Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Self‐Assembled Heterosymmetric Structure with Tunable Polarization Optics for Reversible Matrix Encryption

open access: yesAdvanced Functional Materials, EarlyView.
Sustainable films with heterosymmetric structures, harmoniously integrating symmetry and asymmetry, are fabricated using cellulose nanocrystals and hydrophilic nanolignin via evaporation‐induced self‐assembly, which exhibit excellent multiple polarization optical properties.

All‐Optical Electric Field Sensing with Nanodiamond‐Doped Polymer Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
The photoluminescence (PL) of fluorescent nanodiamonds (FNDs) in a polymer‐based capacitor device is sensitive to electric fields. When an external electric field is applied, the PL intensity of the negatively charged nitrogen‐vacancy center (NV‐) increases, while that of the neutrally charged NV center (NV0) decreases.

On‐Surface Indigo‐Based Bimolecular Coordination Networks with Programmable Regular or Vitreous Structure

open access: yesAdvanced Functional Materials, EarlyView.
A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...

Fabrication of Free‐Standing Undulating Graphene Oxide Modular Tapered Pipes Using the Marangoni Effect

open access: yesAdvanced Functional Materials, EarlyView.
Free‐standing undulating graphene oxide (GO) modular tapered pipes fabricated based on the Marangoni effect and viscosity control are modular tubular structures that effectively utilize the lamination process between GO films. This novel tubular GO structure allows for the realization of various forms through the assembly of identical modules ...
