POLYMER, LIGHT EMITTING DEVICE, AND METHOD |
摘要 |
<p>An organic light-emitting device comprises an anode, a cathode and a light-emitting layer between the anode and the cathode. The light-emitting layer comprises a polymer having a repeat unit of formula (I): wherein A represents a repeat unit comprised in a backbone of the polymer; Sp in each occurrence independently represents a spacer group; n is 0 or 1; w is at least 1; and B in each occurrence independently represents a group of formula (II): wherein Ar1, Ar2, Ar3, Ar6 and Ar7 in each occurrence independently represent an unsubstituted or substituted aryl or heteroaryl group; X independently in each occurrence represents S or O; R independently in each occurrence represents H or a substituent; p is 0 or 1; and q is 0 or 1; f is 1, 2 or 3; g is 1, 2 or 3; and adjacent groups Ar3 or adjacent groups Ar2 may be linked by a divalent group to form a ring.</p> |
