  Synthesis and properties of a sterically encumbered poly(thienylene vinylene): <BR>poly[<i>E</i>-1,2-(4,4prime-dihe×yl-2,2prime-dithienyl)ethylene]

  摘要：

  Electrically conducting poly[E-1,2-(4,4'-dihexyl-2,2'-dithienyl)ethylene] was synthesized and structurally characterized by UV-visible, H-1 NMR, and FTIR spectroscopy. The head-to-head arrangement of the alkylthiophene dyads directly affects the UV-visible, photoluminescence, and electroluminescence maxima of the polymer. The conductivity of the doped polymer was measured to be similar to 2 S cm(-1) and the stability of the oxidized polymer possessing various dopants was compared. UV-visible irradiation of PDHDTE rendered the films :insoluble and photolithography was used to produce micron-size images. FTIR was used to monitor the photoproducts during photolysis of PDHDTE. Mechanisms of photooxidation were proposed, based on the photoproducts observed.
