Abstract: Solvothermal reaction of adenine, 1,3,6,8-tetrakis-(p-benzoic acid)pyrene (H4TBAPy), and Zn(NO3)2 in DMF afforded a three-dimensional anionic bioMOF 1. It features onedimensional tubular channels with exposed Watson–Crick faces and nitrogen-rich purines, which endows 1 with multiple adsorption sites on its polar surface, translating into high selectivity of C2 hydrocarbons over C1. Moreover, an isostructural bioMOF 1-NH2 was synthesized by using 2-aminoadenine in place of adenine, resulting in additional amine groups pointing toward the channel cavity. The added strong adsorption sites have been demonstrated to be able to further increase the selectivity of C2 hydrocarbons over C1.
