Synthesis of a new cross-linkable perfluorocyclobutane-based hole-transport material.

[reaction: see text] A new curable arylamine containing a perfluorocyclobutane (PFCB) structure without an acidic group was synthesized. The material was thermally cured on ITO after spin-coating. The polymer showed excellent solvent resistance, high thermal stability, high transparency, and good surface smoothness.
