Macromolecular Chemistry and Physics. ISSN. 1022-1352. Vol. 216, N.º 5 (2015), pp. 519-5291022-13521521-3935http://hdl.handle.net/10400.21/5846Electron-acceptor units, combined with bithiophene substituted with flexible chains end-functionalized with cross-linkable moieties, provide soluble donor-acceptor-donor (DAD) it-conjugated oligomer-type molecules with cross-linking ability and broad absorption in the visible spectrum. A study on the cross-linking conditions of the new oligomers to yield insoluble polymer networks is presented, including conditions for obtaining polymer films over poly(3,4-ethylenedioxythiophene):polystyrene sulfonate-covered substrates. The combination of the DAD molecular design and cross-linking functionality opens prospects for applications in solution-processed small-molecule solar cells with morphologically-stable organic layers.engconjugated oligomerscross-linkingmacromonomersorganic photovoltaicscross-structure-property relationsjournal article10.1002/macp.201400527
