An elegant approach to generate tailored materials and nanoparticles is the formation of molecular monolayers by chemisorption of bifunctional anchor molecules (Figure 1A) [1]. The
needs to form a stable (in most cases covalent) connection to the target surface. Various bifunctionalanchors have been reported for immobilization on different materials and nanoparticles. Basically, silane derivatives are used for glass surfaces [2][3], thiols for noble metal surfaces [4
monochromator).
