| Abstract: | Herein, three new solvents induced metal-organic frameworks (MOFs), [Zn(H 2 L)H 2 O] (1), [Zn 2 (L)H 2 O] (2) and [Zn 3 (HL) 2 ]·(CH 3 CN) 2 (3) were synthesized via the solvothermal reaction procedure by using a rigid v-shaped 3,5-di (2,4-dicarboxylphenyl)pyridine (H 4 L) and Zn(II) ions. Structural analyses show that the organic ligand H 4 L adopt various degrees deprotonation (H 2 L2− for 1 ; L4− for 2 and HL3− for 3), which obtain different structures for three new MOFs: 2D layer network for 1 ; 3D dense packing structure for 2 and 3D porous structure with the pore size of 10.3 × 10.6 Å2 for 3. The gas sorption behavior of the guest-free phase 3' shows an ultra-high adsorption selectivity and affinity for CO 2 over CH 4. The experiment results provide us with a reasonable facile route for designing and synthesizing new potential gas sorption and separate materials in CO 2 purification. And the solid-state luminescence properties of 1 – 3 were measured and studied intensively at room temperature. Three new solvents induced metal-organic frameworks (MOFs), [Zn(H 2 L)H 2 O] (1), [Zn 2 (L)H 2 O] (2) and [Zn 3 (HL) 2 ]·(solvent) (3) were synthesized via the solvothermal reaction procedure by using a rigid V-shaped 3,5-di (2,4-dicarboxylphenyl)pyridine (H 4 L) and Zn(II) ions. Gas sorption of 3' displays an ultra-high adsorption selectivity and affinity for CO 2 over CH 4. And the solid-state luminescence properties of 1 – 3 were measured and studied systematically at room temperature. [Display omitted] • Solvents induced three new metal-organic frameworks (MOFs), [Zn(H 2)LH 2 O] (1), [Zn 2 (L)H 2 O] (2) and [Zn 3 (HL) 2 ]·[solvent] (3) were synthesized via the solvothermal reaction procedure by using a rigid V-shaped 3,5-di (2,4-dicarboxylphenyl)pyridine (H 4 L) and Zn(II) ions. • Structural analyses show that the organic ligand H4L adopt various degrees deprotonation (H 2 L2− for 1 ; L4− for 2 and HL3− for 3), which obtain different structures for three new MOFs: 2D layer network for 1; 3D dense packing structure for 2 and 3D porous structure with the pore 10.3 × 10.6 Å2 for 3. • Gas sorption behavior of 3′ shows an ultra-high adsorption selectivity and affinity for CO 2 over CH 4. • The solid state luminescent 1 – 3 have been explored in detail, which shows the red and blue shift in compared with H 4 L.
