Pore wall fluorescence labeling of covalent organic frameworks
A novel covalent organic framework (COF) based on terphenyldiboronic acid exhibiting open pores of about 4.1 nm is presented. The pore walls of the COF could be functionalized with a fluorescent dye.

Modular assembly of porous organic cage crystals: isoreticular quasiracemates and ternary co-crystal
Co-crystallisation of helically chiral porous organic cage molecules has enabled the formation of isoreticular quasiracemates and a rare porous organic ternary co-crystal.

A quaternary-ammonium-functionalized covalent organic framework for anion conduction
A new anion conducting covalent organic framework (COF) was prepared by covalently tethering quaternary ammonium (QA) ions onto the pore walls of COF 1,3,5-triformylphloroglucinol-o-tolidine (TpBD-Me) through bromination and quaternization.

Isoreticular covalent organic frameworks for hydrocarbon uptake and separation: the important role of monomer planarity
We report three isoreticular covalent organic frameworks (COFs) sharing identical two-dimensional layered structures but with different planarity of the building monomers, leading to various crystallinities, porosities and hydrocarbon uptake and separation performances.
