surfaces encoded with a monolayer consisting of different metalcomplexes was developed. The concept entails the light‐triggered activation of a self‐ assembled monolayer (SAM) of UV‐labile anchors, that is, phenacylsulfides, and the subsequent cycloaddition of selected diene‐functionalized metalcomplexes at defined areas on the surface.

A novel and very simple photochemical strategy that utilizes light as a facile means to provide spatio-temporal control for the direct covalent immobilization of nucleophiles is presented. The concept is based upon the efficient trapping of photogenerated thioaldehydes by amines, hydroxylamines, and thiols. Surface patterns of polymers and small molecules bearing pendant amine-, hydroxylamine- or thiol moieties were successfully generated and imaged in a time-of-flight secondary-ion mass spectrometry (ToF-SIMS) investigation.
