A rare (3,4,5)-connected metal–organic framework featuring an unprecedented 1D + 2D → 3D self-interpenetrated array and an O-atom lined pore surface: structure and controlled drug release

Abstract

A rare (3,4,5)-connected self-interpenetrated metal–organic framework with an O-atom lined pore surface has been constructed from Zn(II) and H₄L (H₄L = 5,5′-(1,3,6,8-tetraoxobenzo[lmn][3,8]phenanthroline-2,7(1H,3H,6H,8H)diyl)-diisophthalic acid), which features an unprecedented 1D + 2D → 3D self-interpenetrated array and shows good controlled drug release properties.
