The various inventions and/or their embodiments disclosed herein relate to certain naphthalene diimide (NDI) compounds wherein the NDI groups are bonded to certain subclasses of bridging heteroaryl (hAr) groups, such as the "NDI-hAr-NDI" oligomeric compounds, wherein hAr is a heteroaryl group chosen to provide desirable electronic and steric properties, and the possible identities of the "Rz" terminal peripheral substituent groups are described herein. Transistor and inverter devices can be prepared.
The present invention relates to compounds that are electron-deficient acceptors, donor- acceptor polymers that are synthesized from such electron-deficient acceptors, semiconductor devices synthesized from such donor-acceptor polymers and methods of synthesis of such electron-deficient acceptors, donor-acceptor polymers and semiconductor devices.

Two donor–acceptor polymer semiconductors based on highly electron-deficient pyrrolo[3,4-d]pyridazine-5,7-dione unit were synthesized by Stille cross-coupling polymerization, and their thermal property, photophysical property, electrochemical property, microstructure, application as organic thin-film transistors, and photovoltaic property were investigated. Because of the strong electron-accepting
通过Stille交叉偶联聚合反应,合成了两种基于高度缺电子的吡咯并[3,4- d ]哒嗪-5,7-二酮单元的供体-受体聚合物半导体,它们的热性质,光物理性质,电化学性质,微观结构,研究了其作为有机薄膜晶体管的应用以及光伏性能。由于吡咯并[3,4- d ]哒嗪-5,7-二酮具有很强的电子接受特性,新聚合物(P1和P2)显示出更宽的吸收,更小的带隙(1.70对1.98 eV)和更深的LUMO比邻苯二甲酰亚胺基聚合物PBDT-PhBT的水平(−3.60 vs -3.37 eV)(图1)。所制造的有机薄膜晶体管器件表现出空穴传输行为,并且获得最高迁移率1.14×10 -3 cm 2 V -1 s -1。基于两种聚合物作为电子给体和PC 71 BM作为电子受体的体-异质结太阳能电池表现出高的开路电压,并且聚合物P1和P2的功率转换效率分别为2.71%和3.66%。

non-fullerene acceptors in organic photovoltaics also entails a change in the requirements to the polymer donor in terms of optical and morphological properties leading to a demand for novelconjugated polymers. Herein, we report on the synthesis of a 1,4-bis-(thiophene-2-yl)-pyrrolopyridazinedione basedcopolymer with 2-ethylhexyl substituents on the pyrrolopyridazinedione moiety. A 2D conjugated benzodithiophene
非富勒烯受体在有机光伏中的最新成功还导致对聚合物供体的光学和形态学性质的要求发生变化,从而导致对新型共轭聚合物的需求。在此,我们报道了在吡咯并哒嗪二酮部分具有2-乙基己基取代基的1,4-双-(噻吩-2-基)-吡咯并哒嗪二酮基共聚物的合成。选择2D共轭苯并二噻吩(BDT)作为共聚单体。所得共聚物T-EHPPD-T-EHBDT的分子量为10.2kDa,光学带隙为1.79eV,空穴迁移率为1.8×10 -4 cm 2 V -1 s -1以及相对于基材的优选的面朝上取向。相对较宽的带隙以及确定的能级(HOMO:-5.47 eV,LUMO:-3.68 eV)与窄带隙非富勒烯受体ITIC-F匹配,后者被用作主体中的受体相研究的太阳能电池中的异质结吸收层。在吸收层中使用1:1的施主:受主比率,以倒置结构制备的太阳能电池显示出高达7.4%的功率转换效率。
Dimesitylboryl-ended oligothiophene with tetrazine as core: Synthesis, structure and Diels–Alder reactivity
A dimesitylboryl-ended oligothiophene with tetrazine as core (BTz) was synthesized and its reactivity and spectral changes toward trans-cyclooctene ((4E)-TCO-OH), cis-cyclooctene and bicyclo[6.1.0]non-4-yn-9-ylmethanol were comprehensively studied. The fluorescence intensity of BTz was enhanced up to more than 100 times upon bioorthogonal reaction with (4E)-TCO-OH. In addition, the first crystal structure
