titleOfInvention | New polymeric fluorescent substance and polymer light-emitting device using the same |
abstract | The present invention provides a polymeric fluorescent substance showing fluorescence in the solid state, having a polystyrene reduced number-average molecular weight of 10 3 to 10 8 , which comprises one or more repeating units of formula (1):n nwherein R 1 , R 2 , R 3 and R 4 each independently represent a hydrogen atom or a substituent, and at least one of R 1 , R 2 , R 3 and R 4 is a group selected from alkoxy groups, aryl groups substituted with an alkoxy group, aryloxy groups and arylalkoxy groups, nand one or more repeating units of formula (2): n n -Ar 1 - (2) n nwherein Ar 1 represents a different group from that of formula (1) and is a group selected from repeating units of formula (6):n nwherein, R 8 , R 9 and R 10 each independently represent a group selected from alkyl groups having 1 to 20 carbon atoms, alkoxy groups having 1 to 20 carbon atoms, alkylthio groups having 1 to 20 carbon atoms, alkylsilyl groups having 1 to 60 carbon atoms, alkylamino groups having 1 to 40 carbon atoms, aryl groups having 6 to 60 carbon atoms, aryloxy groups having 6 to 60 carbon atoms, arylsilyl groups having 6 to 60 carbon atoms, arylamino groups having 6 to 60 carbon atoms, arylalkyl groups having 7 to 60 carbon atoms, arylalkoxy groups having 7 to 60 carbon atoms, arylalkylsilyl groups having 7 to 60 carbon atoms, arylalkylamino groups having 7 to 60 carbon atoms, arylalkenyl groups having 8 to 60 carbon atoms, arylalkynyl groups having 8 to 60 carbon atoms, monovalent heterocyclic compound groups having 4 to 60 carbon atoms and cyano group; i and j each independently represent an integer of 0 to 4, k represents an integer of 0 to 5, h represents an integer of 1 to 2; when i is 2 or more, a plurality of R 8 s may be the same or different; when j is 2 or more, a plurality of R 9 s may be the same or different; when k is 2 or more, a plurality of R 10 s may be the same or different; two or more of R 8 to R 10 may be connected to form a ring; and further, when one or more of R 8 to R 10 is a group containing an alkyl chain, one or more of a methyl group, methylene group and methine group constituting the alkyl chain may be substituted with a group containing a hetero atom, nwherein the total amount of repeating units of formula (1) is 10 mol% or more and 90 mol% or less based on the total amount of repeating units of formulae (1) and (2) and the total amount of repeating units of formulae (1) and (2) is 60 mol% or more, which exhibits strong fluorescence and/or excellent charge transporting property, nand a high performance polymer LED which can be driven at low voltage and high efficiency. |
