Tailoring Surface-Confined Nanopores with Photoresponsive Groups

摘要

Recently, the construction of two-dimensional (2D) porous patterns on solid surfaces using molecular self-assembly has become a subject of interest because of potential applications in nanoscience and nanotechnology, for nanoreactors and catalysts that may function cooperatively with substrate surfaces and for molecular wires and 2D polymers generated by surface-controlled reactions. Surface-confined pores within the 2D porous molecular networks can be used as a host space to immobilize guest molecules at the surface. These molecular networks are typically observed by means of scanning tunneling microscopy (STM) under ultrahigh vacuum (UHV) conditions or at the liquid-solid interface.
