A balanced treatment of static and dynamic correlation in free- and Mg-porphyrin [PDF]

arXiv, 2020
We present an ab-initio dynamical configuration interaction (DCI) study of free- and Mg-porphyrin. DCI is a recently developed active space theory based on the L\"owdin downfolding technique. In the active space, static correlation is described exactly with full configuration interaction.

Toward Personalized Stationary Chromatography Phases: Equipping Commercial Silica Phases with Selected Peptide‐Based Binding Domains to Tailor Affinity

Advanced Materials Interfaces, EarlyView.
The 7‐mer peptide motifs QFFLFFQ, QFFEFFQ, and QFQQSFF, known as good, medium, and poor binders for the photosensitizers m‐THPC and Chlorin E6 are covalently immobilized on commercial amino‐functionalized silica particles by inverse electron‐demand Diels‐Alder ligation.

Effect of Antiepileptic Drugs on the Urinary Excretion of Porphyrins in Non-porphyric Subjects

Journal of Pharmacological Sciences, 2005
The action of some anticonvulsant drugs as the causal agents of attacks of acute porphyria has been widely documented in the literature. However, little attention has been paid to the effect of these drugs on the urinary excretion of porphyrins in non ...

Porphyrins with combinations of 4-carboxyphenyl and 4-hydroxyphenyl substituents in meso-positions as anti-HIV-1 agents

Scientific Reports
A series of 4-carboxyphenyl/4-hydroxyphenyl meso-substituted porphyrins were synthesized, purified, and characterized. The compounds exhibited anti-HIV-1 activities, in vitro, under both non-photodynamic (non-PDT) and photodynamic (PDT) conditions ...

Single‐Crystal Organic Field‐Effect Transistors Based on 5,15‐Bisaryl‐Tetrabenzoporphyrins: Synthesis, Structure, and Charge Transport Properties

Advanced Materials Interfaces, EarlyView.
This study explores single‐crystal organic field‐effect transistors (SC‐OFETs) based on 5,15‐bisaryl‐tetrabenzoporphyrin derivatives. It highlights the impact of meso‐substituted groups on molecular packing and charge transport. Among the derivatives, C8Ph‐BP achieves the highest hole mobility (1.64 cm2 V−¹ s−¹) due to enhanced π‐stacking with ...

Triarylphosphonium BODIPY‐Based [2]Rotaxanes Nanoparticles for Light‐Driven Antibacterial Applications

Advanced Optical Materials, EarlyView.
New photosensitizers for light‐induced antimicrobial therapy are successfully synthesized and characterized. When dissolved in water, all compounds self‐assemble forming spherical aggregates with <100 nm dimensions. The nanoparticles show high photothermal conversion efficiency and demonstrate antimicrobial activity toward both Gram‐negative and Gram ...

Photochemical Preparation of (Aza‐)Indolines: Diastereoselective Synthesis and Polarity Reversal Strategy

Advanced Synthesis &Catalysis, Accepted Article.
Herein, we present the first light‐mediated, diastereoselective de novo synthesis for 2,3‐substituted indolines, a privileged scaffold in pharmaceuticals. The protocol was tested with various aryl and alkyl groups, maintaining high yields up to 85% across different substituents.

Doping single wall carbon nanotubes with differently charged porphyrins [PDF]

arXiv, 2008
Photoluminescence (PL) measurements of porphyrin-doped single wall carbon nanotubes (SWNT) were studied in sodium dodecylbenzenesulfonate (NaDDBS) aqueous dispersions. The PL spectra were used to draw PL maps were the maxima corresponds to absorption-emission excitonic processes related to (E11, E22) first Van Hove singularities of the SWNT electronic ...
