WebAug 4, 2024 · Carbodiphosphoranes (CDPs) are carbon (0) compounds with two PR 3 ligands. These compounds feature P→C donor–acceptor interactions, and as a result, the carbon atom retains two lone pairs of electrons. This type of compound is called a carbone.

WebApr 16, 2024 · Sapphyrins (Pentaphyrin(1.1.1.1.0)s) are the first expanded porphyrins to have been discovered by Woodward et al. [1]. β-Substituted sapphyrins are often used as versatile anion-binding agents and their structures have been analyzed in their protonated forms. Consequently, meso-substituted sapphyrins are sometimes insufficiently … WebZinc(II) complexes of meso-to-meso 2,2’-bithiophene-bridged cyclic porphyrin arrays are suitable for multicharge storage and hence are of interest as molecular information storage systems. Covalently linked, cyclic porphyrin arrays have been explored mainly as artificial photosynthetic antennae and large host molecules. In such arrays, a variety of bridges …
