  The synthesis of π-electron molecular rods with a thiophene or thieno[3,2-b]thiophene core unit and sulfur alligator clips

  摘要：

  A series of short oligo(p-phenylene-ethynylene)- and oligo(p-phenylenevinylene)-type molecular rods with an electronically rich thiophene or thieno[3,2-b]thiophene core unit and sulfur anchoring groups (AcS-, t-BuS-) at the termini have been synthesised using Sonogashira coupling or Homer-Wads-worth-Emmons (E)-olefination methodology. The collection of linear/bent, conjugated/cross-conjugated systems has been characterised by UV-vis and fluorescence spectroscopy, optical/calculated HOMO-LUMO gaps and calculated excitation energies.
