Design of Inorganic-Organic Hybrid Materials Based on 4'-(4-methylphenyl)-2,2':6',2'-terpyridine Ligand
摘要
(一) 利用4'-(4-methylphenyl)-2,2':6',2'-terpyridine (L)與金屬離子鉺、鋱、釤、釓和銪進行水熱法自組裝合成。與硝酸銪反應得到配位化合物Eu2(L)2(C2O4) (1);與硝酸鋱反應得到配位化合物Tb2(L)2(C2O4) (2);與硝酸鉺反應得到配位化合物Er2(L)2(C2O4) (3) ;與硝酸釓反應得到配位化合物Gd2(L)2(C2O4) (4) ;與硝酸釤反應得到配位化合物Sm2(L)2(C2O4) (5)。上述5 個化合物皆為oxalato-bridged 形式，晶型為Monoclinlc 空間群為P21/c ， 另外發現其C(23)-C(23) 鍵長比普通oxalato-bridged 鍵長還長。 (二) 利用4'-(p-carboxyphenyl)-2,2':6',2'-terpyridine (p-CPTPy) 與金屬離子銅和鈷進行水熱法自組裝合成。與硝酸銅反應得到配位化合物Cu2(C22H15N4O5)2•(H2O) (6);與氯化鈷反應得到配位化合物Co(C22H14N3O2)2• H2O(7)。 本論文中共合成得七個新型金屬－有機的配位化合物，其結構經IR，以及單晶、粉末X 射線繞射解析鑑定，並利用TGA 測定其熱安定性質。

Treatment of MNO3·nH2O (M = Eu, Tb, Sm, Er, Gd) with 4'-(4-methylphenyl)-2,2':6',2'-terpyridine (L) in acetonitrile under hydrothermal conditions led to the formation of metal complexes Eu2(L)2(C2O4) (1), Tb2(L)2(C2O4) (2), Er2(L)2(C2O4) (3),Gd2(L)2(C2O4) (4) and Sm2(L)2(C2O4) (5). These products are dimetallic compounds with an oxalato-bridging group. The crystal systems in these compounds are monoclinic, with space groups of P21/c. It is noteworthy that the C-C bond length of the bridging oxalate is great than the normal bond length. Treatment of Cu(NO3)2 and CoCl2 with 4'-(p-carboxyphenyl)-2,2':6',2'-terpyridine(p-CPTPy) yielded 1-D coordination polymers of Cu2(C22H15N4O5)2•(H2O) (6) and Co(C22H14N3O2)2•H2O(7), respectively. Compounds 1-7 were characterized using elemental analysis, IR, thermal analysis and X-ray powder diffraction studies. The molecular structures of products 1-7 were further confirmed by single -crystal X-ray diffraction analysis.
