    Controlled dealkylation by BBr3: efficient synthesis of para-alkoxy-phenols
    摘要:
    Controlled dealkylation of dialkyl-aryl-ethers by substoichiometric BBr3 has been developed as a general tool for the differentiation of the oxygen functions in hydroquinone derivatives. The reaction proceeds smoothly at rt either on linear or branched alkyl-ethers and provides the corresponding p-alkoxy-phenols RO-Ar-OH in high yields. With respect to the conventional alkylation path of Ar(OH)(2), this process represents a tunable and convenient route to key intermediates for conjugated materials with differentiated side chains.

    Mizoroki-Heck偶联聚合作为催化剂转移缩聚反应合成聚对苯撑亚乙烯基的研究
    摘要:
    1,4-双[(2-乙基己基)氧基] -2-碘-5-5-乙烯基苯的咪唑罗基-赫克偶联聚合(1)及其溴代物2与Pd引发剂的合成聚苯撑乙烯撑(PPV)研究了聚合反应是否以链增长聚合反应的方式进行。即使使用5.5当量的Cy 2 NMe(Cy =环己基)作为碱,甚至在室温下也进行了与t Bu 3 PPd(Tolyl)Br(10)的1的聚合,但是PPV的分子量分布宽。2的聚合几乎在相同条件下在室温下进行。在聚合1形成直到末端为H的PPV,末端为I的PPV,直到最后阶段为止,聚合物端基被转化为甲苯基和H。数均分子量(M n)直到大约90%的单体转化率才开始增加,然后急剧增加,这表明常规的逐步增长聚合反应。逐步增长聚合而不是催化剂转移链增长聚合的发生,可以用H-Pd(II)-X(t Bu 3)的低配位能力来解释。P)(X = Br或I),在Mizoroki-Heck偶联反应的催化循环中形成,并与PPV主链的π电子结合;

    Pd initiator were investigated under catalyst‐transfer condensation polymerization conditions for the synthesis of well‐defined poly(p‐phenylenevinylene) (PPV). The Kumada‐Tamao polymerization of vinyl Grignard‐type monomer 1 with Ni(dppp)Cl2 at room temperature did not proceed, whereas aryl Grignard‐type monomer 2 afforded oligomers of low molecular weight.

    A comparative study of conjugated polymers derived from the two 10 pi electron circuits of naphthalene and methano[10]annulene is presented. The annulene pi topology allows for a greater degree of intrapolymer charge delocalization, a key structural parameter for enhancing the performance of organic semiconductors. Molecular design and synthesis based upon unusual aromatic cores will enable facile

  • First hyperpolarizabilities of hexa(ethynyl)benzene derivatives: effect of conjugation length
    作者:Ming Jun Piao、Khalil Chajara、Soo Jung Yoon、Hwan Myung Kim、Seung-Joon Jeon、Tae-Hyun Kim、Kai Song、Inge Asselberghs、Andr? Persoons、Koen Clays、Bong Rae Cho

    A variety of dipolar and octupolar molecules containing CC bonds as the conjugation bridge have been synthesized and the linear and nonlinear optical properties (β) were studied. The β(0) value of the dipole increases with conjugation length, whereas that of the octupole decreases from 2a to 2b with concomitant decrease in λmax. A further increase in the conjugation length to 3a–c increased β(0) because of the larger oscillator strength. Moreover, 3a with the most distorted structure shows the largest β(0), probably because of the dipolar contribution. On the other hand, βyyy/βzzz ratios are smaller than unity, probably because βzzz is overestimated by the errors involved in the resonance correction.
    合成了多种含有CC键作为共轭桥的偶极和八极分子,并研究了其线性和非线性光学性质(β)。偶极子的 β(0) 值随着共轭长度的增加而增加,而八极子的 β(0) 值从 2a 减小到 2b,同时 λmax 减小。由于振荡强度更大,进一步增加 3a-c 的共轭长度会增加 β(0)。此外,结构最扭曲的 3a 显示出最大的 β(0),可能是由于偶极子的贡献。另一方面,βyyy/βzzz 比率小于 1,可能是因为共振校正中涉及的误差高估了 βzzz。
