The photochemical structuring of a polysiloxane monolayer protected with a photocleavable group is shown by femtosecond laser pulses in the near infrared. These experiments suggest a two‐photon induced deprotection process that holds great promise for near‐field monolayer photolithography far below the diffraction limit.
