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 …
