A leaving substituent-containing compound represented by General Formula (I), wherein the leaving substituent-containing compound can be converted to a compound represented by General Formula (Ia) and a compound represented by General Formula (II), by applying energy to the leaving substituent-containing compound, in General Formulas (I), (Ia) and (II), X and Y each represent a hydrogen atom or a leaving substituent, where one of X and Y is the leaving substituent and the other is the hydrogen atom; Q2 to Q5 each represent a hydrogen atom, a halogen atom or a monovalent organic group; Q1 and Q6 each represent a hydrogen atom or a monovalent organic group other than the leaving substituent; and among the monovalent organic groups represented by Q1 to Q6, adjacent monovalent organic groups may be linked together to form a ring.

hexathiaheptacenes show liquid crystalline properties dependent on their alkyl chain length. As observed from differential scanning calorimetry and polarized optical microscopy compared with DTTBDT a and b, DTTBDT c and d exhibit thermotropic liquid crystalline textures due to the rigid conjugated skeleton and the flexible long alkyl chains. For all four derivatives, the structural analysis indicates the formation
通过以下方法合成了具有各种烷基基团的可溶液加工的六硫杂庚并二噻吩并噻吩并[2,3- d ; 2',3'- d ']苯并[1,2- b:4,5- b ']二噻吩(DTTBDT a–d)。三氟甲磺酸引起的闭环。紫外/可见吸收,光致发光光谱和循环伏安法与密度泛函理论量子化学计算相结合,以确定DTTBDT a–d的光物理和电化学性质。另外,新的六硫杂庚烯显示出取决于它们的烷基链长的液晶性质。从差示扫描量热法和偏振光学显微镜观察,与DTTBDT a和b,DTTBDT c和d由于刚性共轭骨架和柔性长烷基链而呈现出热致液晶质地。对于所有四个衍生物,结构分析表明形成了层状结构,其中令人吃惊的是,分子的包装较差。该分子无序是p型场效应晶体管性能低下的主要原因。
High-Performance Solar Cells using a Solution-Processed Small Molecule Containing Benzodithiophene Unit
A conjugated smallmoleculecontaining a benzodithiopheneunit shows high performance in bulk heterojunction (BHJ) solarcells. Using the simple solution spinning process, a high PCE is achieved by employing this molecule as the donor in BHJ solarcells.
A new ladder-type benzodi(cyclopentadithiophene)-based donor–acceptor polymer and a modified hole-collecting PEDOT:PSS layer to achieve tandem solar cells with an open-circuit voltage of 1.62 V
We have developed a new ladder-type conjugated polymer PBDCPDTâFBT and a robust interconnecting layer (ICL) integrating a hole-collecting m-PEDOT:PSS layer with an electron-collecting ZnO layer. The inverted device using PBDCPDTâFBT exhibited a high power conversion efficiency (PCE) of 5.76% with a Voc of 0.81 V, a Jsc of 12.82 mA cmâ2, and a FF of 55.5%. The inverted tandem device incorporating the PBDCPDTâFBT and ICL achieves a Voc of 1.62 V leading to a PCE of 7.08%.
