Patent number: 6949621Abstract: 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 arylenebisboronic acid and polycondensation, or to polycondensation with an olefin.Type: GrantFiled: February 27, 2002Date of Patent: September 27, 2005Assignees: Japan Science and Technology Corporation, National Institute of Advanced Industrial Science and TechnologyInventors: Yoshikazu Makioka, Masato Tanaka, Teruyuki Hayashi
