设计并合成了一系列带有N,N-二芳基氨基取代基作为封端基团的新的不对称方酸衍生物,即ASQAr-1-6。与参考化合物相比ASQB轴承Ñ,Ñ -diisobutylamino封端剂中,所有的六个目标化合物表现出改进的热稳定性,红移和扩大吸收带以及较低的HOMO和LUMO能级。尽管大多数化合物的空穴迁移率仍低于ASQB,但是使用ASQAr-1-6固溶处理的异质结小分子有机太阳能电池(BHJ-SMOSC)作为电子供体材料,它们的功率转换效率(PCE,3.08–3.69%)都大大高于基于ASQB的参考器件(PCE = 1.54%)。基于ASQAr-1-6的BHJ -SMOSC的光伏性能大大提高,可以归因于同时提高的开路电压(V oc,0.81-0.87 V vs. 0.75 V),短路电流密度(J sc,8.07–9.06 mA cm -2 与5.40 mA cm -2)和填充因子(FF,0.45-0

The present invention relates to nucleoside diphosphate mimics and nucleoside triphosphate mimics, which contain diphosphate or triphosphate moiety mimics and optionally sugar-modifications and/or base-modifications. The nucleotide mimics of the present invention, in a form of a pharmaceutically acceptable salt, a pharmaceutically acceptable prodrug, or a pharmaceutical formulation, are useful as antiviral, antimicrobial, and anticancer agents. The present invention provides a method for the treatment of viral infections, microbial infections, and proliferative disorders. The present invention also relates to pharmaceutical compositions comprising the compounds of the present invention optionally in combination with other pharmaceutically active agents.
N,N-Diarylamino end-capping as a new strategy for simultaneously enhancing open-circuit voltage, short-circuit current density and fill factor in small molecule organic solar cells
bulk-heterojunction small moleculeorganicsolarcells (BHJ-SMOSCs) using ASQAr-1–6 as electron donor materials all show drastically higher power conversion efficiency (PCE, 3.08–3.69%) than that of the ASQB-based reference device (PCE = 1.54%). The much enhanced photovoltaic performance of BHJ-SMOSCs based-on ASQAr-1–6 could be attributed to the simultaneously enhanced open-circuitvoltage (Voc, 0.81–0.87 V
