Pentafluorophenyl dipyrrin as probe for transition metal ion detection and bioremediation in: Bacillus subtilis and Bacillus cereus
Prasannan, Dijo,Arunkumar, Chellaiah
, p. 11190 - 11200 (2017)
We report a highly sensitive and selective "turn-on" fluorescent/colorimetric probe, 5-(pentafluorophenyl)dipyrrin (1), for selected transition metal ions in aqueous medium at biological pH. The limit of detection for Zn(ii), Hg(ii), Cu(ii) and Ni(ii) is
Oxygen reduction catalyzed by a fluorinated tetraphenylporphyrin free base at Liquid/Liquid interfaces
Hatay, Imren,Su, Bin,Mendez, Manuel A.,Corminboeuf, Clemence,Khoury, Tony,Gros, Claude P.,Bourdillon, Melanie,Meyer, Michel,Barbe, Jean-Michel,Ersoz, Mustafa,Zalis, Stanislav,Samec, Zdenek,Girault, Hubert H.

The diprotonated form of a fluorinated free base porphyrin, namely 5-(p-aminophenyl)-10,15,20-tris(pentafluorophenyl)porphyrin (H2FAP), can catalyze the reduction of oxygen by a weak electron donor, namely ferrocene (Fc). At a water/1,2-dichlor
Mono-and di-(2,3,5,6-tetrafluoro-4-N, N-dimethylaminophenyl) meso-tetraarylporphyrins: Synthesis, spectral, structural and electrochemical studies
Ramesh, Jagadeesan,Arunkumar, Chellaiah
, p. 359 - 370 (2018)
A new series of mono-/di-aminated meso-tetraarylporphyrins has been synthesized and characterized by conventional spectroscopic methods. Crystal structure analysis shows that interactions involving halogens are the major contributors, and the relative con

The investigation presented in this paper deals with new free-base corroles substituted with different peripheral groups. These aromatic macrocycles were efficiently synthesized by a [2+1] approach from dipyrromethanes. Moreover, the basic spectroscopic studies of the dyes in chloroform were conducted, and the UV-Vis absorption, fluorescence and ESR parameters were estimated. The experimental data were supported by quantum chemical calculations. The presence of monomeric dye structures is concentration independent (10-6-10-4 M), as expected for dyes in a solvent of low polarity, and rules out aggregate formation of corroles dissolved in chloroform. The excitation emission and fluorescence life-time values confirm the monomeric structure of the corroles. The spectra were compared with the time-dependent density functional theory (TD-DFT) results for the HOMO-LUMO states. The ESR examinations strongly show that for any type of studied fluorine corrole an unpaired electron is localized on the corrole macroring but not on the substituents both before and after light illumination. Laser illumination creates additional radicals, however with different effectiveness depending on the sample.
Design and synthesis of benzimidazole phenol-porphyrin dyads for the study of bioinspired photoinduced proton-coupled electron transfer
Mora, S. Jimena,Heredia, Daniel A.,Odella, Emmanuel,Vrudhula, Uma,Gust, Devens,Moore, Thomas A.,Moore, Ana L.
, p. 1336 - 1345 (2019)
Benzimidazole phenol-porphyrin dyads have been synthesized to study proton-coupled electron transfer (PCET) reactions induced by photoexcitation. High-potential porphyrins have been chosen to model P680, the photoactive chlorophyll cluster of photosynthet

The use of carbohydrate thiolates for facile, high-yielding, regio- and stereoselective nucleophilic substitution reactions of complex pentafluorophenyl-substituted porphyrinoids is reported. The title reaction has successfully been applied to calix[4]phy
C2 symmetric borneol-porphyrin hybrids: Synthesis, characterization, electronic structure and their anti-cancer behaviors
Dong, Xinyi,Fang, Xianying,Fu, Bo,Liang, Xu,Xu, Haijun,Yu, Xiaoxiao,Zhang, Zhen,Zhu, Weihua
, (2020/09/17)
A series of five C2 Symmetric A2B2 type borneol-porphyrin hybrids have been synthesized and characterized. Moreover, a detailed analysis of their optical and redox properties was carried out by comparing the results obtained via optical spectroscopy and electrochemistry. The current results demonstrated that the meso borneol-substitutions excitation coupled strongly with porphyrin core that leads to significant CD signals in the Soret band region, and molecular anti-cancer behaviors were also investigated.
