A series of porous metal–organic frameworks with hendecahedron cage: Structural variation and drug slow release properties

Abstract A series of porous MOFs with hendecahedron cage-liked cavity has been constructed from the [Cu 2 (COO) 4 ] secondary building unit, H 3 L (H 3 L = [1,1';3',1'']Terphenyl-4,5',4''-tricarboxylic acid) and pyrazine derivatives varied with different sizes; the structural evolving of the hendecahedron cage and the application in drug delivery and controlled release were presented.
