| titleOfInvention | Polymer fluorescent substance and organic electroluminescence device |
| abstract | A polymeric fluorescent substance having visiblenfluorescence in a solid state and a polystyrene-reducednnumber-average molecular weight of 10 3 to 10 7 , which containsnat least one repeating unit represented by the followingnformula (1),n -Ar 1 -CR 1 =CR 2 - nwherein the sum of the repeating unit is from 10 to 100 mol%nof the total number of the repeating units, Ar 1 representsnan arylene group having 4 to 20 carbon atoms taking partnin conjugated bonds and containing at least one substituentnrepresented by the following formula (2) as a nuclearnsubstituent, or a heterocyclic compound group, having 4 ton20 carbon atoms taking part in conjugated bonds, andncontaining at least one substituent represented by thenfollowing formula (2) as a nuclear substituent; and R 1 andnR 2 independently represent a group selected from the groupnconsisting of hydrogen, an alkyl group having 1 to 20 carbonnatoms, an aryl group having 6 to 20 carbon atoms, anheterocyclic compound group having 4 to 20 carbon atoms andna cyano group,n -(X) m -(CH 2 ) n -Ar 2 nwherein Ar 2 represents a group selected from the groupnconsisting of an aryl group and having 4 to 20 carbon atomsntaking part in conjugated bonds, a heterocyclic compound ngroup, having 4 to 20 carbon atoms taking part in thenconjugated bonds, and an aliphatic cyclic hydrocarbonncompound group having 6 to 20 carbon atoms constituting thenring; X represents O or S; m represents 0 or 1; and nnrepresents an integer of 2 to 10. n The polymeric fluorescent substance is excellent asna material for organic EL devices because of strongnfluorescence and good thermal stability. Furthermore, thendevicean organic EL device using the polymeric fluorescentnsubstance can be preferably used as a flat light source fornback light or a device such as a flat panel display and thenlike because it is easily produced and exhibits excellentnlight emitting characteristics and a heat resistance. |
