4,4'-Oxydiphthalic anhydride (ODPA) CAS 1823-59-2

A dianhydride building block with a phenyl ether moiety

An intermediate for polyimides synthesis in application of super capacitors, battery anodes, fluorescence emitters and MOFs-based memory devices

Specifications | MSDS | Literature and Reviews

4,4'-Oxydiphthalic anhydride (ODPA, CAS number 1823-59-2), end-capped with two carboxylic anhydrides, is typically used for polyimide synthesis in material science. The polyimide films from 4,4'-oxydiphthalic anhydride exhibit high thermal resistance and high specific capacitance (121 F/g). They work well as separators in supercapacitors. The polyimides are also used as anodes in Li-batteries, owing to their dissolution in the electrolyte to maintain the electrochemical performance of Li-batteries.

ODPA can be hydrolysed and chelated to metal ions (e.g., indium) forming metal organic frameworks (MOFs) for multilevel flexible optoelectronic memory devices. The memory devices have over 192 distinct levels (6-bit storage) and stable retention (10000 s).
