Fluorescent homopolymers and amphiphilic block copolymers were prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization of two new styryl-type organoboron monomers; the fluorescence characteristics of PEO block copolymers in aqueous solution were studied.

widetemperaturerange. Furthermore, polymer solutions in DMSO show a reversible response to fluoride ions, which can be correlated to the presence of the Lewis acidicborinicacid groups. Upon addition of fluoride, the polymer becomes soluble because the functional R2BOH groups are converted into ionic [R2BF2]− groups, but turns insoluble again upon addition of H2O, which reverses this process.

Freeradical polymerization of B-vinyl- and B-styryl-functionalized azaborinine monomers gives organic-inorganic hybrid polymers with distinctly different materials properties compared to the corresponding carbonaceous polystyrene derivatives.

to the desired PS-B(Ar)OH functionalities. The supramolecularassembly of these polymers through Lewis acid-Lewis base interactions and reversible covalent B-O-B bond formation was investigated. Exposure of a polymer solution of 3 a to pyridine triggered spontaneous gelation, whereas 3 b only gelled upon addition of molecular sieves to favor formation of boroxane crosslinks. The crosslinking process
