Abstract
A novel Zn(II) metal-organic framework [Zn 3 (tib) 2 (L) 3 ] ( 1 ) was synthesized with mixed ligands of 1,3,5-tris(1-imidazolyl)benzene (tib) and 4-carboxycinnamate (L 2 − ), exhibiting interesting two-fold interpenetration, where triple-stranded homochiral left- ( L -) and right- ( R -) handed helical chains were constructed by linear rigid ligand L 2 − and metal ions. The complex was well characterized by single crystal and powder X-ray diffractions (PXRD), infrared spectroscopy (IR), elemental analysis (EA) and thermogravimetric analysis (TGA). As a result, the complex shows high thermal stability and strong photoluminescent emission in the solid state at room temperature. A novel Zn(II) complex [Zn 3 (tib) 2 (L) 3 ] with mixed ligands of 1,3,5-tris(1-imidazolyl)benzene (tib) and 4-carboxycinnamate (L 2 − ), exhibiting interesting two-fold interpenetration of triple-stranded left- ( L -) and right- ( R -) handed helical chain based 3D nets was constructed and characterized. ► Two-fold interpenetration of triple-stranded helical chain based 3D nets. ► Mixed ligands of 1,3,5-tris(1-imidazolyl)benzene and 4-carboxycinnamate. ► Fluorescence property.
