Adapted from ref. ) A poly(aniline boronic acid)-based conductimetric sensor for dopamine consisting of an interdigitated microarray electrode coated with poly(aniline boronic acid) has also been developed by the Fabre team. 42 Boronic acid-containing polyaniline has also been utilized in diabetes-related research. One such polymer (23) (Fig. 43 The polymer was prepared by the copolymerization of aniline with 3-aminophenylboronic acid using 10 mM (NH4)S2O8 in 1 M HCl. 2.

112 Wagner and co-workers have reported the synthesis of ferrocene-bridged tris(1-pyrazolylborate) oligomeric systems (80) (Fig. 113,114 N B Fe N N N N N N N M N N N B N n 80 Figure 49 Ferrocene-bridged tris(1-pyrazolylborate) oligomeric systems (80). (Adapted from ref. ) Pyrazabole ligands have been introduced into fluorescent organoboron polymers (81) (Fig. 115 The number-average molecular weights (9000–34,000) of the polymers obtained by this method were comparatively higher than that of similar polymers obtained from hydroboration reactions.

The thermal stabilities of the cross-linked networks were analyzed thermogravimetrically by heating to 1000°C in N2. For a given siloxane:carborane:diacetylene ratio, the char yields were discovered to be about 4–6% higher for the blocky type of copolymers when compared to the alternating type of copolymers. The synthesis of block polymers of diacetylene–silarylene and diacetylene– carboranylenesiloxane polymers (99a–e) (Fig. 129 These polymers are a hybrid between the carboranylenesiloxane and silarylene-siloxane polymers and have high char yields (up to 85%) at 1000°C in N2 and in air, reflecting the thermal stabilizing effects of the carborane and aromatic units in the polymeric backbone.
