Abstract


Paper with a 9 - carboxy acridine , 1,2,4 - triazole and 3,4 ( 3,5 ) - pyridine dicarboxylic acid as the research object, solution method and solvothermal synthesis of a series of self-assembled novel structure coordination polymers , and explores in depth the relationship between structure and properties . This paper is divided into five chapters . The first chapter introduces the background of this study , and stressed the role of a weak group in the self- assembly of polymers and describes the role of interludes , holes polymer research progress and the current status quo . The second chapter describes the 9 - and Ag acridine carboxylic at room temperature through the weak interaction ( π-π stacking and hydrogen bonding ) to form multi-dimensional structure, and without changing the 9 - and Ag ratio of acridine carboxylic conditions introduction of a second ligand of the observed structural changes . Final study of the relationship between structure and fluorescence . The third chapter of the 1,2,4 - triazole and Cu2, Cu, Ag at high temperature ( greater than 140 ) self-assemble into three novel coordination polymer structure through weak interactions ( pro- metal effect ) synthesized eight fold interpenetrating structures. Successfully designed and synthesized from 2D to 3D , from five to eight heavy heavy interludes interspersed , from no holes to large holes ( 15.967 ? ) Coordination polymers , and continue to study the structure and nature of the relationship between the fluorescence . The fourth chapter of the 3,4 - pyridine dicarboxylic acid and 4,4 - bipyridyl mixed to form two -dimensional structure of 4,4 - bipyridine in a different metal ions (Cu2, Co2) , respectively, under the influence serves as a connection member (Linker) and ligand point effect. And continue to explore the 3,5 - pyridine dicarboxylic acid and a second ligand 1,2,4 -triazole as mixed , with Co2 successfully synthesized two quad-core small cluster . Single change in solvent does not affect the overall structure of small clusters , and through some simple topological analysis of network topology . Chapter V of the entire thesis work are summarized and discussed.
