Symmetric Metal Organic Framework‐Plasmonic Architectures for Reversible and High‐Sensitivity Optical Sensing

open access: yesSmall, EarlyView.
This work presents a plasmonic sensing platform combining surface lattice resonances (SLRs) in 2D metal nanoparticle gratings with ZIF‐8 MOF films. The plasmonic grating is easily and scalably produced from template‐assisted assembly of metal colloids, which is fully compatible with MOF growth. The resulting MOF‐plasmonic structure allows for a dynamic

Modular Donor‐Acceptor Diradicaloids Based on an Electron Deficient N‐Heteroacene Acceptor

open access: yesSmall, EarlyView.
This work presents a modular approach to donor‐acceptor‐donor (D‐A‐D) diradicaloids that show systematic evolution of their energy gaps, singlet‐triplet splittings, and diradical character (y). The correlation of (opto)electronic, spin, and magnetic properties with high‐fidelity theoretical investigations provides clear connections between the degree ...

Anion Component Engineering of Spontaneous Perovskite Passivators for Energy Alignment Modulations in Perovskite Solar Cells

open access: yesSmall, EarlyView.
n‐Octylammonium bis(fluorosulfonyl)imides (OA‐FSI, OA‐TFSI, and OA‐PFSI), used as additives for spiro‐OMeTAD hole‐transport materials (HTMs) in perovskite solar cells (PSCs), allow spontaneous perovskite passivation during HTM deposition. Anion component engineering of the OA‐bis(fluorosulfonyl)imides effectively modulate energy alignment in PSCs via ...
