Tetrazine molecules as efficient electronic diversion channel in 2D organic-inorganic perovskites

Taking advantage of an innovative design concept for layered halide perovskites with active chromophores acting as organic spacers, we present here the synthesis of two novel two-dimensional (2D) hybrid organic-inorganic halide perovskites…

Fluorescent molecular probe based optical fiber sensor dedicated to pH measurement of concrete

An optical fiber sensor based on a fluorescent molecular probe has been developed to measure the pH of cementitious materials, from the early stages of the material hydration. A fluorescent molecular probe, Naphth-AlkyneOMe is en-trapped in a cross…

Multi‐Directional Mechanofluorochromism of Acetyl Pyrenes and Pyrenyl Ynones

A series of acetyl pyrenes and pyrenyl ynones with and without tert-butyl groups showed distinct mechanofluorochromism (MFC). Four pairs of polymorphic solids were found out of six compounds and interestingly, each of them showed hypsochromic,…

Cyclometallated Pt(II) Complexes Containing a Functionalized Bis-Urea Alkynyl Ligand: Probing Aggregation Mediated by Hydrogen Bonds versus Pt...Pt and pi-pi Interactions

Neutral cyclometallated Pt(II) complexes [(C<^>Nt-Bu<^>Nt-Bu)Pt-R] (4-5) containing a bis-urea alkynyl (R) ligand have been prepared and fully characterized. The dichotomous nature of 4-5 makes it difficult to anticipate which…

Silafluorene as a promising core for cell-permeant, highly bright and two-photon excitable fluorescent probes for live-cell imaging

In this study, we report the synthesis, linear and non-linear photophysical studies and live cell imaging of two two-photon activatable probes based on a silafluorene core: SiFluo-V and SiFluo-L. Thanks to their quadrupolar (A-π-D-π-A) design, these…

A theoretical perspective on the electronic and optical properties of layered halide perovskites: Symmetry analysis of quantum-well electronic structure and charge/energy transfer processes beyond the quantum-well picture

Layered halide perovskites are a class of semiconductors produced via chemical approaches and showing unique opto-electronic properties. Pioneered by Prof. David Mitzi in the 1990s, these materials have a natural quantum-well electronic structure …

The effect of gold nanoparticle capping agents on 1O2 detection by singlet oxygen sensor green

Singlet Oxygen Sensor Green (SOSG) is the most widely used fluorescent probe for detecting singlet oxygen (1O2). 1O2 can be efficiently produced by exciting the surface plasmon of gold nanoparticles with laser pulses. However, gold nanoparticles are…
