Derivatized porphyrins and multi-porphyrin assemblies

, 2018
Porphyrin-containing multi-component systems have served a key role in the study of molecular assembly and supramolecular chemistry. These systems, however, are often very difficult to prepare and new synthetic strategies towards their preparation are of great interest;This work describes a series of thiol-derivatized porphyrins and the corresponding ...

Spatial Coordination Structure‐Driven Enzyme‐Like Selectivity in Single‐Atom Nanozymes

Advanced Materials, EarlyView.
Sun et al. reviews recent progress in enhancing the enzyme‐like catalytic selectivity of SAzymes through the rational design of their spatial coordination structures. They emphasize the structure‐activity relationships of various attributes of these coordination structures in promoting selective catalytic behavior, the strategic design of coordination ...

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 ...

Conformational switching of ethano-bridged Cu,H2-bis-porphyrin induced by aromatic amines

Beilstein Journal of Nanotechnology, 2015
Cu,H2-bis-porphyrin (Cu,H2-Por2), in which copper porphyrin and free-base porphyrin are linked together by an ethano-bridge, was dissolved in chloroform and spread at the air/liquid subphase interface of a Langmuir trough.

The identification of histidine ligands to cytochrome a in cytochrome c oxidase [PDF]

, 1985
A histidine auxotroph of Saccharomyces cerevisiae has been used to metabolically incorporate [1,3-15N2] histidine into yeast cytochrome c oxidase. Electron nuclear double resonance (ENDOR) spectroscopy of cytochrome a in the [15N]histidine-substituted ...

Azolium‐Porphyrin Electrosynthesis

ChemSusChem
AbstractElectrochemical oxidation of Zn(II) 2,7,12,17‐tetra‐tert‐butylporphyrin in the presence of a series of azole derivatives (1‐methylimidazole, 1‐vinyl‐1H‐imidazole, 2‐(1H‐imidazol‐1‐yl)pyridine, 1‐methylbenzimidazole, 1‐methyl‐1H‐1,2,4‐triazole, and benzothiazole) affords the corresponding meso‐substituted azolium‐porphyrins in very mild ...

Red Blood Cell Membrane‐Camouflaged Red Phosphorus‐Modified C3N4 for Enhanced Tumoral Photodynamic Therapy

Advanced Materials Interfaces, EarlyView.
Photodynamic therapy (PDT) faces clinical challenges due to poor tumor targeting and systemic toxicity. Herein, a biomimetic C3N4‐RP@RBCm nanoplatform is developed via erythrocyte membrane encapsulation, enabling CD47‐mediated immune evasion and EPR‐driven tumor accumulation.

Biocompatible Porphyrin Derivatives Electron Beam and Extreme Ultraviolet Photoresists: High Resolution and High Etch Resistance

Advanced Materials Interfaces, EarlyView.
Porphyrin derivatives are introduced for electron beams and extreme ultraviolet lithography. The lithographic performance of the novel CuTP‐4Epoxy photoresist is excellent, with a resolution of 18 nm in EBL and 20 nm in EUVL, and the photoresist also exhibits high etch resistance.
