Same architecture, different pores
Keeping the net fixed and changing the linker sets a framework’s pore size and chemistry.
A pore inside MOF-5, cut away to show the empty space. Drag to rotate.
The question
If the geometry of a framework is understood, can its pores be resized and re-functionalized in a predictable way?
What was done
A family of frameworks sharing one net but built from different linkers, so that pore size and functionality vary systematically while the architecture stays constant.
What the paper reports
The paper reports the isoreticular series with their crystal structures, and measures their capacity for methane storage.
What remains open
Predicting the pore is not the same as predicting the performance: stability, cost of the linker and behavior in mixtures decide whether a designed pore becomes a useful material.
