Kingdom for a lead crown: A crown-ether-like, open PbII framework is generated from its phtotochromic precursor by a leaching approach. The dual and bimodal emissions are successfully realized by intercalation of the different Ln3+ hydrates into the hollow PbII framework based on a guest-driven approach (see graphic).
