  • Electron transfer in bis-porphyrin donor-acceptor compounds with polyphenylene spacers shows a weak distance dependence
    作者:Anna Helms、David Heiler、George McLendon
    DOI:10.1021/ja00041a047
    日期:1992.7
    containing one, two, or three phenyl bridges. Complete synthetic details are provided. For studies of photochemical electron transfer, mixed metals were incorporated, with zinc in one porphyrin macrocycle and Fe III (bis-imidazole) in the other macrocycle. When photoexcited, an electron is transferred from Zn to Fe III
    已经合成了一系列亚苯基桥连的双卟啉加合物,包含一个、两个或三个苯桥。提供了完整的合成细节。为了研究光化学电子转移,加入了混合金属,锌在一个卟啉大环中,而 Fe III(双咪唑)在另一个大环中。当光激发时,一个电子从 Zn 转移到 Fe III
  • Stacked Porphyrin Arrays from Hydrogen-Bonded Porphyrin–Resorcinol 1D Chains
    作者:Toshihiro Tanaka、Ken Endo、Yasuhiro Aoyama
    DOI:10.1246/bcsj.74.907
    日期:2001.5
    The Ni(II) complex of monoresorcinol derivative of a sterically unhindered tetraalkylporphyrin (3) affords adducts 3•(methanol) and 3•1.5(acetophenone). In the crystals, porphyrin 3 forms hydrogen-bonded (O–H···O–H) polyresorcinol chains with the porphyrin residues sticking out of the chains. The chains are self-assembled in such a manner as to give closely stacked interchain porphyrin columns, while the guest molecules are either firmly bound to the hydrogen-bonding sites (in the case of methanol) or incorporated in the channels running in parallel with the porphyrin stacks (in the case of acetophenone). The formation of such a stacked porphyrin array is not observed when the guest is changed to 4-heptanone or when the porphyrin is changed to a sterically hindered one 4 or 5 with full substitution at the meso- or the β-positions. The mode of interchain porphyrin stacking is discussed in light of the crystal structures of adducts 3•(4-heptanone), 4•pyridine, and 5•(2-nonanone).
    空间阻碍小的四烷基卟啉(3)的单间苯二酚衍生物的Ni(II)配合物生成加合物3·(甲醇)和3·1.5(苯乙酮)。在晶体中,卟啉3通过氢键(O-H…O-H)与卟啉残基形成多间苯二酚链,这些残基突出于链外。这些链自我组装,形成紧密堆积的卟啉柱,同时客体分子要么紧缚于氢键位点(甲醇的情况下),要么内嵌于与卟啉堆平行延伸的通道中(苯乙酮的情况下)。当客体变为庚-4-酮或卟啉变为在次甲基或β位完全取代的空间阻碍大的4或5时,未观察到这种堆积的卟啉阵列的形成。基于加合物3·(4-庚酮)、4·吡啶和5·(2-壬酮)的晶体结构,讨论了卟啉间堆积的模式。
  • Dicarbaporphyrinoid Systems. Synthesis of Oxo-<i>adj</i>-dibenziphlorins

    A series of diformylbenzophenones were generated by sequentially reacting protected bromobenzaldehydes with n-butyllithium and ethyl N,N-dimethylcarbamate. The acetal protective groups were cleaved with refluxing formic acid. Vilsmeier–Haack formylation of 2,2′,4,4′-tetramethoxybenzophenone also afforded a related dialdehyde.

    通过使受保护的溴苯甲醛与正丁基锂和N,N-二甲基氨基甲酸乙酯顺序反应,生成了一系列二甲酰基二苯甲酮。缩醛保护基被回流的甲酸裂解。2,2',4,4'-四甲氧基二苯甲酮的Vilsmeier-Haack甲酰化反应也提供了相关的二醛。三种二苯甲酮二醛与二吡咯基甲烷的麦克唐纳“ 2 + 2”缩合反应产生了由两个苯和两个吡咯环构成的氧卟啉类似物。游离碱恶二苯并hl庚因在溶液中相当不稳定,并且在大多数情况下,这些卟啉类化合物作为相应的三氟乙酸盐被分离出来。6-氧代邻苯二甲酸酯的光谱性质-dibenziphlorins与非芳族环系统一致。DFT计算表明,大环与平面度大不相同,特别是当芳烃环上存在甲氧基取代基时。

The proton NMR spectrum also showed a significantly reduced diamagnetic ring current where the meso-protons gave resonances near 9.3 ppm instead of typical porphyrin values of 10 ppm.

    从2-茚满酮开始已经合成了与茚稠合的卟啉。丙酸中的苄基或叔丁基乙酰乙酸酯肟与2-茚满酮和锌粉的克诺尔型反应,可得到良好的茚并吡咯产率。用N治疗然后,-氯代琥珀酰亚胺产生8-氯代衍生物,并使它们与5-未取代的吡咯反应,得到结合有稠合的茚单元的二吡咯。苄基酯保护基的氢解作用提供了相关的二羧酸,但在MacDonald“ 2 + 2”反应条件下与二吡咯甲烷二醛缩合生成的目标茚并卟啉收率很低。但是,当将与茚基稠合的双吡咯与TFA-原甲酸三甲酯转化为相应的二醛,然后与双吡咯甲烷二羧酸反应时,分离出茚并卟啉的产率为26%。卟啉给出了高度修饰的UV-vis吸收光谱,在Soret区域显示了三个强带,并延伸了超过700 nm的一系列Q带。中质子产生的共振接近9.3 ppm,而不是典型的卟啉值10 ppm。还制备了镍(II),铜(II)和锌络合物,它们显示出不寻常的紫外可见吸收光谱,并具有红移的索雷特和Q吸收红

    Rate constants for hydrogen-atom transfer (HAT) from bilirubin dimethyl ester (BRDE) and biliverdin dimethyl ester (BVDE) to peroxyl radicals during inhibited autoxidation of styrene initiated by azo-bisisobutyronitrile (AIBN) were kinh(BRDE) = 22.5 × 104 and kinh(BVDE) = 10.2 × 104 M-1 s-1, and the stoichiometric factors (n) were 2.0 and 2.7, respectively.
