Abstract

Summary: A soluble, regular, ethoxy‐capped, ladder poly(silsesquioxane) (EtO‐LPOAS) has been successfully synthesized by means of the concerted H‐bonding template of silanol and amido groups, through a new template monomer M: tetraethoxy disiloxane bisamide compound. EtO‐LPOAS was characterized by X‐ray diffraction (XRD), ^29^Si NMR spectroscopy and DSC measurements. The results confirm the presence of the regular, ladder structure of EtO‐LPOAS. This synthetic method has opened a new route to other new kinds of functional ladder poly(silsesquioxane)s.

Schematic overview of the mechanism for synthesis of EtO‐LPOAS.
