  摘要：

  The reaction of dilithiobutadiyne (or the corresponding di-Grignard reagent) with various dichlorosilanes and dibromogermanes in THF at room temperature afforded poly[(silylene)diacetylenes] and poly[(germylene)diacetylenes], respectively, in high yields. The polymers have a regular alternating arrangement of diyne and silylene or germylene units. When they are doped with FeCl3, these polymers show conductivity values in the range 10(-5)-10(-3) S.cm-1. The values depend greatly on the electronic character of the substituents bonded to silicon or germanium.

  Polymer derived ceramics have received lots of attention throughout the last few decades. Unfortunately, only a few precursor systems have been developed, focusing on silicon based polymers and ceramics, respectively. Herein, the synthesis of novel hafnium containing organometallic polymers by two different approaches is reported. Dialkenyl substituted hafnocene monomers were synthesized and subsequently polymerized via a free radical mechanism. Salt metathesis reactions of hafnocene dichloride with bifunctional linkers led to the formation of polymeric materials. NMR spectroscopic methods – in solution as well as in the solid state – were used to characterize the organometallic polymers. Ceramics were finally obtained after cross-linking and thermal treatment under argon (Tmax = 1800 °C). SEM investigations, elemental analyses, Raman spectroscopy and XRD investigations identified the pyrolyzed products as partially crystalline HfC/C mixed phases.

  过去几十年来，聚合物衍生陶瓷受到了广泛关注。遗憾的是，目前仅开发出几种前驱体系统，分别侧重于硅基聚合物和陶瓷。本文报告了通过两种不同方法合成新型含铪有机金属聚合物的情况。合成了二苯乙烯取代的铪单体，随后通过自由基机制进行聚合。二氯化铪与双官能团连接体的盐偏合成反应导致了聚合物材料的形成。利用核磁共振光谱方法（溶液和固态）对有机金属聚合物进行了表征。经过交联和氩气热处理（Tmax = 1800 °C）后，最终获得了陶瓷。通过 SEM 研究、元素分析、拉曼光谱和 XRD 研究，确定热解产物为部分结晶的 HfC/C 混合相。

• Polyyn-diyls Capped by Diruthenium Termini:  A New Family of Carbon-Rich Organometallic Compounds and Distance-Dependent Electronic Coupling Therein

  Polyyn-diyls capped by Ru-2(ap)(4) termini (ap = 2-anilinopyridinate), that is, [Ru-2(ap)(4)](mu-C,C'-C-2m)[Ru-2(ap)(4)] (compounds 1-5 with m = 1-4 and 6), were synthesized through either a metathesis reaction between Ru-2(ap)(4)Cl and LiC2mLi or a Glaser homocoupling reaction of Ru-2(ap)(4)(CmH) under Eglinton/Hay conditions. X-ray diffraction studies of compounds 2 and 4 revealed both the linear rigid rod topology of these compounds and the fine structural details about the Ru-2 cores and polyyn-diyl chains. Cyclic and differential pulse voltammetric (CV and DPV) measurements and spectroelectrochemical studies show that reduced and oxidized forms of 1, 2, 4, and 5 are donor-acceptor systems in which the Ru-2 termini are coupled to varying degrees depending upon the length of the polyyn-diyl bridge.
