In this study, we explored a wide range of green solvents to process the semiconductor layer TIPS-PEN (6,13-bis(triisopropylsilylethynyl)pentacene), as well as to demonstrate potential generality, using several p- and n-type organic semiconductors, for the fabrication of organic thin-film transistors (OTFTs). Our data demonstrate that several different solvents enable good semiconductor film-forming morphologies and optimized TIPS-PEN TFT mobilities of ∼0.5–2 cm² V⁻¹ s⁻¹, thus surpassing those of toxic chlorinated options. Furthermore, we utilized a green cellulose cinnamate-gate dielectric to fabricate TIPS-PEN OTFTs, where both the semiconductor and the dielectric were processed using green solvents demonstrating the feasibility of a more sustainable OTFT technology.

用于有机薄膜晶体管加工的绿色溶剂

在这项研究中，我们探索了多种绿色溶剂来处理半导体层TIPS-PEN（6,13-双（三异丙基甲硅烷基乙炔基）并五苯），并展示了使用多种p型和n型有机半导体的潜在通用性。，用于制造有机薄膜晶体管（OTFT）。我们的数据表明，几种不同的溶剂可实现良好的半导体成膜形态，并优化了〜0.5–2 cm ² V ^-1 s ^-1的TIPS-PEN TFT迁移率，因此超过了有毒氯化物的选择。此外，我们利用绿色的肉桂酸纤维素栅电介质来制造TIPS-PEN OTFT，其中半导体和电介质均使用绿色溶剂进行了加工，证明了更可持续的OTFT技术的可行性。
