Dendrimers based on ruthenium (UU) and osmium (II) Polypyridine complexes and the approach of using complexes as ligands and complexes as metals

摘要

The use of the "complexes as ligands and complexes as metals" synthetic strategy for the preparation of lumines- cent and redox-active Ru(ii) and Os(II) dendrimers, the dominant synthetic approach for this novel class of com- pounds, is reviewed. A few comments on the photophysical and redox properties of the metal dendrimers are provided and an overview of alternative synthetic approaches is also presented.
