Catarineu, Noelle R.; Schoedel, Alexander; Urban, Philipp; Morla, Maureen B.; Trickett, Christopher A.; Yaghi, Omar M. published the artcile< Two Principles of Reticular Chemistry Uncovered in a Metal-Organic Framework of Heterotritopic Linkers and Infinite Secondary Building Units>, COA of Formula: C18H22BNO3, the main research area is zinc MOF heterotritopic benzoate benzosemiquinonate oxidopyridine linker solvothermal preparation; crystal structure zinc MOF heterotritopic benzoate benzosemiquinonate oxidopyridine linker; helicity zinc MOF heterotritopic benzoate benzosemiquinonate oxidopyridine linker.
Structural diversity of metal-organic frameworks (MOFs) was largely limited to linkers with at most two different types of coordinating groups. MOFs constructed from linkers with three or more nonidentical coordinating groups were not explored. Here, the authors report a robust and porous crystalline MOF, Zn3(PBSP)2 or MOF-910, constructed from a novel linker PBSP (phenylyne-1-benzoate, 3-benzosemiquinonate, 5-oxidopyridine) bearing three distinct types of coordinative functionality. The MOF adopts a complex and previously unreported topol. termed tto. The authors’ study suggests that simple, sym. linkers are not a necessity for formation of crystalline extended structures and that new, more complex topologies are attainable with irregular, heterotopic linkers. This work illustrates two principles of reticular chem.: first, selectivity for helical over straight rod secondary building units (SBUs) is achievable with polyheterotopic linkers, and second, the pitch of the resulting helical SBUs may be fine-tuned based on the metrics of the polyheterotopic linker.
