    Highly Conductive Poly(phenylene thienylene)s:  m-Phenylene Linkages Are Not Always Bad
    摘要:
    Two isomeric polymers, which contain meta- or para-phenylene linkages between conducting segments, have been synthesized and compared by electrochemical methods. The nonconjugated poly(1,5-diacetoxy-m-phenylene tetrathienylene) (PMPT-OAc) showed similar electroactivity to the paraisomer, poly(2,5-diacetoxy-p-phenylene tetrathienylene) (PPPT-OAc), in the cyclic voltammetry and in-situ conductivity measurements. Spectroelectrochemistry showed a similar buildup of sub-band-gap electronic transitions. Deacetylation of the polymers was performed successfully by reaction with hydrazine, producing PMPT-OH and PPPT-OH. Both phenol-substituted polymers exhibited greater electroactivity than the acetoxy-substituted polymers. In addition, the phenol substituents were found to lower the "turn-on" potential in the conductivity-potential profile for PMPT-OH, but not for PPPT-OH. An alkoxy-substituted PMPT-OMe shows electroactivity similar to that of PMPT-OAc in the cyclic voltammetry, in-situ conductivity, and spectroelectrochemistry.

    A supramolecular protecting group strategy has been applied to achieve solidstate photodimerizations of olefins lined with a combination of hydrogen‐bond‐donor and ‐acceptor groups. Esters were used as protecting groups to generate head‐to‐head photodimers that were readily converted into diacids. A protected olefin equipped with a stilbene unit exhibits enhanced reactivity that is ascribed to pedal

    series of oxahelicenes composed of ortho/meta‐annulated benzene/pyridine and 2H‐pyran rings were synthesized on the basis of the cobalt(I)‐mediated (or rhodium(I)‐ or nickel(0)‐mediated) double, triple, or quadruple [2+2+2] cycloisomerization of branched aromatic hexa‐, nona‐, or dodecaynes, thus allowing the construction of 6, 9, or 12 rings in a single operation.
