Starting frommononitrotetrakis(iodophenyl)methane as monomer, we report the preparation of the first pre‐functionalised porous aromaticframeworks (PAFs) and their application as supports for organometallic catalysts. Neutral coordinate imino‐pyridine Schiff base (PAF‐NPy) or chiral bis‐amino (PAF‐NPro) ligands were obtained by post‐synthetic treatment of PAF‐NH2 and treated with copper(I) or rhodium(I)

Three chiral robust diene-based porous organic frameworks (POFs) are prepared. POF-1 is shown to be an efficient heterogeneous catalyst after metallation for asymmetric conjugation addition with up to 93% ee, and it can also function as a new chiral stationary phase for gas chromatographic separation of racemates.
Azo-linked porous organic polymers: robust and time-efficient synthesis<i>via</i>NaBH<sub>4</sub>-mediated reductive homocoupling on polynitro monomers and adsorption capacity towards aniline in water
A library of novel, multidimensional alkoxyamines was synthesized in a multistep procedure from commercial precursors with very good yields. The easy procedures lead to linear, trigonal planar, square planar, and tetrahedral shaped alkoxyamines. These building blocks can be used for classical nitroxide mediated polymerization leading to star‐shaped polymers or nitroxide exchange reactions resulting
