What is Enhanced Mobility Preservation of Polythiophenes in Stretched States Utilizing Thienyl-ester Conjugated Side Chain about?
Recently, diverse approaches to synthesizing intrinsically stretchable conjugated polymers have been presented, such as incorporating the conjugation break spacers or intermolecular interactions in conjugated backbones, resulting in a compromise in the charge carrier mobility. In this study, polythiophenes with flexible [2,2':5′,2'':5′′,2′′′]-quaterthiophene (QT) or rigid 2-([2,2′-bithiophen]-5-yl)thieno[3,2-b]thiophene (BTTT) backbones were engineered with ester- (E−), thienyl- (T-), and thienyl-ester-substituted (TE) side chains for an enriched amorphous content and an improved mechanical tolerance. Polythiophene with QT backbone and TE side chain (PQT-TE) represents the best mobility−stretchability properties evidenced by the polarized UV–vis absorption, grazing incidence X-ray diffraction, and surface morphological analyses. Accordingly, PQT-TE presents a higher chain conformability and crack-onset strain than QT-based polythiophene with T (PQT-T) or E (PDCBT) side chains. This improvement originated from enriched amorphous domains and enhanced backbone planarity using a biaxially extended conjugation design. PQT-TE exhibits high orthogonal mobility preservations of (64, 90)% u
