Key points
- Synthesized an isoreticular series of MOF-74 structures (IRMOF-74-I to XI) with pore apertures from 14 to 98 angstroms.
- Achieved pore expansion by increasing the phenylene rings in the MOF linker from one to eleven.
- All synthesized MOFs demonstrated robust, non-interpenetrating structures with permanent porosity.
- Pore apertures in functionalized IRMOF-74-VII and IX are large enough for natural protein entry.

Abstract
We report a strategy to expand the pore aperture of metal-organic frameworks (MOFs) into a previously unattained size regime (>32 angstroms). Specifically, the systematic expansion of a well-known MOF structure, MOF-74, from its original link of one phenylene ring (I) to two, three, four, five, six, seven, nine, and eleven (II to XI, respectively), afforded an isoreticular series of MOF-74 structures (termed IRMOF-74-I to XI) with pore apertures ranging from 14 to 98 angstroms. All members of this series have noninterpenetrating structures and exhibit robust architectures, as evidenced by their permanent porosity and high thermal stability (up to 300°C). The pore apertures of an oligoethylene glycol-functionalized IRMOF-74-VII and IRMOF-74-IX are large enough for natural proteins to enter the pores.
