Abstract Patterned alignment of functional organic molecules on surfaces is increasingly investigated due to numerous promising applications in micro- and nanotechnology. Chemical surface patterning attracts particular importance in such fields of biotechnology in which a controlled surface immobilization of biomolecules like enzymes or proteins is desired, e.g., for the development of biosensors. For various applications, the controlled, site-specific positioning of molecules or functional nanoparticles on surfaces is indeed a critical prerequisite. In particular, site-selective provision of functional groups is required for the reliable, site-specific attachment of functional molecules and, hence, the fabrication of regularly spaced functional arrays. Control over spatial distribution of chemical surface functionalities constitutes a major demand in diverse material applications, e.g., for the fabrication of DNA chips. Therefore, in this Communication we introduce, synthesized by a double-click approach, photopatternable block copolymers films allowing to provide site-specific amino functions and covalent attachment specifically on gold surfaces.
