The “bottom-up” strategy is an attractive and promising approach for the construction of nanoarchitectures. Supramolecular assemblies based on noncovalent 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 phthalocyanines...
The approach based on the copper(I)-templated synthesis of porphyrin catenanes and rotaxanes developed by the authors' group is here reviewed. Zn(II) porphyrins and gold(III) porphyrins were chosen as electron donors and electron acceptors, respectively, to constitute the electro- and photoactive parts of the present systems. The processes—energy and electron transfer reactions—occurring in the interlocked...
After a brief introduction to the theory of time-dependent density functional theory (TDDFT), an overview is given of the recent literature on calculations of the electronic absorption spectra of transition-metal complexes. Various types of complexes are treated – organometallic complexes with carbonyl and cyclopentadienyl ligands, oxo and halide complexes (Werner complexes), metal α-diimine complexes...
