Permanently porous cycloparaphenylene nanohoops <i>via</i> supramolecular engineering.

ABSTRACT: Cycloparaphenylenes, also called carbon nanohoops, are a class of strained macrocycles recognized for their unique size-dependent optoelectronic properties, rich host-guest chemistry, and resemblance to carbon nanotubes. In this work, we establish carbon nanohoops as versatile tectons for permanently porous molecular crystals with well-defined supramolecular architectures and novel functionality. Using fluorinated nanohoops as precursors, we have synthesized seven new difluorodibenzodioxin-, methoxy-, and catechol boron bromide-functionalized derivatives. Structural characterization by single crystal X-ray and electron diffraction reveals porous structures stabilized by diverse noncovalent interactions, including π-π, CH-π, and boron-π interactions. In difluorodibenzodioxin nanohoops, robu
