| Summary: | 碩士 === 輔仁大學 === 化學系 === 99 === In recent years, many kinds of MOFs are reported, in order to develop a self–assembly synthetic method for the preparation of metal–organic coordination polymers using dicarboxylic anhydride and chiral ligand with transsition metal ions.
A). In-situ hydrolysis of dicarboxylic anhydride towards polycarboxylate groups, is used as controlled process in the self-assembly synthesis of target compounds.
B). Due to its chiral nature, tartaric acid is a useful raw material for the synthesis of chiral compounds. Two type of 2D metal–organic frameworks display two crystal system and space group between Cu and Zn ions. {Cu2(C4H4O6)2(H2O)2．4H2O} 4 and {M2(C4H406)2(H20)2．3H2O} [ M= 5a (Zn)，5b (Co)，5c (Ni) ] Physical Properties for single crystal X–ray, powder X–ray diffraction, ATR–IR, thermal gravimetric analysis, differential thermal analysis, etc.
For compound 4, the Cu2+ ions that bridged by a syn-anti carboxylate ligand in a chain fashion are coupled ferromagnetically, the weak interchain interaction indicating the ferromagnetic coupling.
