    the differences in macrocycle planarity. The extraction experiments of the aforementioned compounds were performed by using metallic picrate salts, and simultaneously for the previously synthesized 17- and 18- membered macrocyclic analogues (m2 and m1). The metal cation extractability was determined for m1, m2, m3 and m4 by UV–Vis spectrophotometry in order to find correlation of structural features

  • Investigation of the one-flask synthesis of porphyrins bearing meso-linked straps of variable length, rigidity, and redox activity

    The reactions of 18 dialdehydes have been examined in the two-step one-flask room temperature porphyrin synthesis. Efficient alkylation methods were established for the reaction of diols and diacids with m-bromomethylbenzaldehyde Dialdehydes linked at the o,o'- or m,m'-positions were converted to strapped porphyrins in yields up to 25%, while the one p,p'-linked dialdehyde that was examined failed to give porphyrin. The resulting porphyrins bear straps joining adjacent meso-positions rather than across the face of the porphyrin. Dialdehydes incorporating rigid groups provided improved yields in some but not all cases. The yield of strapped porphyrin exhibited a maximum at 10(-2) M reactant concentrations. The o,o'-strapped porphyrins exist as atropisomers thai are sufficiently stable to interconversion at room temperature to be separable chromatographically. No atropisomers of m,m'-strapped porphyrins could be separated, though some could be observed by H-1 NMR spectroscopy. For two different m,m'-strapped porphyrins, the Delta G double dagger values for interconversion of the atropisomers were found to be 66 and 68 kJ/mol. The outer rings in these strapped porphyrins range in size from 14 to 24 atoms. Five porphyrins with bridging redox-active groups (ferrocene or anthraquinone) have been prepared in one-flask reactions, including a porphyrin bearing one ferrocene and one anthraquinone in straps across adjacent meta-substituted phenyl sites.

  • Hybrid Orbital Deformation (HOD) Effect and Spectral Red-Shift Property of Nonplanar porphyrin
    作者:Zaichun Zhou、Chenzhong Cao、Qiuhua Liu、Rongqing Jiang

    日期:2010.4.16
    A series of 5,15-meso,meso-strapped nonplanar porphyrins with different degrees of ruffling distortion, as a model system, have been synthesized and characterized. The spectral red-shift of the nonplanar porphyrins was experimentally demonstrated to mainly originate from the hybrid orbital deformation (HOD) effect due to the distortion in the tetrapyrrole macrocycle, which confirmed previous explanations to the red-shift phenomenon.

    A series of copper(II) complexes (1–9 and 3′) derived from bis-dipyrrin ligands (L1–L9 and L3′) with diverse spacer lengths [(CH2)n–] have been described. Structural diversities in these complexes have been explicitly established by spectral and structural studies on these and a closely related nickel(II) complex (3′′). All the ligands and complexes have been thoroughly characterized by spectroscopic

In the complex AgL1ClO4, each silver atom is coordinated by two ligand molecules and one perchlorate anion (T-shaped geometry). The coordination geometry around the silver atom can be described as T-shaped, resulting in a formation
