Popis:	Herein, we report three different hyper-cross-linked polymers (HCPs), which were synthesised by means of copper-catalysed Huisgen 1,3-dipolar cycloaddition (CuAAC). These polymers represent novel porous networks as these are the first examples of frameworks based on a rigid pseudo-octahedral monomer (para-substituted hexaphenyl-p-xylene)—a sixfold functionalised core. The porous “click” HCPs are insoluble in common organic solvents as well as in strong acids and bases and show a high thermal stability. Their porosity was confirmed by sorption measurements using nitrogen gas at 77 K. The highest Brunauer–Emmett–Teller (BET) surface area of 725 m2 g−1 was obtained by a combination of the tetrahedral tetrakisphenylmethane-azide and the pseudo-octahedral hexaphenyl-p-xylene-alkyne (1,4-ditritylbenzene-alkyne).
