    • Compositions and methods are provided in which nanoporous polymeric materials are produced via stable, polymeric template strands having reactive groups that can be used for forming crosslinking functionalities and/or adding thermolabile groups, wherein at least some of the thermolabile groups are thermolyzed to produce voids. The template strands preferably comprise aromatic systems and vicinal keto groups, such as a polybenzil formed from fluorene bisphenol or 3,3'-dihydroxytolane with 4,4'-difluorobenzil. At least some of the reactive groups preferably react using an addition-elimination reaction. Especially preferred thermolabile groups comprise poly(propylene oxide), and especially preferred crosslinkers comprise ethynyl-moiety and tetracyclone moieties.

    • In a method of producing a low dielectric constant polymer, a thermosetting monomer is provided, wherein the thermosetting monomer has a cage compound or aryl core structure, and a plurality of arms that are covalently bound to the cage compound or core structure. In a subsequent step, the thermosetting monomer is incorporated into a polymer to form the low dielectric constant polymer, wherein the incorporation into the polymer comprises a chemical reaction of a triple bond that is located in at least one of the arms. Contemplated cage compounds and core structures include adamantane, diamantane, silicon, a phenyl group and a sexiphenylene group, while preferred arms include an arylene, a branched arylene, and an arylene ether. The thermosetting monomers may advantageously be employed to produce low-k dielectric material in electronic devices, and the dielectric constant of the polymer can be controlled by varying the overall length of the arms.
    • 在制造低介电常数聚合物的方法中,提供了一种热固性单体,其中该热固性单体具有笼形化合物或芳基核心结构,以及共价结合笼形化合物或核心结构的多个臂。 在随后的步骤中,将热固性单体引入聚合物中以形成低介电常数聚合物,其中掺入聚合物中包含位于至少一个臂中的三键的化学反应。 考虑的笼状化合物和核心结构包括金刚烷,二金刚烷,硅,苯基和亚噻吩基,而优选的臂包括亚芳基,支链亚芳基和亚芳基醚。 热固性单体可以有利地用于在电子器件中产生低k介电材料,并且聚合物的介电常数可以通过改变臂的整个长度来控制。
