syntheses. The formation of 1D coordination polymers was proven by crystal structure determinations of two of the polymeric materials. The geometries and electronic structures of all polymers were analysed further by CASSCF/CASPT2 and DFT calculations based on monomeric model compounds. Finally, first attempts regarding deposition of the 1D chain, the sawhorse fragment and/or the ligands on a highly ordered
报道了五种一维配位聚合物的合成,这些聚合物包含通过各种桥联的N,N-供体配体连接的锯齿型单元[Ru 2(µ-OAc)2(CO)4 ]。各种π共轭连接子,例如反式[1,2-双(N-甲基)咪唑-2-基]乙烯(反式-bie),吡嗪(pyz),4,4'-联吡啶(4,4'-bipy)和1,2-双(4-吡啶基)乙烯(bpe)以及脂肪族连接基1,4-二氮杂双环[ 2.2.2]辛烷(DABCO)用于合成。一维配位聚合物的形成已通过两种聚合物材料的晶体结构确定得到了证明。通过CASSCF / CASPT2和基于单体模型化合物的DFT计算,进一步分析了所有聚合物的几何结构和电子结构。最后,还报道了有关通过STM测量分析一维链,锯齿状片段和/或配体在高度有序的热解石墨表面上沉积的首次尝试。
