Photochromism and Electrical Transport Characteristics of a Dyad and a Polymer with Diarylethene and Quinoline Units

The synthesis of a series of photochromic compounds incorporating a phenylquinoline unit and the
photophysical and electric transport properties are described. The dyad and polymer with a quinoline
unit show a high quantum yield due to the enforced antiparallel conformation of the dithienylethene
moieties. High carrier conductivity was observed in the closed form of the diarylethene with a
phenylquinoline unit.
