A chiral diamondoid 3D lanthanum metal-organic framework displaying blue-greenish long lifetime photoluminescence emission

The compound [La(pmtz)(TzC)(H2O)(3)](H2O) (pmtz = 5-(pyrimidyl)-tetrazolato, TzC = 5-carboxylato-tetrazolato) has been prepared under hydrothermal conditions and exhibits a 3D diamondoid network. This three-dimensional metal-organic framework has channels with hosted water molecules inside and shows an intense blue-greenish long lifetime photoluminescence emission at room temperature in the solid state with two lifetime decay values of 0.26 and 27 ms.
