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

open access: yesAdvanced 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 ...

First-principle molecular dynamics with ultrasoft pseudopotentials: parallel implementation and application to extended bio-inorganic system

open access: yes, 2003
We present a plane-wave ultrasoft pseudopotential implementation of first-principle molecular dynamics, which is well suited to model large molecular systems containing transition metal centers.

Rationalizing the Unexpected Inefficiencies of 3D Porphyrin‐MOFs as Singlet Oxygen Photosensitizers Against Botrytis cinerea

open access: yesAdvanced Materials Interfaces, EarlyView.
Unexpected results show that the singlet‐oxygen based antifungal activity of porphyrin‐based Metal‐Organic Frameworks is far below expectations while the standalone ligand is more efficient. We attribute these behaviours to inefficient exciton migration and gas diffusion leading to low singlet oxgyen concentrations at and beyond the MOF‐gas interface ...

Azolium‐Porphyrin Electrosynthesis

open access: yesChemSusChem
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 ...

Molecular Nanoarchitectonic Sensing Layer for Analysis of Volatile Fatty Acids in Bioreactor Headspaces Using a Nanomechanical Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
A porous crystalline sensing layer has been developed in conjunction with a nanomechanical sensor for the sensitive detection of volatile fatty acids (VFAs) in admixture at high relative humidity. The sensitive, selective sensor based on supramolecular design improves the economic viability of anaerobic digesters toward a carbon neutral society ...

Microlasers Made Entirely from Edible Substances

open access: yesAdvanced Optical Materials, EarlyView.
Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.
