Supramolecular architecture-directed synthesis of a reactive and purely inorganic ladder polyhydrosilsesquioxane

摘要

A reactive and purely inorganic high Mw perfect ladder polyhydrosilsesquioxane (H-LPSQ) was first prepared under the direction of two imperative supramolecular architectures: ladder superstructure (H-LS) and donor-acceptor complex (DAC).rnLadder polymers are of special importance as advanced materials due to their superior thermo-resistance and mechanical strength.1 Recently, many studies have focused on high molecular weight (Mw) ladder organo-grafted polysilsesquioxanes (R-LPSQs) for their unique hybrid double chain structures.
