Fused Hybrids of a [22]Smaragdyrin BF₂ Complex with a Ni^II Porphyrin

Abstract

22]Smaragdyrin BF 2 complex (S)-Ni II porphyrin (P) fused hybrids were synthesized through Suzuki-Miyaura coupling of brominated S with borylated P and subsequent oxidative fusion reaction with FeCl 3 as the first example of directly fused porphyrinoids bearing cycloheptatriene linkage. These fused hybrids have been fully characterized, including their Xray structural analysis. Owing to the cycloheptatriene linkage, these fused hybrids adopt waving structures. These fused hybrids display red-shifted and enhanced Q-like bands and characteristic redox potentials, depending upon the constitution and the linking position.

Mono- and bis-Pd(ii) complexes of N-confused dithiahexaphyrin(1.1.1.1.1.0) with the absorption and aromaticity modulated by Pd(ii) coordination, macrocycle contraction and ancillary ligands

“…For example, hexaphyrins may coordinate to either one or two metal ions within the two cavities, and the coordinated metal ions exhibit rich oxidation states. 31–48 In addition, the N-confused pyrrole unit may trigger interesting macrocycle transformations and thus further modulate the coordination behavior. 49–55 These metal complexes are promising for applications in various areas like catalytic, photoelectric and biomedical materials.…”
