CROSS-LINKABLE POLYMER BASED ON DIELS-ALDER REACTION AND USE THEREOF IN ORGANIC ELECTRONIC DEVICE

摘要

Provided is a mixture which can be subjected to a Diels-Alder reaction, comprising polymer (I) and polymer (II), wherein the structures of the polymer (I) and the polymer (II) are as shown in (I),; ;wherein x1, y1, x2, y2, z1 and z2 are percentage molar contents; said x1 is 0, x2 is 0, y1 is 0, y2 is 0, z1 is ≥0, and z2 is ≥0; x1+y1+z1, and x2+y2+z2=1; Ar1, Ar2, Ar2-1, Ar3, Ar4 and Ar4-1 are each independently selected from: an aryl, or heteroaryl group containing 5-40 ring atoms; R1 and R2 are each independently a linking group; D is a conjugated diene functional group, and A is a dienophilic functional group; and n1 is greater than 0, and n2 is greater than 0. The mixture for a Diels-Alder reaction has a very good optical performance.
