Luminescent cluster-organic frameworks constructed from predesigned supertetrahedral {Ln4Zn6} secondary building units

3d-4f heterometallic supertetrahedral clusters with the formula of Ln(4)Zn(6)(mu(6)-O)L-4(CH3COO)(6)(NO3)(4)(CH3OH)(4)(H2O)(2) (1-Ln, Ln = Eu, Gd, Tb, H3L = 2-(hydroxymethyl)-2-(pyridin-4-yl)-1,3-propanediol) have been successfully introduced as stable secondary building units (SBUs) to construct new cluster-organic frameworks with tunable emission, demonstrating a promising strategy for developing new optical materials.
