Abstract:
A luminescent device having a luminescent layer or at least two thin organic compound layers including a luminescent layer, between a pair of electrodes, wherein at least one of the layers comprises at least one polymer which is(a) a polymer having at least one partial structure represented by the following formula (I): wherein R1 and R2 are the same or different, and each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted amino group, a substituted or unsubstituted heteroaryl group, or a substituted or unsubstituted aliphatic heterocyclic group; and R1 and R2 may combine with each other to form a ring, or (b) a polymer represented by the following formula (II): wherein R3 and R4 are the same or different, and each represent a substituted or unsubstituted aryl group except for an unsubstituted phenyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group which has a condensed ring, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted amino group, a substituted or unsubstituted nitrogen-containing heteroaryl group, a substituted or unsubstituted oxygen-containing heteroaryl group, or a substituted or unsubstituted aliphatic heterocyclic group, and R3 and R4 may combine with each other to form a ring; X1 and X2 are the same or different, and each represents a hydrogen atom, a halogen atom, an aliphatic hydrocarbon group, an aromatic hydrocarbon group or an aromatic heterocyclic group, and X1 and X2 may combine with each other to form a ring; and n is an integer of at least 2.
