In-solution patterning of standing up porphyrin based nanostructures within hydrogen bonded porous networks – a structural effect of a host matrix on guest entities

Abstract

Through an all-solution process, we elaborate a host–guest system based on the self-assembly of a porphyrin derivative entrapped in a PTCDI–melamine porous network on Au(111). In contrast to the unpatterned molecular assembly, complementary STM and surface IR spectroscopy show that the host template modifies the packing and the tilt angle of porphyrin nanodomains.
