CA 2425039

A polymer containing in the backbone a 9-oxo-9-phosphafluorene-2,7-diyl skeleton or a combination of the skeleton with a vinylene skeleton or arylene skeleton. The polymer is utilizable as, e.g., a component of a luminescent element or electrochromic element. The polymer is obtained by subjecting a 2,7- dihalo-9-oxo-9-phosphafluorene to polycondensation with dehalogenation, or to reaction with allylene bisboronic acid and polycondensation, or to polycondensation with an olefin.

L'invention concerne un polymère contenant dans la chaîne principale un squelette 9-oxo-9-phosphafluorène-2,7-diyle ou une combinaison de ce squelette avec un squelette vinylène ou un squelette arylène. Ce polymère peut être utilisé par exemple comme composant d'un élément luminescent ou électrochimique. On peut obtenir ce polymère en soumettant un 2,7-dihalo-9-oxo-9-phosphafluorène à une polycondensation avec déshalogénation ou à une réaction avec de l'acide bisboronique d'allylène et à une polycondensation, ou à une polycondensation avec une oléfine.
