Supramolecular Nanostructures of Phthalocyanines and Porphyrins at Surfaces Based on the 'Bottom-Up Assembly'

摘要

The "bottom-up" strategy is an attractive and promising approach for the construction of nanoarchitectures. Supramolecular assemblies based on noncova-lent interactions have been explored in an attempt to control the surface properties. In this chapter, we focus on advances made in the past 5 years in the field of scanning tunneling microscopy (STM) on supramolecularly nanostructured phthalo-cyanines and porphyrins on single-crystal surfaces. The design of supramolecular nanoarchitectures consisting of phthalocyanines and porphyrins, supramolecular traps of C_(60) and coannulene, direct metallation on phthalocyanines and porphyrins adlayers, direct synthesis of porphyrin oligomers at surfaces, axial coordination of phthalocyanines and porphyrins, and nanoapplications induced by tip manipulation at surfaces were clearly visualized by STM.
