Redox-Active, Organometallic Surface-Relief Gratings from Azobenzene-Containing Polyferrocenylsilane Block Copolymers

Organometallic Gratings: The ionic self‐assembly of metal‐containing block‐copolymer polyelectrolytes and azobenzene chromophores is exploited for the efficient production of stable photo‐induced surface‐relief gratings. We show that feature sizes can be tuned using simple redox chemistry, and that the chromophores can be removed during plasma treatment to yield ceramic‐based optical materials.
