•High-molecular-weight CPIs were prepared using 3,3′-BPDA and fluorinated diamines.•3,3′-BPDA-derived CPIs showed high d-spacing values due to the twisted structures.•3,3′-BPDA-derived CPIs were highly soluble in common organic solvents.•3,3′-BPDA-derived CPIs exhibited high Tg of 287–414 °C and good thermal stability.•3,3′-BPDA-derived CPIs showed λ0 of <370 nm, T450 of 80–89%, and YI of 1.4–13.4.
In this work, 2,2′,3,3′-biphenyltetracarboxylic dianhydride (3,3′-BPDA) was exploited to produce colorless polyimides (CPIs), and their properties were systematically investigated. High-temperature polycondensation of 3,3′-BPDA with fluorinated diamines enabled the synthesis of CPIs with high molecular weights. The resulting CPIs displayed deficient chain packing owing to the steric hindrance and suppressed formation of charge transfer complexes (CTC), as confirmed by the interchain distances (5.9–6.7 Å). These CPIs were highly soluble in common organic solvents due to the enlarged interchain distances. Depending on the chain rigidity, the glass transition temperatures of the CPIs ranged from 287 to 414 °C. More importantly, these CPIs exhibited outstanding optical properties, with a cut-off wavelength of 355–370 nm, transmittance at 450 nm of 79.6–89.2%, and yellow index of 1.4–13.4.</description><identifier>ISSN: 0014-3057</identifier><identifier>EISSN: 1873-1945</identifier><identifier>DOI: 10.1016/j.eurpolymj.2022.111528</identifier><language>eng</language><publisher>Oxford: Elsevier Ltd</publisher><subject>2,2′,3,3′-Biphenyltetracarboxylic dianhydride ; Chains ; Charge transfer ; Chemical synthesis ; Colorless polyimide ; Cut off wavelength ; Diamines ; Dianhydrides ; Fluorinated diamine ; Fluorination ; Glass transition temperature ; Heat transfer ; High temperature ; Mechanical properties ; Molecular weight ; Optical properties ; Optical transparency ; Polyimide resins ; Steric hindrance</subject><ispartof>European polymer journal, 2022-10, Vol.179, p.111528, Article 111528</ispartof><rights>2022 Elsevier Ltd</rights><rights>Copyright Elsevier BV Oct 5, 2022</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c343t-5928665b8bfbfac8a48dd64211505ac37517a87b8d2523f4e61dbd845e10544e3</citedby><cites>FETCH-LOGICAL-c343t-5928665b8bfbfac8a48dd64211505ac37517a87b8d2523f4e61dbd845e10544e3</cites><orcidid>0000-0001-6031-0025</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://dx.doi.org/10.1016/j.eurpolymj.2022.111528$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>315,781,785,3551,27926,27927,45997</link.rule.ids></links><search><creatorcontrib>Xu, Yuanzhen</creatorcontrib><creatorcontrib>Zhang, Mengru</creatorcontrib><creatorcontrib>Pang, Yuanyuan</creatorcontrib><creatorcontrib>Zheng, Tianyue</creatorcontrib><creatorcontrib>Zhang, Li</creatorcontrib><creatorcontrib>Wang, Zhen</creatorcontrib><creatorcontrib>Yan, Jingling</creatorcontrib><title>Colorless polyimides from 2,2′,3,3′-biphenyltetracarboxylic dianhydride and fluorinated diamines</title><title>European polymer journal</title><description>[Display omitted]
