In the last years, several approaches to twist pyrene\u2010fused azaacenes have been developed that allow to introduce twists of different sizes. Herein, we describe the synthesis of a new set of twisted dibenzotetraazahexacenes constituted by fused pyrene and quinoxaline residues that have been distorted by introducing increasingly larger substituents on the quinoxaline residues. Their twisted structure has been demonstrated by single\u2010crystal X\u2010ray diffraction. Furthermore, absorption, fluorescence, electrochemical and theoretical studies shine light on the effects of the substituents and twists on the optoelectronic and redox properties.<\/jats:p>","DOI":"10.1002\/chem.202302002","type":"journal-article","created":{"date-parts":[[2023,9,8]],"date-time":"2023-09-08T10:03:54Z","timestamp":1694167434000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Modulating Strain in Twisted Pyrene\u2010Fused Azaacenes"],"prefix":"10.1002","volume":"29","author":[{"given":"Javier","family":"Mateos\u2010Mart\u00edn","sequence":"first","affiliation":[{"name":"POLYMAT University of the Basque Country UPV\/EHU  Avenida de Tolosa 72 E-20018 Donostia-San Sebasti\u00e1n Spain"}]},{"given":"Kais","family":"Dhbaibi","sequence":"additional","affiliation":[{"name":"POLYMAT University of the Basque Country UPV\/EHU  Avenida de Tolosa 72 E-20018 Donostia-San Sebasti\u00e1n Spain"}]},{"given":"Manuel","family":"Melle\u2010Franco","sequence":"additional","affiliation":[{"name":"CICECO \u2013 Aveiro Institute of Materials Department of Chemistry University of Aveiro  3810\u2013193 Aveiro Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5316-2594","authenticated-orcid":false,"given":"Aurelio","family":"Mateo\u2010Alonso","sequence":"additional","affiliation":[{"name":"POLYMAT University of the Basque Country UPV\/EHU  Avenida de Tolosa 72 E-20018 Donostia-San Sebasti\u00e1n Spain"},{"name":"Ikerbasque Basque Foundation for Science  Bilbao Spain"}]}],"member":"311","published-online":{"date-parts":[[2023,10,25]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/9781118011263"},{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/ar500355d"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201508384"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.accounts.8b00140"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201807004"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr050550l"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.accounts.9b00271"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr200087r"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1039\/C2CS35134J"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5CS00620A"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/ejoc.201700880"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr050550l"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5CS00620A"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6CS00623J"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.accounts.9b00144"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.accounts.9b00364"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5TC01754H"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201700271"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1039\/D0CC04735J"},{"journal-title":"Mater.
