Bis-phenylethynyl polyhedral oligomeric silsesquioxane (bis-PE-POSS) compounds were synthesized and thermally cured yielding crosslinked materials. After curing at 370 °C, thermal decomposition occurs near 600 °C under nitrogen. These materials were synthesized by condensation of a new phenylethynyl-functional dichlorosilane onto tetrasilanol phenyl POSS, yielding two geometric isomers.
双苯乙炔基多面体低聚倍半硅氧烷(双-PE-POSS)化合物被合成出来,并通过热固化得到交联材料。在370℃固化后,在氮气氛围下,热分解在600℃左右发生。这些材料是通过一种新型苯乙炔基官能化二氯硅烷与四硅醇苯基POSS缩合而成,产生了两种几何异构体。
