Films of a water-soluble tetracationic porphyrin (TMPyP) and an insoluble phospholipid (DMPA), in a molar ratio TMPyP:DMPA ) 1:4, were transferred onto optically transparent indium tin oxide (ITO) electrodes, and cyclic voltammetry and visible spectroscopy were used to detected and quantify the presence of porphyrin on the ITO supports. We found the surface density of porphyrin deposited ranges...

Abstract Metal-organic frameworks (MOFs) are promising photocatalytic materials due to their high surface area and tuneability of electronic structure. We discuss here how engineer the band structures optical properties a family two-dimensional porphyrin-based MOFs, consisting M -tetrakis(4-carboxyphenyl)porphyrin ( -TCPP, where = Zn or Co) metal (Co, Ni, Cu Zn) paddlewheel clusters, with aim o...

Human sera were found to contain factors that stimulate and factors that inhibit porphyrin formation by cultured avian liver cells. The capacity of sera to stimulate or inhibit porphyrin formation varied in different hormonal states and in the porphyrias. Sera from 31 post partum women, eight of whom were not lactating, inhibited porphyrin formation to a mean level 30% below the level in contro...

Morphological selection of the self-assembled nanostructure of zwitterionic porphyrins between nanorod and nanosheet by the small displacement of the peripheral anionic position is demonstrated based on the J-aggregates of zwitterionic porphyrin isomers, meso-tetrakis(5-sulfonatothienyl)porphyrin diacid and meso-tetrakis(4-sulfonatothienyl)porphyrin diacid.

Dye sensitizers can significantly affect power conversion efficiency of dye-sensitized solar cells (DSSCs). Porphyrin-based dyes are promising sensitizers due to their performances in DSSCs. Here, based upon a N-fused carbazole-zinc porphyrin-free-base porphyrin triad containing an ethynyl-linkage (coded as DTBC), the novel porphyrin dyes named DTBC-MP and DTBC-TP were designed by varying the p...

Porphyrins are important macrocycles with applications in several areas including therapy, catalysis, and sensing. Strong nonlinear optical (NLO) responses the key to fully exploiting potential of these biocompatible molecules. We herein report that certain metal-alkynyl donor/nitro acceptor-functionalized porphyrins attractive candidates for NLO applications. show specific examples exhibit rec...

The intracellular microenvironment is essential for the efficiency of photo-induced therapies, as short-lived reactive oxygen species generated must diffuse through their intracellular surrounding medium to reach their cellular target. Here, by combining measurements of local cytoplasmic dissipation and active trafficking, we found that photosensitizers activation induced small changes in surro...

Abstract The decarboxylative coupling of diversely substituted benzoic acids with internal alkynes proceeds smoothly in the presence a [RhCl(cod)]2/1,2,3,4-tetraphenyl-1,3-cyclopentadiene catalyst system to selectively produce highly naphthalene derivatives. is applicable constructing anthracene and benzo­[c]thiophene frameworks through reactions naphthoic thiophene-2-carboxylic acids, respecti...

Derivatives of amino acids bearing a porphyrin moiety on a side chain were synthesized by coupling a porphyrin to a glutamic acid side chain; the utility of these compounds was demonstrated by their use in solid-phase synthesis of a peptide bearing a cationic porphyrin and by studying its DNA-binding properties.
