Abstract

Abstract Organic redox molecules have attracted considerable attention because of their abundant availability and excellent design flexibility. For practical applications, these molecules must be anchored onto scaffolds such as polymers to prevent crystallization and elution into the electrolyte. In this study, we explore the use of polyhedral oligomeric silsesquioxane (POSS) derivatives as scaffolds for anthraquinone (AQ) and hydroquinone. We investigated the cage structure of POSS and the number of redox units incorporated. Notably, a corner‐opened POSS (CO‐POSS) variant with three AQ units exhibited reversible redox behavior under neutral, acidic, and basic conditions. Furthermore, we examined the air‐battery performance of AQ‐modified CO‐POSS as an anode‐active material.

44. Initially we used allyl alcohol instead of ethylene glycol monoallyl ether but the complex mixture was obtained probably due to theO-silylation. Therefore we selected ethylene glycol monoallyl ether. The difference in molecular weight between allyl alcohol (58.1) and ethylene glycol monoallyl ether (102.1) is 44.0. Given that the theoretical capacity is inversely proportional to the molecular weight and that there are three linkers per molecule the impact is 6.7 % for3 c(molecular weight: 1974.1). This means that the impact of long alkyl chain on theoretical capacity is limited in the present case.
