complexes of new soluble symmetrical octa(m-trifluoromethylphenyl) or octa(m-trifluoromethylphenoxy) substituted 2,3-naphthalocyanines [(m-CF3Ph)8NcM] or [(m-CF3PhO)8NcM]} in good yields is described in detail. The structures of the synthesized compounds were verified by UV/Vis and 1H and 13C NMR spectroscopy, as well as by mass spectrometry. The good solubilities of the prepared compounds in toluene

We report the synthesis of a series of 2,3,5,6-tetraalkoxydibenz[a,c]anthracenes bearing substituents (H, OCH3, or CN) in the 11- and 12-positions and an investigation of their liquid-crystalline properties. The synthesis involved Suzuki coupling of the appropriate dibromonaphthalene and boronate ester, followed by an oxidative cyclization. Compounds 4 and 5, bearing OCH3 and H, respectively, do not
The fabrication of printed electronic circuits using solution-based electroconductive materials at low temperature is essential for the realization of modern printed electronics including transistors, photovoltaic cells, and light-emitting devices. Despite the progress in the field of semiconductor solution materials, reliable electrodes are always fabricated by a vacuum deposition process resulting in only partially solution-processed devices. In this paper, we show that planar phthalocyanine-conjugated Au nanoparticles (NPs) significantly improve the interparticle-carrier-transport properties. The deposition of a solution of the Au NPs under ambient conditions results in an electroconductive metallic thin film without further post-treatment. Maximum conductivity reaches >6600 S cm−1 and the conductivity remains unchanged for at least 1 year under ambient conditions. The all-solution-processed organic field-effect transistor (OFET) fabricated under ambient conditions exhibits mobility values as high as 2 cm2 V−1 s−1, the value of which is comparable to OFET devices having vacuum-deposited Au electrodes.
使用溶液型导电材料在低温下制作印刷电子电路,对于实现包括晶体管、光伏电池和发光器件在内的现代印刷电子产品至关重要。尽管在半导体溶液材料领域取得了进展,但可靠的电极始终是通过真空沉积工艺制造的,因此只能制造出部分溶液处理的器件。在本文中,我们展示了平面酞菁共轭金纳米粒子(NPs)可显著改善粒子间载流子传输特性。在环境条件下沉积 Au NPs 溶液后,无需进一步后处理即可形成导电金属薄膜。最大电导率大于 6600 S cm-1,并且在环境条件下至少 1 年电导率保持不变。在环境条件下制造的全溶液处理有机场效应晶体管(OFET)的迁移率值高达 2 cm2 V-1 s-1,与真空沉积金电极的 OFET 器件相当。
