Title:
POLYMER CONTAINING 9-OXO-9-PHOSPHAFLUORENE-2,7-DIYL SKELETON IN BACKBONE AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2002/072661
Kind Code:
A1
Abstract:
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.
