4-(Diphenylamino)phenylboronic acid (CAS 201802-67-7)

Application and positioning

A triphenylamine carrying a boronic acid on one ring, so the hole-transporting unit can be attached to any aryl halide in one step. It is used for hole-transport layers, dye-sensitised solar cell sensitisers and donor-acceptor fluorophores. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.
