The material shows excellent coplanarity and structural regularity due to the fine planarity of DPP itself and the weak non-covalent bonding interactions existing between the three units. Two different lengths of non-conjugated side chains are introduced and this has an effect on the intermolecular chain stacking, causing the film absorption to display different characteristic properties. On the other hand, the difference in the side chains does not have a significant effect on the thermal stability and the energy levels of the frontier orbitals of the materials, which is related to the fact that the materials both feature extremely high conjugation lengths and specific molecular compositions. Microscopic investigations targeting the side chains provide a contribution to the further design of organic semiconductor materials that meet device requirements. Tests based on organic transistors show a slight difference in conductivity between the two polymers, with P2 having better hole mobility than P1. This study highlights the importance of the impact of side chains on device performance, especially in the field of organic electronics.<\/jats:p>","DOI":"10.3390\/ijms25021099","type":"journal-article","created":{"date-parts":[[2024,1,16]],"date-time":"2024-01-16T08:12:37Z","timestamp":1705392757000},"page":"1099","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Theoretical and Experimental Study of Different Side Chains on 3,4-Ethylenedioxythiophene and Diketopyrrolopyrrole-Derived Polymers: Towards Organic Transistors"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5770-1102","authenticated-orcid":false,"given":"Shiwei","family":"Ren","sequence":"first","affiliation":[{"name":"Advanced Materials Laboratory, Zhuhai-Fudan Innovation Institute, Guangdong-Macao in-Depth Cooperation Zone in Hengqin, Hengqin 519000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenqing","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Organic Solids, Institute of Chemistry, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinyang","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Organic Solids, Institute of Chemistry, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7344-2489","authenticated-orcid":false,"given":"Abderrahim","family":"Yassar","sequence":"additional","affiliation":[{"name":"Laboratory of Physics of Interfaces and Thin Films, Institut Polytechnique de Paris, 91128 Palaiseau, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8099","DOI":"10.1039\/D1TC02048J","article-title":"n-Type organic semiconducting polymers: Stability limitations, design considerations and applications","volume":"9","author":"Griggs","year":"2021","journal-title":"J.
