  Synthesis and characterization of a new 26.pi.-aromatic thiophene-containing macrocyclic ligand

  摘要：

  A new porphyrin-like or ''pentaplanar'' macrocyclic ligand (9) has been synthesized by a McMurray coupling of 2,5-bis(5-formyl-4-propyl-2-pyrrolyl)thiophene, followed by air oxidation in chloroform. This highly stable macrocycle is aromatic, as evidenced by its UV-visible and H-1 NMR spectra. The pathway to 9 as well as the synthesis of two asymmetric dipyrrolylthiophenes is also described.

  time as its alkyl analogue from ethyl 4-propyl-1H-pyrrole-2-carboxylate. The substituent effect was found to be more intense than reported positional isomeric tetrapropylporphycenes. The freebase porphycene exhibited moderate fluorescence and complexation ability with divalent metal ions, including Zn(II), which displayed an enhanced emission quantum yield (∼30%). The Pd(II) complex and freebase β-tetrabromoporphycene

  我们首次以4-丙基-1 H-吡咯-2-甲酸乙酯为原料设计合成了3,6,13,16-四丙基卟啉作为其烷基类似物。发现取代基效应比报道的位置异构四丙基卟啉更强烈。游离碱卟啉表现出中等的荧光和与包括 Zn(II) 在内的二价金属离子的络合能力，表现出增强的发射量子产率 (~30%)。Pd(II) 配合物和游离碱 β-四溴卟啉有效地产生单线态氧（分别为 75% 和 51%），因此可能会在光动力治疗中作为潜在的光敏剂应用。

  vinylpyrrole, was prepared from a formylpyrrole derivative, Meldrum's acid, and 1,3-dimethylbarbituric acid. The optical properties of the chromophore both in the solution and solid states were investigated by UV-vis and fluorescence spectroscopy. Single crystal X-ray diffraction measurements revealed that the dimethylbarbituric acid adduct formed a J-aggregate in the solid and resulted in higher fluorescence

  由甲酰基吡咯衍生物、Meldrum 酸和 1,3-二甲基巴比妥酸制备聚集诱导的发射发色团乙烯基吡咯。通过紫外-可见光谱和荧光光谱研究了溶液和固态生色团的光学性质。单晶 X 射线衍射测量表明，与 Meldrum 的酸加合物相比，二甲基巴比妥酸加合物在固体中形成 J-聚集体并产生更高的荧光量子产率。发现发射增强是通过限制固态中的分子旋转而发生的。
