Synthesis of Binuclear Copper (II) Complexes with Expanded Porphyrins
The synthesis and characterization of some new binuclear copper (II) complexes, based on the use of large, pyrole-containing macrocycles, the so called "expanded porphyrins", [Cu2(macrocycle)]+4 is described. Electron Spin Resonance (ESR) studies indicate a weak "half-field line", which is characteristic of the Cu(II)-Cu(II) dimer, is observed at about 1600G. The obser...
متن کامل(Metallo)porphyrins for potential materials science applications
The bottom-up approach to replace existing devices by molecular-based systems is a subject that attracts permanently increasing interest. Molecular-based devices offer not only to miniaturize the device further, but also to benefit from advanced functionalities of deposited molecules. Furthermore, the molecules itself can be tailored to allow via their self-assembly the potential fabrication of...
متن کاملInteractions between expanded porphyrins and nucleic acids
Two types of interaction of expanded porphyrins and nucleic acids are discussed. The first involves the specific chelation of the anionic phosphate diester backbone of DNA by the monoprotonated form of the water soluble sapphyrin 2. Support for the proposed binding mode derives from a variety of spectroscopic and biochemical studies, including visible absorption spectroscopy, circular dichroism...
متن کاملFused core-modified meso-aryl expanded porphyrins.
The synthesis and characterization of the first examples of singly and doubly fused expanded porphyrins containing dithienothiophene (DTT) cores are reported.
متن کاملTransition-metal complexes of expanded porphyrins.
Over the last 2 decades, the rapid development of new synthetic routes for the preparation of expanded porphyrin macrocycles has allowed for the exploration of a new frontier consisting of "porphyrin-like" coordination chemistry. In this Account, we summarize our exploratory forays into the still relatively poorly explored area of oligopyrrolic macrocycle metalation chemistry. Specifically, we ...
