In addition to the cationic twin polymerization on polar surfaces such as SiO2 or cellulose the second part of the project will focus on the base catalyzed twin polymerization of 2,2'-Spirobis[4H-1,3,2]-benzodioxasilin (1) and derivatives on carbon surfaces of graphite, graphene, carbon nanotubes, and amorphous carbon as well as metal particles. The twin polymerization of 1 catalyzed with bases like diazabicyclo[2.2.2]octane (DABCO) or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) is conducted to coat graphit particles as well as to obtain new intercalation compounds for the integration of different carbon morphologies into carbon/carbon nanocomposites. An important goal is the synthesis of graphene/microporous glass-like carbon hybrid materials as electric conducting composites which can be applied as electrode materials in energy storage applications. In this context it is as well subject of investigation if heteroatom doped carbon is accessible via base catalyzed twin polymerization. For this aspect new twin monomers have to be synthesized and investigated.The prefunctionalization of metal surfaces like copper with secondary amines (e.g. pyrrolidine) should be used to extend the surface twin polymerization on metal surfaces and integrate them into carbon matrices.

除了在极性表面如SiO2或纤维素上的阳离子双聚合之外，该项目的第二部分将集中在2，2 '-螺双[4 H-1，3，2]-苯并二氧杂环己二烯（1）和衍生物在石墨、石墨烯、碳纳米管和无定形碳以及金属颗粒的碳表面上的碱催化双聚合。以二氮杂双环[2.2.2]辛烷（DABCO）或1，8-二氮杂双环[5.4.0]十一碳-7-烯（DBU）等碱为催化剂，进行1的双聚合，包覆石墨颗粒，并获得新型插层化合物，用于将不同形貌的碳整合到碳/碳纳米复合材料中。一个重要的目标是合成作为导电复合材料的石墨烯/微孔玻璃状碳杂化材料，其可用作储能应用中的电极材料。在这种情况下，如果杂原子掺杂的碳可通过碱催化的双聚合来获得，则也是研究的主题。因此，必须合成和研究新的孪晶单体，用仲胺（如吡咯烷）对铜等金属表面进行预官能化，以扩展金属表面的孪晶聚合，并将其整合到碳基体中。
