合成了四种以菲和萘为基础的供体-受体(DA)型共轭聚合物(PA1,PA2,PA3和PA4),作为有机场效应晶体管(OFET)和本体异质结有机物的供体光伏(OPV)。取决于供体-多芳族(PA)化合物,二甲氧基取代基对光学,电化学,电荷传输和光伏性质具有重要影响。这些PA基共聚物从最小到最大的光学带隙如下:1.52 eV(1,5-二甲氧基取代的萘(PA4)),1.59 eV(未取代的萘(PA3)和1.63 eV(未取代的菲(PA1),和取代的9,10-二甲氧基菲(PA2))。尽管该值随化合物而变化,但是由于二甲氧基取代基的给电子性质,发现PA2和PA4均具有比PA1和PA3更高的最高占据分子轨道(HOMO)能级。没有二甲氧基取代基的PA基共聚物显示出高度平衡的双极性行为,约为1 cm 2 V -1 s -1,而二甲氧基改性PA(MeOPA)基共聚物的电子迁移率受到抑制。反向本体异质结OPV基于

We report the regiocontrolled syntheses of ethene‐bridged para‐phenylene oligomers in three distinct classes by using PtII‐ and RuII‐catalyzed aromatization. This synthetic approach has been developed based on twofold aromatization of the 1‐aryl‐2‐alkynylbenzene functionality, which proceeds by distinct regioselectivity for platinum and ruthenium catalysts. Variable‐temperature NMR spectra provide
Alkoxy highly edge-decorated polycylic aromatic hydrocarbons (PAHs) have been formed. Oxidative cross coupling of phenols constructs frameworks without any need for the prefunctionalization required by conventional methods. Moreover, smaller optical gaps can be achieved relative to systems of similar size.
Iridium-catalyzed borylation of phenacenes with bis(pinacolato)diboron proceeds either in an edge-selective manner for diborylation or an edge/side-selective manner for tetraborylation. Multiply borylated [n]phenacenes (n = 3-5) were synthesized in reasonable yields. (C) 2011 Elsevier Ltd. All rights reserved.
