A novel method for single-crystal (SC) growth, called "indirect sublimation," was successfully used to grow crystals of 1,3,6,8-tetrakis(methylthio)pyrene (MT-pyrene), MS-pyrene, rubrene, DNTT, and pentacene. High-coverage uniform crystals were obtained for MT- and MS-pyrene, which were transferred to a substrate using a rubbing machine to create a high-coverage multi-SC (MSC) film for device applications. MSC film-based organic field-effect transistors (OFETs) using MT-pyrene showed good on/off characteristics and high carrier mobilities (>20 cm2 V-1 s-1), comparable to SC devices (30 cm2 V-1 s-1).The development of novel high-mobility organic semiconductor materials was also performed, with a focus on designing molecules with brickwork crystal structures similar to MT-pyrene. A simulation algorithm was developed to accurately predict known brickwork-related crystal structures (MT- and MS-pyrene), and it was applied to the design of 1,3,8,10-tetrakis(methylthio)peropyrene (MT-peropyrene), which was synthesized and evaluated. SC-OFETs made with MT-peropyrene showed very high mobilities (30 cm2 V-1 s-1).Further optimization of the indirect sublimation method for MT-peropyrene and other materials, as well as fabrication of OFET-based devices such as pseudo-CMOS inverters, is ongoing. Additionally, novel material screening and development are being performed.

一种称为“间接升华”的单晶 (SC) 生长新方法已成功用于生长 1,3,6,8-四（甲硫基）芘 (MT-芘)、MS-芘、红荧烯、 DNTT 和并五苯。 MT-和MS-芘获得了高覆盖率均匀晶体，使用摩擦机将其转移到基材上，形成用于器件应用的高覆盖率多SC (MSC) 薄膜。使用 MT-芘的基于 MSC 薄膜的有机场效应晶体管 (OFET) 显示出良好的开/关特性和高载流子迁移率 (>20 cm2 V-1 s-1)，与 SC 器件 (30 cm2 V-1 s-1) 相当。 1).新型高迁移率有机半导体材料的开发，重点是设计具有类似于MT-芘的砖砌晶体结构的分子。开发了一种模拟算法来准确预测已知的砖砌相关晶体结构（MT-和MS-芘），并将其应用于1,3,8,10-四（甲硫基）芘（MT-芘）的设计，对其进行了合成和评估。用MT-peropyrene制成的SC-OFET表现出非常高的迁移率（30 cm2 V-1 s-1）。进一步优化MT-peropyrene和其他材料的间接升华方法，以及基于OFET的器件的制造，例如伪-CMOS反相器，正在进行中。此外，新材料的筛选和开发正在进行中。
