(chloro)iron(III), iron(II), cobalt (II), and zinc(II) complexes is reported. These complexes serve as models for the active site of the oxygen binding haemoproteins. In addition to reversible binding of dioxygen by each of the iron (II) porphyrin complexes, the 1-methyl-imidazole-(“C3-capped porphyrin”) iron (II) complex (23) reacts reversibly with carbon monoxide, in solution at 25°C.

The synthesis of 13 novel meso-glycosylarylporphyrins where the carbohydrate moiety is separated from the aryl substituent by a spacer arm is described. These compounds were synthesized by different methods, either by direct glycosylation of the ortho- or para-hydroxyalkoxyarylporphyrin or by condensation of glycosylated aldehyde with pyrrole or meso-(p-tolyl)dipyrromethane. In all cases, a β configuration

The synthesis of a porphyrin–fullerenedyad with “parachute” topology is reported. To determine whether the dyad is “flexing” at room temperature, low‐temperature NMR experiments were used. Computational modeling has shown the low‐energy conformation of the dyad to be nonsymmetric. Although, 1H NMR spectroscopy at room temperature is consistent with a molecule with C2v symmetry, the spectrum changes
报道了具有“降落伞”拓扑结构的卟啉-富勒烯二联体的合成。为了确定二元体在室温下是否“弯曲”,使用了低温NMR实验。计算模型表明,二分体的低能构象是不对称的。尽管室温下的1 H NMR光谱与具有C 2 v对称性的分子是一致的,但随着“挡风玻璃刮水器”状运动的降低,光谱随着温度的降低而发生变化,其中卟啉部分从C 60的一侧旋转球形到另一个。纳秒和皮秒的荧光寿命实验表明,两种成分均会导致荧光衰减,并且与一种以上的构象异构体一致。

Molecular modeling studies reveal that the lowest energy conformation of the dyad is not the C(2)(v)() symmetrical structure, but rather one in which the porphyrin moves over to the side of the fullerene sphere, bringing the two pi-systems into close proximity, which enhances van der Waals attractive forces. To account for the NMR data, it is proposed that the dyad is conformationally mobile at room temperature
A novel covalently linked C60âporphyrin dyad has been prepared by cyclopropanation of C60 with a strapped porphyrin malonate; its fluorescence spectrum shows strong quenching of the porphyrin singlet excited state by the attached C60.
