Solvothermal reactions of the calix[4]arene tetraacetic acid (H 4 CTA) with zinc nitrate in the presence of α,ω‐diaminoalkanes afford two‐dimensional metallopolycapsular networks of the formula {[Me 2 NH 2 ] 2 [G@(Zn 2 (CTA) 2 )] ⋅ (DMF) 2 ⋅ (H 2 O) 4 } n (G= + NH 3 –(CH 2 ) n –NH 3 + , n =2, 3, 4; DMF= N , N ‐dimethylformamide). These metallopolycapsular networks are built up of metallocapsules that consist of two CTA and two Zn II ions. Short alkanediyldiammonium ( + NH 3 –(CH 2 ) n –NH 3 + , n =2, 3, 4) guest ions are accommodated in each capsule of the metallopolycapsular network through a variety of supramolecular interactions. The thermal behaviours and the solid‐state photoluminescent properties of these complexes were also investigated.
