Kurzbeschreibung (Abstract)
For high throughput applications, e.g., in the context of sensing especially when being combined with machine learning, large sample numbers in acceptable production time are required. This needs automated synthesis and material functionalization concepts ideally combined with high precision. To automate sensing relevant mesopore polymer functionalization while being highly precise in polymer placement, polymer amount control, and polymer sequence design, a process for polymer writing in mesoporous silica films with pore diameter in the range of 13 nm is developed. Mesoporous films are functionalized with different polymers in adjustable polymer amount including block‐copolymer functionalization in an automated process using a visible‐light induced, controlled photo electron/energy transfer‐reversible addition‐fragmentation chain‐transfer (PET‐RAFT) polymerization. While transferring this PET‐RAFT to a commercially available microscope, direct, automated laser writing of three different polymers, as well as polymer re‐initiation is demonstrated. Using a laser diameter of ≈72 µm, significantly smaller polymer spots of ≈7 µm in diameter are realized. Micrometerscale resolved polymer images including block‐copolymers are written into mesoporous layers covering millimeter scale areas requiring a writing time in the range of one second per polymer spot.
