Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films
Advanced Functional Materials, EarlyView.The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations
Advanced Functional Materials, EarlyView.Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and
