title: 3D alkyne-azide cycloaddition: spatiotemporally controlled by combination of aryl azide photochemistry and two-photon grafting.
abstract: A novel fluoroaryl azide with an alkyne tail was synthesized and precisely immobilized within a PEG-based matrix via two-photon induced decomposition and nitrene insertion. Well defined 3D positioning of the terminal alkyne allows site-specific micropatterning. The subsequent 3D alkyne-azide cycloaddition was realized using dye-functionalized molecules containing "clickable" azide moieties.
