Luminescent cluster-organic frameworks constructed from predesigned supertetrahedral {Ln4Zn6} secondary building units. Issue 56 (22nd June 2021) - Ge, Rui
Abstract : A new type of 3d–4f supertetrahedral cluster has been introduced for the first time as a secondary building unit to construct luminescent cluster-organic frameworks with tunable emission, demonstrating a promising strategy for new optical materials. Abstract : 3d–4f heterometallic supertetrahedral clusters with the formula of Ln4 Zn6 (μ6 -O)L4 (CH3 COO)6 (NO3 )4 (CH3 OH)4 (H2 O)2 (1-Ln, Ln = Eu, Gd, Tb, H3 L = 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.
