## Description

- description: Octaphenyl POSS (OPOSS), which has phenyl groups as organic functional
    groups, is a promising ionic conductor nanomaterial. Sulfonation can be performed
    on the eight phenyl groups. SPOSS has been studied as an ionic conductor and a
    conductivity-enhancing additive. Most published studies have focused on qualita-tive
    evaluations of SPOSS, with few quantita-tive evaluations. To my knowledge, no
    quantitative analysis of SPOSS with eight sulfonate groups on eight phenyl groups
    has been performed. Conventional sulfonation methods (ClSO3H, oleum acid, H2SO4)
    can introduce four sulfonic acid groups to the octaphenyl groups. However, the
    POSS structure is prone to hydrolysis during the sulfonation process and the subsequent
    acid removal process, making the synthesis of SPOSS with all POSS structures challenging.
    In this study, I introduced two to four sulfonic acid groups into OPOSS using
    ClSO3H and H2SO4. It was found that the introduction of sulfonic acid groups not
    only depends on the type of sulfuric acid, temperature, and time, but also on
    the process of removing the remaining acid so that POSS does not break down.
