    • 2BBr showed clean attachment of boron at the quinolate moiety without cleavage of the methoxy group. Moreover, the polymer data showed no unusual signals in the NMR spectra or signs of cross-linking by GPC. Presumably, the hydroxy group is considerably more reactive than the methoxy moiety and, since the initial attack of boron involves Lewis acid-Lewis base adduct formation, the presence of the pyridyl nitrogen in β-position is expected to further favor reaction at the quinolate OH group.

    • Sneddon, L. G.; Pender, M. J.; Forsthoefel, K. M.; Kusari, U.; Wei, X. J. Eur. Ceram. Soc. 2005, 25, 91-97. Formation of ceramic residues is one possible explanation for the low C,H,N data of the polymers. Analysis of the TGA residue of PSBPhQ-H by X-ray diffraction yielded data reminiscent of amorphous material. Small amounts of residual solvents or less than 100% boron functionalization also have to be considered, and slightly lower absorbances in comparison to the model systems support this possibility. However, we could not conclusively correlate the elemental analysis results to one single factor, and indeed multiple factors may contribute.
