Solvent-based deposition techniques for fabrication of organic field-effect transistors (OFETs) generally require orthogonal solvents for deposition of a conjugated polymer layer on a polymer gate insulator layer. Here, we found significantly reduced dissolution rate of the polymeric film in the same solvent after casting a homegeneous polymerization solution of para-bis(3-aminopropyl)hexaisobutyl-substituted T₈ cage (1) with terephthalaldehyde. The limited dissolution rate in the solvent provided enough chance for fabrication of a regioregular poly(3-hexylthiophene-2,5-diyl) (P3HT) layer on the present polymer films without using an orthogonal solvent. The rheological properties indicate that physical interaction between the polymer chains provides the significantly reduced dissolution rate after the deposition onto a substrate without any cross-linking treatments.

适用于使用相同溶剂对双层器件进行溶液处理的串上珠状聚（偶氮甲碱）

用于制造有机场效应晶体管 (OFET) 的基于溶剂的沉积技术通常需要正交溶剂来在聚合物栅极绝缘层上沉积共轭聚合物层。在这里，我们发现在浇铸对-双（3-氨基丙基）六异丁基取代的 T ₈笼 ( 1) 与对苯二甲醛。在溶剂中有限的溶解速率为在不使用正交溶剂的情况下在本聚合物薄膜上制造区域规则的聚 (3-己基噻吩-2,5-二基) (P3HT) 层提供了足够的机会。流变学特性表明，聚合物链之间的物理相互作用在沉积到基材上后显着降低了溶解速率，而无需任何交联处理。
