Three Resorcin[4]arene-Based Two-Dimensional Zn(II) Supramolecular Isomers Synthesized via a Structure-Directing Strategy for Knoevenagel Condensation

“…Structure-directing agents (SDAs) are becoming an active research area today, particularly in the fields of zeolite or molecular sieve syntheses. − SDAs seldom appear in the final backbone of architectures but act as templates, space-filling molecules, or counterions for charge balance in the pores. − Commonly used SDAs include organic/inorganic acids, polyoxometalatic acids, organic amines, and solvent molecules. − Recently, SDAs began to be employed for the preparation of coordination polymers (CPs). , By analyzing previous works, we found that rational utilization of SDAs could result in different structures upon adjustment of the dimensions of CPs. − …”

“…It is an enormous challenge to design a supramolecular isomerism system with SDAs. 17−22 On the basis of functionalized resorcin [4]arenes, plenty of CPs with unique architectures and diverse properties have been reported. 23−29 Although POMs as SDAs have been applied in the syntheses of resorcin [4]arene-based CPs, small organic acids as SDAs for the syntheses of resorcin [4]arene-based supramolecular isomers have never before been reported.…”

“…34−36 In this regard, CPs were often used as heterogeneous catalysts because they have insoluble features and uniformly distributed metal ions in their structures. 37,38 Because of the considerations described above, we focused on the construction and properties of resorcin [4]…”
