Simple　inorganic　salts　are　used　to　tune　N-containing　conjugated　microporous　polymers　(CMPs)　synthesized　by　Buchwald-Hartwig　(BH)　cross-coupling　reactions.　Poly(triphenylamine),　PTPA,　initially　shows　a　broad　distribution　of　micropores,　mesopores,　and　macropores.　However,　the　addition　of　inorganic　salts　affects　all　porous　network　properties　significantly:　the　pore　size　distribution　is　narrowed　to　the　microporous　range　only,　mimicking　COFs　and　MOFs;　the　BET　surface　area　is　radically　improved　from　58　m(2)　g(-1)　to　1152　m(2)　g(-1);　and　variations　of　the　anion　and　cation　sizes　are　used　to　fine-tune　the　surface　area　of　PTPA,　with　the　surface　area　showing　a　gradual　decrease　with　an　increase　in　the　ionic　radius　of　salts.　The　effect　of　the　salt　on　the　physical　properties　of　the　polymer　is　attributed　to　adjusting　and　optimizing　the　Hansen　solubility　parameters　(HSPs)　of　solvents　for　the　growing　polymer,　and　named　the　Beijing-Xi＇an　Jiaotong　(BXJ)　method.
