A novel porous metal–organic framework, {[Zn2(L)·H2O]·3H2O·3DMAc·NH2(CH3)2}n (Zn(II)–MOF), was synthesized under solvothermal conditions using a flexible multicarboxylic acid (H5L = 3,5-bis(1-methoxy-3,5-benzene dicarboxylic acid)benzoic acid). Zn(II)–MOF contains 1D nanotubular channels of 13.8 Å × 16.4 and exhibits rare 5-connected vbk net with Schläfli symbol {45.65} topology. Notably, can adsorb toluidine blue fast effectively, trap lanthanide ions such as Eu3+ Tb3+ to sensitize their emissions in the solid state through Ln3+-exchanged approach. Furthermore, we successfully obtained white light emitting materials.
