  Synthesis of pseudoaromatic expanded porphyrin analogues

  摘要：

  Optically active expanded porphyrins bearing thiophene were synthesized by Schiff base forming reaction. The condensation of thiophene containing 1,14-bisformyl tripyrrane with aromatic diamines Failed to give desired macrocycles but condensation with aliphatic 1,2-diamines gave the desired products. The macrocycles synthesized tend to maintain 18 pi system and the ethylene bridge shows somewhat resistance toward oxidation. (C) 1999 Elsevier Science Ltd. All rights reserved.

  The synthesis of a new class of carbazole based macrocycles via [3 + 1] acid-catalyzed condensation is reported. Spectroscopic investigations and computational studies imply that these macrocycles have a large influence on the electronic structure in comparison to previously reported carbazole based macrocycles. Macrocycle 8 bearing a furan ring reversibly binds aqueous Hg2+ with high affinity over

  synthesis of core‐modified meso aryl hexaphyrins with an internal thiophene bridge is reported. Introduction of the thiophene bridge alters the electronic structure as well as the π‐electron circuit, resulting in increases in singlet lifetime (τs) and the two‐photon absorption (TPA) cross‐section. Furthermore, for the sulfur derivative, the internal bridging thiophene participates in a π‐electron conjugation

  macrocycles containing benzenoid rings rarely show global aromaticity/antiaromaticity. Herein, we report an annulene-like macrocycle CBTT and its S,S-dioxidized macrocycle DOCBTT with alternative quinoidal thiophene/1,1-dioxide thiophene and triphenyl amine moieties. They both showed temperature-dependent intramolecular dynamics and global antiaromatic character with 32π electrons at low temperature. However

  Acid-catalyzed condensation of a newly prepared di-m-benzipentapyrrane with appropriate mono- and diheterocyclic dialcohols selectively produced stable di-m-benzihexaphyrins and di-m-benziheptaphyrins with only two meso-carbon bridges. Single-crystal X-ray diffraction analyses reveal planar conformation with slight distortion of bridged phenylene rings. Despite the presence of m-phenylene units interrupting the global delocalization, the presence of bithiophene units in di-m-benziheptaphyrins 3a-b exhibits altered optical features covering the entire visible region (ca. 250-720 nm), exhibiting a black dye property as a "metal-free" porphyrinoid.
