We report here a one‐step method for synthesizing multi‐component and in‐situ‐formed homochiral spiroborate‐ester‐based metal‐organic framework CPM‐B1. This unique material successfully integrates COF fragment spiroborate ester within the MOF and simultaneously incorporate homochirality and helicity. In addition, CPM‐B1 is a rare example of framework materials that results from the cooperative assembly of three charge‐complementary cations: +1 (lithium), +2 (cobalt), and +3 (boron). The sophistication of the co‐assembly is further highlighted by the three structural roles of lithium ions. This unique structure contributes to its multi‐functional properties such as ionic conductivity and catalytic activity for oxygen reduction reaction (by CPM‐B1 carbonized material) and provides a new path to develop MOF materials with complex secondary building units and multi‐functional applications.
