Extension of Conjugation Leading to Bathochromic or Hypsochromic Effects in OPV Series
Meier, Herbert,Gerold, Juergen,Kolshorn, Heinz,Muehling, Bastian
, p. 360 - 370 (2007/10/03)
Four OPV series 1-4 (a-d) with a terminal dialkylamino group as electron donor were prepared by Wittig-Horner reactions. To study the influence of the push-pull effect on the long-wavelength absorption, three of the four series contained terminal acceptor
Bathochromic or hypsochromic effects via the extension of conjugation: A study of stilbenoid squaraines
Meier, Herbert,Petermann, Ralf,Gerold, Juergen
, p. 977 - 978 (2007/10/03)
In contrast to normal conjugated oligomers, the stilbenoid squaraines 3a-d do not show a convergence of VIS/NIR absorption due to the extension of conjugation; the observed bathochromic effect in the beginning of the series is followed by a hypsochromic e
