In the NMR and UV-vis studies, the association constants (log K11) for the host-guest interactions of L with the dinitrile guests are C2 (4.75) C3 (4.17) ≫ C4 (2.85) C5 (2.45) C6 (too small), indicating that the shorter guests C2 or C3 interact more strongly than longer ones due to the confined interior space of L. Taken collectively, the C2 and C3 guests with proper size-matching promote the formation of coordination polymers and vice versa, suggesting that the guest size could be a controlling factor.D
