Diketopyrrolopyrrole Derivatives as Photosensitizing Agents against Staphylococcus aureus

open access: yesPhotochemistry and Photobiology, 2022
AbstractDiketopyrrolopyrrole (DPP) derivatives containing sulfonamide (Sulfonamide‐DPP), pyridyl (Dipyridyl‐DPP) and N‐methylpyridyl (MePyridyl‐DPP) substituents were assessed as antibacterial photosensitizers. Non‐charged DPPs showed an intense absorption band centered at about 480 nm and green fluorescence emission (ΦF ~ 0.7) in acetonitrile.

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

open access: yesAdvanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.
