Microporous polymer networks (MPNs) attract strongly increasing attention today due to the prospective applications in gas storage/separation, catalysis and sensor devices, or as superabsorbers for hydrophobic solvents or oil traces in aqueous media.
Structure-property relationships between the employed tectons and the resulting polymer networks were established. It is shown that higher rigidity and stiffness of the tectons lead to increased specific BET-surface areas. Low rotational freedom of building blocks of the polymer networks as well as reduction of π-π interactions or charge-transfer interactions e. g. with enclosed metal residues have a positive effect on the measured photoluminescence quantum yield (PLQY). Moreover, it is possible to control the porous structure of the resultant networks by the choice of the reaction conditions (catalyst, temperature, solvent), and by varying the monomer-solvent ratio.
