A prototype photothermal procedure: Alkylsiloxane monolayers on surface‐oxidized silicon substrates are processed in gaseous bromine using a focused Ar + ‐laser operated at λ =514 nm. Monolayer bromination remains confined to a micrometer‐sized reaction zone, where laser irradiation results in a local temperature rise (see figure).
