High-performance solution-processable organic semiconductors (OSCs) with wide bang gap (≥3.3eV) are highly required for fabricating transparent organic thin-film transistors (OTFTs) with the inexpensive and low-temperature printed technique. Herein, in this study, we reported the newly synthesized chrysene-based OSCs (di-CR-C₁₂, mono-CR-C₁₂) with considerably large band gap of 3.70 eV, superior liquid crystallinity and solution-processed OTFTs mobility as high as 0.5 cm²/V. Such large band gap resulted in complete optical transparency of thin film in the visible-light region and good photostability. Highly ordered smectic E (SmE) phase of mono-CR-C₁₂ was the first reported case of the monoalkylated single core structure demonstrating advantageous capacity of CR backbone in stablizing Sm mesophase. Remarkably, high hole mobility exceeding 0.1 cm²/V in the bulk phase was determined by time-of-flight (TOF) technique intrinsically revealing their satisfactory carrier transport characteristics. Good solubility of mono-CR-C₁₂ enables solution-processed OTFTs with Au nanoparticles deposited at room-temperature and under ambient conditions, exhibiting good device performance with mobility up to 0.5 cm²/V. All results demonstrate that they are very promising candidates as active component for transparent electronics based on OTFTs.

具有廉价且低温印刷技术的透明有机薄膜晶体管（OTFT）的制造，对于具有宽的爆炸间隙（≥3.3eV）的高性能可溶液处理的有机半导体（OSC）提出了很高的要求。在此，在这项研究中，我们报道了新合成的基于苯酚的OSC（di-CR-C ₁₂，mono-CR-C ₁₂），其带隙相当大，为3.70 eV，具有优异的液晶性和溶液处理的OTFTs迁移率很高为0.5 cm ² / V。如此大的带隙导致薄膜在可见光区域具有完全的光学透明性和良好的光稳定性。单CR-C _12的高度近晶E（SmE）相是第一个报道的单烷基化单核结构的案例，证明了CR主链在稳定Sm中间相方面的有利能力。显着地，通过飞行时间（TOF）技术确定了在本体相中超过0.1cm ² / V的高空穴迁移率，本质上揭示了它们令人满意的载流子传输特性。mono-CR-C _12的良好溶解度使溶液处理的OTFT能够在室温和环境条件下沉积有Au纳米颗粒，并具有良好的器件性能，迁移率高达0.5 cm ² / V。所有结果表明，它们非常适合作为基于OTFT的透明电子器件的有源组件。
