We introduce the first example of isoreticular titanium–organic frameworks, MUV‐10 and MUV‐12, to show how the different affinity of hard Ti(IV) and soft Ca(II) metal sites can be used to direct selective grafting of amines. This enables the combination of Lewis acid titanium centers and available ‐NH 2 sites in two sizeable pores for cooperative cycloaddition of CO 2 to epoxides at room temperature and atmospheric pressure. The selective grafting of molecules to heterometallic clusters adds up to the pool of methodologies available for controlling the positioning and distribution of chemical functions in precise positions of the framework required for definitive control of pore chemistry.
