General surface functionalization procedure. The polymeric surfaces were spincoated with a solution of compound 15 and irradiated with UV-light (254 nm) for 5 min. The NHS-activated ester surfaces were linked through an amidation process with amine 14 or 16 to produce the alkene/alkyne functionalized surfaces. The alkene/alkyne surfaces were then differentiated with thiol-functionalized molecules (4, 8, 17, 18 or 19) through radical photo-click chemistry.
