Easy, quantitative, and one-pot introduction of eight β -lactoside-modules onto a porphyrin-core was achieved through Cu+ -catalyzed chemoselective coupling (click chemistry) between a porphyrin carrying eight alkyne-terminals and β -lactosyl azides. The obtained porphyrin-based glycocluster shows not only good water-solubility but also strong/specific lectin-affinity.
