摘      要：The coordination of cucurbit[5]uril (Q[5]) with lanthanide cations (Ln3+), in the presence of Cu2+ cations, led to the formation of 2D-network coordination polymers, which have been investigated using single crystal X-ray diffraction. Experimental results revealed that crystals were only readily affordable for the systems involving the lighter lanthanide cations (La3+, Ce3+, Pr3+, Sm3+, Eu3+ and Tb3+), with all six Ln3+-Q[5] complexes (1 ~ 6) exhibiting similar coordination mode at the cucurbit[5]uril (Q[5]), and forming 2D-network coordination polymers with a 2D supramolecular assembly. One complex was found to detect Adenine (A) and Uracil (U) with high selectively. © 2023, The Authors. All rights reserved.
