<p><P>PROBLEM TO BE SOLVED: To provide a luminescent polymer comprising a triarylene repeat unit which comprises a triarylene which is substituted or unsubstituted and an arylene repeat unit: -[-Ar-]-: that is different from the triarylene repeat unit. <P>SOLUTION: This luminescent polymer comprising the triarylene repeat unit in which one of arylene rings constituting the triarylene repeat unit is a heterogeneous condensed ring containing two nitrogen atoms and the others form each independently a ring containing O, S, CR<SB>2</SB>, SiR<SB>2</SB>or NR (each R is independently alkyl, aryl or H). <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
