Title LADDER-TYPE POLYSILSESQUIOXANE HAVING PHOSPHONIC ACID GROUP AND PHOSPHONATE GROUP IN SIDE CHAINS THEREOF, LADDER-TYPE POLYSILSESQUIOXANE LAMINATE, METHOD FOR PRODUCING LADDER-TYPE POLYSILSESQUIOXANE, AND METHOD FOR PRODUCING LADDER-TYPE POLYSILSESQUIOXANE LAMINATE
Abstract A ladder-type polysilsesquioxane is represented by formula 1 or formula 2. In formula 1 and formula 2, R1 represents an alkylene group having 1 to 6 carbon atoms, and n represents a positive real number. In formula 2, X represents an alkali metal cation, an alkali earth metal cation, an ammonium cation or an imidazolium cation.
Outline of related art and contending technology BACKGROUND ART
Silsesquioxane is, with respect to the silicon atom (Si) 1 and two organic substituents (R) average 1.5 oxygen atoms (O) bonded (RSiO1.5)n compounds having the structure of which is a general term. Silsesquioxane is heat resistance, has excellent durability, due to the presence of the organic substituents from having good compatibility with the organic material, organic - inorganic hybrid material in the optical communication field in recent years has attracted attention.
The polysilsesquioxane can be ladder-type, one-dimensional extend to a polymer main chain, showing the proton conductivity of the side chain substituent (for example a sulfo group or phosphonic acid group) is ladder-type polysilsesquioxane including, have excellent thermal stability, good proton conductivity and are expected to display. For this reason, the polysilsesquioxane can be such a ladder-type, solid polymer type fuel cell to be used as the solid electrolyte has been studied. Application to the ladder-type polysilsesquioxane with respect to the solid electrolyte, for example, patent document 1, a proton-conductive membrane 2 or the like is disclosed.
