The present invention relates to an electron deficient boron based conjugated microporous polymers (BCMP) comprising a boron appended triarylborane porous conjugated microporous polymers solid adsorbents, featuring triarylborane having Lewis acidic boron centers separated by organic linkers as integral part of polymeric network. The present invention also relates to a process for the preparation of electron deficient boron based conjugated microporous polymers. The present invention also provides a process for detection of fluoride in water or in substance which contains fluoride by using BCMP.
摘要:
A method is directed to synthesis of poly (triphenylacrylonitrite) s (PTPANs) comprisingpolycoupling dibromoarenes, internal diynes, and potassium ferrocyanide, resulting in polycoupled dibromoarenes, internal diynes, and potassium ferrocyanide; and producing poly (triphenylacrylonitrite) s (PTPANs) by catalysis of the polycoupled dibromoarenes, internal diynes, and potassium ferrocyanide with palladium acetate and sodium bicarbonate, wherein the catalysis is allowed to proceed in dimethylacetamide under nitrogen at a prescribed temperature for a prescribed time. Further, poly (triphenylacrylonitrite) s (PTPANs) is a polymer and comprises a backbone structure of P1a-d/2a-b/3, wherein x and y are integers; wherein each R is independently selected from the group consisting of 1a, 1b, 1c, and 1d; and wherein each R' is independently selected from the group consisting of 2a and 2b
