The first preparation of a styryl-functionalized aryl pentafulvene 4 was carried out. In the crystal structure of 4, the packing of fulvene molecules results in the shortest intermolecular contacts between aligned vinyl groups. Thermal reactivity studies of 4 (DSC and TGA, under N2) revealed a small difference between the melting point (120 °C) and the Tonset for cross-linking (125 °C), and provided
进行苯乙烯基官能化的芳基五氟戊烯4的第一制备。在4的晶体结构中,富烯分子的堆积导致排列的乙烯基之间的分子间接触最短。的热反应性研究4(DSC和TGA,N下2)揭示的熔点(120℃)和差小Ť发病用于交联(125℃),并提供了有力的证据用于生产的网络材料(net4)由于连接的苯乙烯基具有反应性。N 2下net4的热解 粉末X射线分析和TGA分析表明,该产品以低收率得到了玻璃状碳产品(碳收率(TGA)为38%(900°C))。
