Here　we　expand　our　recently　reported　Bristol-Xi＇an　Jiaotong　(BXJ)　approach　using　simple　salts　to　fine-tune　the　porosity　of　conjugated　microporous　materials　synthesized　by　various　reaction　approaches,　including　Buchwald-Hartwig　(BH),　Sonogashira-Hagihara,　oxidative　coupling　and　Suzuki　cross-coupling.　The　surface　area　and　the　porosity　of　the　produced　conjugated　microporous　polyanilines　(CMPAs)　acquired　from　the　non-salt-added　BH　coupling　are　optimized　by　the　addition　of　inorganic　salts.　BXJ-salt　addition　provides　a　facile　route　to　radically　improve　the　BET　surface　area　from　28　to　901　m(2)　g(-1)　for　PTAPA　and　from　723　m(2)　g(-1)　to　1378　m(2)　g(-1)　for　PAPA　in　a　controllable　manner.　In　addition,　the　surface　area　shows　a　gradual　decrease　with　an　increase　in　the　ionic　radius　of　salts.　We　furthermore　show　high　compatibility　of　this　approach　in　the　synthesis　of　typical　CMPs,　further　increasing　the　surface　area　from　886　to　1148　m(2)　g(-1),　981　to　1263　m(2)　g(-1),　and　35　to　215　m(2)　g(-1)　for　CMP-1,　PTCT　and　p-PPF,　respectively.　More　importantly,　the　BXJ　approach　also　allows　the　broad　PSD　of　the　CMPs　to　be　narrowed　to　the　microporous　range　only,　mimicking　COFs　and　MOFs.　With　the　porosity　optimized,　CO2　uptakes　are　dramatically　improved　by　＞300%　from　0.75　mmol　g(-1)　to　2.59　mmol　g(-1)　for　PTAPA　and　from　2.41　mmol　g(-1)　to　2.93　mmol　g(-1)　for　PAPA.　Careful　addressing　of　Hansen　solubility　parameters　(HSPs)　of　solvents　and　resulting　polymers　through　salt　addition　has　the　potential　to　become　an　important　design　tool　for　the　preparation　of　fully　tuneable　porous　materials.　We　are　currently　exploring　further　methods　to　tune　both　structure　and　function　in　a　wide　range　of　organic　porous　materials.
