Application

Poly(4-vinylpyridine-co-styrene) can be used:
  • As a precursor in the preparation of ionic polymer with pendant photochromic moieties by reactingwith1,3,3-trimethyl-6′-bromohexyloxyspiro[2H]-indol-2,3′-[3H]-naphth[2,1-b][1,4]oxazine.
  • As permselective membrane in the preparation of composite electrodes for glucose sensing.
  • To prepare mixed redox polymer [RuIII(edta)(OH2)(py)]2[RuII(NH3)5(py)], which can switch into six redox states.

An ionic polymer with pendant photochromic moieties was prepared by the reaction of poly(4-vinylpyridine-co-styrene) and 1,3,3-trimethyl-6'-bromohexyloxyspiro[2H]-indol-2,3'-[3H]-naphth[2,1-b][1,4]oxazine. The photochromic reaction in question is caused by the reversible heterolytic cleavage of the C(spiro)-O bond under UV irradiation, yielding the colored form that
