Investigation of the Effect of the Trifluoropropynyl Ligand on Pt(N^C^N)X (X = Cl, C₂CF₃) Complexes

Crystals
The tuning of the luminescent properties of PtII complexes for possible use in organic light-emitting diodes (OLEDs) and sensing applications is commonly achieved by altering the electronic properties of the ligands.

Observation of Circularly Polarized Luminescence of the Excimer from Two Perylene Cores in the Form of [4]Rotaxane.

Chemistry, 2018
A perylene-based [4]rotaxane was synthesized by the Sonogashira coupling of the 2:2 inclusion complex consisting of two alkynylperylenes and two γ-cyclodextrins with terphenyl-type stopper molecules. The [4]rotaxane showed orange emission attributable to

Tailored Nickel Oxide Interfacial Layers Unlock Enhanced Charge Dynamics in LaTiOxNy Thin Film Photoanodes

Advanced Materials Interfaces, EarlyView.
This study highlights the importance of designing photoanode architectures for solar water splitting that align intrinsic material properties with functional interfaces to optimize the extraction of photogenerated charges. The incorporation of NiOx surface layers in LaTiO2.5N0.5 (LTON) thin film photoanodes exemplifies this approach by leveraging band ...

Room Temperature Synthesis and Photopatterning of Mesoporous Titanium Dioxide Thin Films

Advanced Materials Technologies, EarlyView.
A nanofabrication strategy combining deep‐UV photolithography with block copolymer self‐assembly enables direct patterning and mineralization of mesoporous TiO2 thin films at room temperature. Photocatalytic titanium oxo‐clusters promote polymer degradation under UV irradiation, enabling multiscale control over porosity, film thickness, and lateral ...

Experience of using an excimer lamp equipped with UVB dose control system in dermatology

Biomedical Photonics, 2020
Intermediate ultraviolet (UVB) therapy is considered a relatively safe method of treating skin diseases with an autoimmune component in development compared to medical drug methods, including PUVA therapy. This is due to the small depth of penetration of

Nanoporous Microelectrodes for Neural Electrophysiology Recordings in Organotypic Culture

Advanced Materials Technologies, EarlyView.
The highly porous microelectrodes have been designed and printed on culture membranes, allowing to record electrophysiological neural activity for rodent brain slices. To keep the biocompatible nanoporous structure, the microelectrodes and insulative layer are fabricated on the bottom of culture membranes with only small connector pads added on the top.

Reimagining o‐Carborane‐Based Fluorophores: Charge‐Transfer from Boron Substituents Triggers Aggregation‐ and Crystallization‐Induced Emission

Angewandte Chemie, EarlyView.
This work reports, for the first time, aggregation‐ or crystallization‐induced emission in boron‐substituted carboranes, which was driven by photoinduced charge‐transfer from fluorophore attached via boron vertices. The emission properties can be tuned by varying the substituents, expanding design strategies for luminescent materials.

Disrupting J‐Aggregation in Triazatruxene Dimers to Develop Responsive Luminescent Inks for Anti‐Counterfeiting Applications

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...
