## Abstract A new trifluoromethyl‐activated trifluoro monomer was successfully prepared by Pd‐initiated coupling of 1,3,5‐tribromobenzene with 4‐fluoro‐3‐trifluoromethylphenylboronic acid. 1,3,5‐Tris(4‐fluoro‐3‐trifluoromethylphenyl)benzene (**B**~**3**~) leads to several hyperbranched poly(arylene
