time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) and spatially‐resolved X‐ray photoelectron spectroscopy (XPS) mapping, supporting the preserved chemical composition of the surface‐bound metallopolymers. The established photochemical technology platform for arbitrary spatially‐resolved metallopolymer surface designs enables the patterning of multiple metallopolymers onto solid substrates. This allows for

biointerfaces. Precision photolithography of a modified β‐CD was established on a light sensitive tetrazole surface immobilized on a bioinspired polydopamine (PDA) anchor layer via various shadow masks, as well as via direct laser writing (DLW), in order to craft any desired printboard design. Interfacial molecular recognition provided by light generated cavitate domains was demonstrated via spatially resolved

A facile, fast and ambient-temperature avenue towards highly fluorescent polymers is introduced via polymerizing non-fluorescent photoreactive monomers based on light-induced NITEC chemistry, providing a platform technology for fluorescent polymers. The resulting polypyrazolines were analyzed in depth.
fluorescence‐based methodology enabling the quantification of ligation points in photochemically prepared polymer networks. Well‐defined α,ω‐tetrazole‐capped polymer strands prepared via RAFT polymerization are crosslinked under UV irradiation by a trimaleimide via nitrileimine mediated tetrazole–ene cycloaddition. Thus, for each linkage point a fluorescent pyrazoline ring is formed, resulting in fluorescent
