A carbazole-containing porphyrinoid: synthesis and oxidation to the porphyrin-state.
نویسندگان
چکیده
Carbazole-containing porphyrinoid was synthesised for the first time via Suzuki-Miyaura cross-coupling reaction. Oxidation with MnO(2) yielded its porphyrin-state featuring macrocyclic aromaticity in exchange for the loss of the resonance energies of the benzene rings.

A new carbazole- containing polymer has been synthesized for further photophysical studies. Efficient synthesis of the substituted methyl methacrylate has been accomplished via microwave assisted synthesis of 1 - chloro - 4-carboxy -5,6, 7, 8- tetrahydrocarbazole followed by further steps, such as reduction of the 4-substituted methyl carboxylate, dechlor...
متن کاملDendrimers made of porphyrin cores and carbazole chromophores as peripheral units. Absorption spectra, luminescence properties, and oxidation behavior.
Luminescent and redox-active porphyrin-based dendrimers of first and second generation have been synthesized, and their absorption spectra, photophysical properties, and oxidation behavior have been investigated, together with those of the corresponding aldehyde carbazole precursors. All the dendrimers contain a porphyrin core and carbazole-based chromophores as branches. The structural formula...

متن کاملA porphyrin-related macrocycle from carbazole and pyridine building blocks: synthesis and metal coordination.
In this communication, we report the synthesis of a novel porphyrin-related macrocycle. The core modifications result in aromatic building blocks connected exclusively via aryl-aryl bonds. The concept of synthesis permits the formation of a cavity similar to that of a porphyrin combined with the ability to bind metal ions to provide neutral metal complexes.
