nitrogen, after one week. On/off ratios were stable in air throughout. We also investigated transistorstability to gate biasstress. The transistor on hexamethlydisilazane (HMDS) is more stable than that on OTS with mobility comparable to amorphous Si TFTs. VT shifts caused by ON (30 V) and OFF (–20 V) gate biasstress for the HMDS samples for 1 hour were 1.79 V and 1.27 V under N2, respectively, and relaxation
新合成了N,N'-双(3-(全氟丙基)丙基)-1,4,5,8-萘四甲酸二酰亚胺(8-3-NTCDI),以及相关的氟辛基烷基-NTCDI和烷基-NTCDI。在经过十八烷基三甲氧基硅烷(OTS)处理的Si / SiO 2衬底上的基于8–3–NTCDI的有机薄膜晶体管(OTFT)显示出表观电子迁移率接近0.7 cm 2 V -1 s -1在空中。氟辛基乙基-NTCDI(8–2–NTCDI)和氟辛基丁基–NTCDI(8–4–NTCDI)即使其化学结构略有不同,其性能也明显较差,并且非氟化癸基和十一烷基NTCDI在空气中无法正常运行。通过原子力显微镜,在120°C的温度下沉积在基板上的8–3‐NTCDI活性层形成了晶粒尺寸>4μm的多晶膜。流动性在空气中稳定了一周。在空气中放置100天后,三个OTFT的平均迁移率从0.62降至0.12 cm 2 V -1 s -1,但此后保持稳定。阈值电压(V T)在一周后在空气中增加了15

A dyad (C3–NI) based on corrole and naphthalenebisimide has been synthesized and its photoreactivity compared to that of the model component corrole (C3) and naphthalenebisimide (NI) in solvents of different polarity: toluene (TL) and dichloromethane (DCM). The major emitting species in NI solutions, in TL, is identified as a dimeric species (λ = 470 nm, τ = 2.3 ns) but traces of monomer can also

1,4,5,8-Naphthalene bisimides react as dipolarophiles with in situ formed azomethine ylides. Double 1,3-dipolar cycloaddition is followed by unique ring rearrangement and leads to the formation of two six-membered rings. The formation of hexacyclic products is rationalized based on DFT calculations.
