A TT-terminal ladder-type donor is generally a better molecular design than the corresponding T-terminal ladder-type isomer for the development of new A–D–A NFEAs.
一个TT-末端梯形供体通常比相应的T-末端梯形异构体更适合开发新的A-D-A非完美吸收体。

The present invention pertains generally to the field of therapeutic compounds. More specifically the present invention pertains to certain 2-amino-N-(amino-oxo-aryl-λ6- sulfanylidene)acetamide compounds (referred to herein as ANASIA compounds) that, inter alia, inhibit (e.g., selectively inhibit) bacterial aminoacyl-tRNA synthetase (aaRS) (e.g., bacterial leucyl-tRNA synthetase, LeuRS). The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit (e.g., selectively inhibit) bacterial aminoacyl-tRNA synthetase; to treat disorders that are ameliorated by the inhibition (e.g., selective inhibition) of bacterial aminoacyl-tRNA synthetase; to treat bacterial infections; etc.

with tetrathienoacene (TTA) as the central core end-capped with 5-hexyl-2-thiophene, (Hex-T)2-TTA, and 4-hexyl-phenyl, (Hex-Ph)2-TTA, have been synthesized and investigated for organic field effect transistor (OFET) applications. The novel TTA derivatives were characterized by thermal gravimetric analysis, differential scanning calorimetry, UV–Vis spectroscopy, and cyclic voltammetry as well as studied
两种新颖的有机半导体,以四硫杂并苯(TTA)为中心核,末端被5-己基-2-噻吩(Hex-T)2 -TTA和4-己基苯基(Hex-Ph)2 -TTA封端,已经对有机场效应晶体管(OFET)应用进行了合成和研究。通过热重分析,差示扫描量热法,紫外可见光谱和循环伏安法对新型TTA衍生物进行表征,并通过密度泛函理论计算进行了研究。制备并表征了具有溶液和真空沉积活性层的两种类型的OFET。两种TTA衍生物均在OFET中表现出电致发光,而(Hex-Ph)2 -TTA则表现出双极性电荷传输,空穴迁移率高达0.68 cm 2 V -1 s -1。
Synthetically controlling the optoelectronic properties of dithieno[2,3-d:2′,3′-d′]benzo[1,2-b:4,5-b′]dithiophene-alt-diketopyrrolopyrrole-conjugated polymers for efficient solar cells
We have demonstrated that, by changing the substituent groups on dithieno[2,3-d:2′,3′-d′]benzo[1,2-b:4,5-b′]dithiophene (DTBDT), one could effectively and rationally tune the energy levels, optical band gaps and charge transporting properties, etc. of the DTDBT derivatives (DTBDTs) and their conjugatedpolymers (CPs) and diketopyrrolopyrrole (DPP) derivatives.
我们已经证明,通过改变二噻吩并[2,3- d:2',3'- d ']苯并[1,2- b:4,5- b ']二噻吩(DTBDT)上的取代基,有效,合理地调整DTDBT衍生物(DTBDT)及其共轭聚合物(CP)和二酮吡咯并吡咯(DPP)衍生物的能级,光学带隙和电荷传输性质等。
