<p>The invention provides a composition comprising at least one dopant, and a polymer comprising at least one unit selected from Structure I. Wherein M is selected from Fe, Co, or Ni; R1, R2, R3, R4 and R5 are each independently selected from hydrogen; deuterium; halogen; substituted or unsubstituted (C1-C16) alkyl; substituted or unsubstituted (C6-C16) aryl; substituted or unsubstituted (C3-Ci6) cycloalkyl; substituted or unsubstituted 5- to 7-membered heterocycloalkyl; substituted or unsubstituted (C6-C16) aryl fused with one or more cycloalkyl; 5- to 7-membered heterocycloalkyl fused with one or more substituted or unsubstituted aromatic rings or (C3-C16) cycloalkyl fused with one or more substituted or unsubstituted aromatic rings; substituted or unsubstituted (C1-C16) silyl; cyano; nitro; or hydroxy; n is greater than or equal to 1; x is from 0 to 4; and y is from 0 to 5. Wherein the dopant is a P-type dopant. These polymers, with and without dopant, are useful in the preparation of films and electronic devices, such as organic light-emitting diodes (OLED).</p> |
