characterization of several new polymers that are considered one-dimensional prototypes for the polaronicferromagnetic are reported. Synthesis involved either Wittig or Suzuki coupling to produce polymers with extended pi} systems. Oxidative doping (Isub 2} or AsFsub 5}) produces radical cations (polarons) that are stable at room temperature. Magnetic characterization of the dopedpolymers, using SQUID-based

The atmospheric chemistry of benzene oxide/oxepin, a possible
intermediate in the atmospheric oxidation of aromatic hydrocarbons,
has been investigated in a large volume photoreactor at 298 K and
atmospheric pressure using in situ FTIR spectroscopy
for the analysis. Rate coefficients of

have been determined for the
reaction of benzene oxide/oxepin with OH and NO

radicals,
respectively. Reaction with OH radicals produces almost exclusively
the (E,Z)- and (E,E)-isomers of
hexa-2,4-dienedial, whereas reaction with NO

produces
(Z,Z)-hexa-2,4-dienedial and unidentified organic
nitrates. Phenol has been observed as a major product of the thermal
decomposition, visible and UV photolysis of benzene oxide/oxepin. The
results are discussed in conjunction with the oxidation mechanisms of
aromatic hydrocarbons. The major atmospheric sinks of benzene
oxide/oxepin will be reaction with OH radicals and photolysis and,
under smog chamber conditions with high NO

concentrations,
also reaction with NO

Small Molecule Metabolite Reporters (SMMRs) for use as in vivo glucose biosensors, sensor compositions, and methods of use, are described. The SMMRs include boronic acid-containing xanthene, coumarin, carbostyril and phenalene-based small molecules which are used for monitoring glucose in vivo, advantageously on the skin.
