Guest-Induced 2-D Metallopolycapsular Networks Based on a 1,3-Alternate Calix[4] arene Derivative

초록

Solvothermal reactions of the calix[4]arene tetraacetic acid (H(4)CTA) with zinc nitrate in the presence of ,-diaminoalkanes afford two-dimensional metallopolycapsular networks of the formula {[Me2NH2](2)[G@(Zn-2(CTA)(2))](DMF)(2)(H2O)(4)}(n) (G=+NH3-(CH2)(n)-NH3+, 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 (+NH3-(CH2)(n)-NH3+, 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.
