Supramolecular Palladium Complexes Based on Guanidinium Pillar[5]arene for Cancer Therapy

A supramolecular palladium complex (G-Pd) is formed through the self-assembly of the Pd-complex obtained by the coordination of guanidinium pillar[5]arene with Pd 2+ , which was used to encapsulate DOX (G-Pd@DOX) for cancer therapy.
