Singly and doubly β-to-β platinum-bridged porphyrin dimers and their reductive eliminations
نویسندگان
چکیده
2-Borylated porphyrins reacted with Pt(cod)Cl2 to give b-to-b platinum-bridged porphyrin dimers, which were converted to b-to-b directly linked porphyrin dimers through triphenylphosphine-mediated reductive elimination. Similar reactions of 2,18-diborylated Ni(II)–porphyrin and Zn(II)–porphyrin gave the corresponding doubly b-to-b platinum-bridged porphyrin dimers. Treatment of the doubly b-to-b platinum-bridged Ni(II)–porphyrin dimer with triphenylphosphine caused a single reductive elimination to produce a Ni(II)–porphyrin dimer possessing a b-to-b platinum bridge and a b-to-b direct C–C bond.

Excess polarizability reveals exciton localization/delocalization controlled by linking positions on porphyrin rings in butadiyne-bridged porphyrin dimers.
We report direct measurements of the excess polarizability volumes of butadiyne-bridged zinc porphyrin dimers at singly beta-to-beta (1Zn) and doubly beta-to-beta (2Zn) positions using the transient dc photoconductivity (TDCP) technique. The excess polarizability volumes of the singlet exciton for 1Zn and 2Zn are 110 and 270 A(3), respectively, while those of the triplet exciton are approximate...
متن کاملSynthesis of directly fused porphyrin dimers through Fe(OTf)3-mediated oxidative coupling.
An efficient and general Fe(OTf)3-mediated oxidative coupling method was developed for the synthesis of doubly or triply linked porphyrin dimers. Besides the central metal and peripheral substituent, regioselectivity of the oxidative coupling was found to be closely relevant to the onset oxidation potential of the porphyrin substrate, and the reactant with higher E(onset(ox)) tends to generate ...
متن کاملOn the Influence of the Bridge on Triplet State Delocalization in Linear Porphyrin Oligomers
The extent of triplet state delocalization is investigated in rigid linear zinc porphyrin oligomers as a function of interporphyrin bonding characteristics, specifically in meso-meso singly linked and β,meso,β fused structures, using electron paramagnetic resonance techniques. The results are compared with those of earlier measurements on porphyrin oligomers with alkyne linkers exhibiting diffe...
متن کاملHighly planar diarylamine-fused porphyrins and their remarkably stable radical cations.
Oxidative fusion reactions of meso-phenoxazino Ni(ii) porphyrin were found to be temperature dependent, giving rise to either a doubly phenylene-fused product at room temperature or a singly phenoxazine-fused product at 70 °C. The latter was further oxidized to a doubly phenoxazine-fused Ni(ii) porphyrin, which was subsequently converted to the corresponding free base porphyrin and Zn(ii) porph...
متن کاملSynthesis and Photophysical Properties of Two Diazaporphyrin-Porphyrin Hetero Dimers in Polar and Nonpolar Solutions.
Two diazaporphyrin (DAP)-porphyrin hetero dimers, in β-meso and β-β configurations, were prepared to study their photoinduced intramolecular electron transfer properties. The two meso nitrogen atoms in the porphyrin ring of DAP change its redox potential, making DAP more easily reduced, compared to its porphyrin counterpart. A charge-transfer from porphyrin to DAP in both hetero dimers was veri...
