    Abstract: Poly(anilineboronic acid)/phosphate nanoparticle dispersions are produced in high yields using the reactivity of the boronic acid moiety with phosphate in the presence of fluoride. The poly(anilineboronic acid)/phosphate dispersions have been characterized using spectroscopic, microscopic and electrochemical techniques. According to 11B NMR studies, the formation of anionic tetrahedral boronate group in phosphoric acid in the presence of fluoride forms the basis of self-doped, stabilized PABA nanoparticle dispersion. Transmission electron microscope images show that 25-50 nm diameter PABA nanoparticles are formed under these conditions. UV-vis, FT-IR-ATR spectroscopic and cyclic voltammetric results confirm the formation of the conducting form of PABA.

  • Publication number: 20040254324
    Abstract: A method for making a polymer containing a first repeat unit having formula: —Ar—N(R)—Ar—(N(R′)—Ar)x— which may be substituted or unsubstituted where x is 0 or 1; each Ar is the same or different and independently is a substituted or unsubstituted aryl or heteroaryl group and R and R′ each is hydrogen or a substituent group and a second repeat unit that is the same or different from the first repeat unit and comprises a substituted or unsubstituted, aryl or heteroaryl group. The polymer is made by Suzuki polymerisation wherein the monomer from which repeat unit (1) is derived comprises one or two reactive boron groups.
