Unprecedented interweaving of single-helical and unequal double-helical chains into chiral metal–organic open frameworks with multiwalled tubular structures

Abstract

Two novel chiral metal–organic open frameworks with unprecedented multiwalled tubular channels and interweaving of single-helical and unequal double-helical units were reported, which possess novel four-connected 428310 topology and represent the first examples of functional metal–organic frameworks based on both flexible tripodal and flexible bisdentate ligands.
