资源简介：
Reactions of 4,4-dichlorodithienogermoles
with sodium, followed
by reprecipitation of the organic products, provided poly(dithenogermane-4,4-diyl)s.
The absorption edges were at lower energies than that of a monomeric
dithienogermole derivative. Comparison of the optical properties of
the polygermanes with those of their respective polygermoxanes (prepared
by oxidizing the polygermanes) and copolymers composed of dithienogermole
and di-n-butylgermane units indicated that the red-shifted
absorption edges were likely associated with conjugation of the dithienogermole
π-orbital with the polygermane backbone σ-orbital. This
was further supported by optical studies on the dimeric compound 4,4′-bis(4-ethyldithienogermole)
and density functional theory calculations on tetrameric models.
