互作用组装成三维超分子网络,并且其超分子链[Cu(L1)4]∞沿c轴(8.05 ′ 7.67 ?)可形成一维微孔骨架。由于该配合物沿c轴方向可构建一维均匀的TTF+1/4阵列,我们发现该配合物中具有较好的半导体特性,其电导srt与活化能Ea分别为9.1 ′ 10-2 S cm-1和50 meV。 |
| 英文摘要: |
| A novel Cu(I) coordination complex [CuI(L1)4](ClO4)2, (L1=4-ethylenedithiotetrathiafulvalenylpyridine) was synthesized by coordination-driven self-assemble method through a solution process and characterized with micro and bulk crystals forms. The purity of the micro crystals was confirmed by the elemental analysis and XRD results. In the bulk crystal form, the complex [CuI(L1)4](ClO4)2 is mononuclear and further assembles into a 3D supramolecular network through S…S noncovalent interactions. And more, the supramolecular chain [CuI(L1)4]∞forms an one-dimensional microporous framework along c axis (8.05 ′ 7.67 ?). Due to the construction of a one-dimensional uniform array of the TTF+1/4 along the c axis, a semiconducting behavior is observed in complex [CuI(L1)4](ClO4)2 with srt = 9.1 ′ 10-2 S cm-1 and an activation energy of Ea = 50 meV |
