Okamoto, Sentaro published the artcileSynthesis of folded H-stacking skipped π polymers consisting of different 2-substituted trimethylene tethering units and their optical and conductive property, Category: alcohols-buliding-blocks, the publication is Polymer (2021), 124037, database is CAplus.
A series of polymers P1-P4 ([-CH2CH(Z)CH2-(π conjugated unit)-]n, where Z = a bulky substituent) were synthesized via the Suzuki-Miyaura coupling polymerization and predominantly existed in their folded H-stacking form in the solution and film, which was evidenced by UV absorption, fluorescent behavior, and X-ray diffraction anal. The morphol. of the polymers in the solid states was dependent on the structure of the Z group present. The conductive nature of P1-P4 was preliminarily demonstrated on hole-only devices. Moreover, a similar onset voltage was observed for P1-P3, which all contained the same π units; however, their current-voltage characteristics were highly dependent on the Z structure. P4, which contained cross-conjugated π units, exhibited a relatively high conductivity with a lower onset requirement.
