Chiral framework with 20-ring channels exhibiting metal-activator-free photoluminescence.

The use of biomass-derived sucrose has unprecedentedly induced the first chiral zinc phosphite structure with 20R channels along with a series of acentric frameworks, unveiling a facile synthesis of chiral nanoporous frameworks. The 20R-channel structures are metal-activator free but display blue-to-white photoluminescence under long UV excitation.
