  • Improved synthesis dimethylhomoecoerdianthrone (HOCD) and its functionalization through facile amination reactions

    An improved synthesis of dimethylhomoecoerdianthrone (HOCD), a dye used for singlet oxygen detection, was reported by isolation of a key intermediate followed by cyclization reaction. Moreover, dehydrogenative amination reaction between HOCD and alkyl amines and diamines resulted in amine functionalized HOCD derivatives with good yield. The observed reactivity depends on the nucleophilicity of amine
    据报道,通过分离关键中间体并进行环化反应,可以改进合成二甲基高二蒽酮(HOCD)(一种用于单线态氧检测的染料)的方法。此外,HOCD与烷基胺和二胺之间的脱氢胺化反应以良好的收率得到了胺官能化的HOCD衍生物。观察到的反应性取决于胺的亲核性和HOCD的亲电子性。DFT计算表明该反应涉及1,4-迈克尔加成,随后由于芳构化而使氢原子迁移。在充气条件下,发生脱氢反应以还原酮结构。该CN偶联反应可用于构建具有近红外光子性质的分子材料。最后,我们说明了HOCD派生出HOCD-SO 3-可以接枝到半导体纳米晶体(量子点)上,以提供用于高选择性检测单线态氧的开启荧光纳米探针。

  • Subpicosecond transient absorption studies of the photocycloreversion of an aromatic endoperoxide

  • Rate parameters for the two-step photofragmentation of aromatic endoperoxides in solution
    作者:K. Jesse、F. J. Comes
    DOI:10.1021/j100156a051
    日期:1991.2
    The formation of dimethylhomoocoerdianthrone (HOCD) following subpicosecond laser photolysis of its endoperoxide (PO) was studied by laser-induced fluorescence (LIF) in the solvents dichloromethane and toluene. The measured rise time of the LIf signal refers to a time constant of tau-2 = 1.7 +/- 0.5 ps at 22-degrees-C. The study of the characteristic rate constant at different temperatures gives an activation energy of E(a) = 5.5 +/-0.5 kcal/mol and a preexponential factor of A = 10(15.7 +/- 0.3) s-1 in toluene. These parameters are consistent with our earlier model for the two-step photofragmentation of aromatic endoperoxides, which assumes a short-lived 1.6-biradical intermediate crossing an activation barrier. The photolysis study of the newly synthesized endoperoxide of anthrabisbenzothiopyran (ABTPO) reveals that photocycloreversion starting from S3(pi-pi*) proceeds with a time constant of tau-2 = 46 +/- 6 ps in dichloromethane (at 22-degrees-C). In this case the activation parameters amount to E(a) = 5.0 +/- 0.6 kcal/mol and A = 10(14.8 +/- 0.3) s-1. The observed activation barrier on the potential energy surface can be a result from resonance effects in the chromophores of the peroxy biradical. The large A factors reflect the importance of internal degrees of freedom in the transition state.
