Indacenodithiohene\u2010co\u2010thieno[3,2\u2010b]thiophene (IDT\u2010TT) and indacenodithiohene\u2010co\u2010trans\u20101,2\u2010di(2\u2010thienyl)ethylene (IDT\u2010TVT) exhibit better charge transport mobilities than indacenodithiohene\u2010co\u2010thiophene (IDT\u2010T) and indacenodithiohene\u2010co\u20103,4\u2010ethoxylene dioxythiophene (IDT\u2010EDOT), and also display superior thermoelectric properties after doping. Theoretical calculations suggest that IDT\u2010EDOT and IDT\u2010TVT have better coplanarities; the inferior performance for IDT\u2010EDOT might be due to its low molecular weight. Meanwhile, it is worth mentioning that via the synergistic effect of two dopants (CN6CP, CuTFSI), the electrical conductivities of the polymers are further improved. The XPS data shows that the coordination interaction between copper ion and the cyano groups of CN6CP introduces cupric ions into the polymer films, which leads to the increase of the doping ratio.<\/jats:p>","DOI":"10.1002\/marc.201900322","type":"journal-article","created":{"date-parts":[[2019,9,18]],"date-time":"2019-09-18T08:28:02Z","timestamp":1568795282000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Backbone
