Photochromism and Dual-Color Fluorescence in a Polyoxometalate-Benzospiropyran Molecular Switch

The photophysical properties of a Keggin-type polyoxometalate (POM) covalently bounded to a benzospiropyran (BSPR) unit have been investigated. These studies reveal that both closed and open forms are emissive with distinct spectral features (λem …

Photophysics of self-assembled luminophore-perovskite systems

During the past few years hybrid organic-inorganic perovskites (HOIPs) have attracted much interest as solution-processed semiconductors with high potentialities in optoelectronics. On the one hand “3D” HOIPs such as CH3NH3PbI3 have shown their…

Polymorphism, Mechanofluorochromism, and Photophysical Characterization of a Carbonyl Substituted Difluoroboron-β-Diketone Derivative

Difluoroboron-β-diketones are known to exhibit very promising mechanochromic luminescence but a greater understanding of these materials and their mechanor-esponsive properties is still desirable. Here we demonstrate that a combination of…

Identification of acylation products in SHAPE Chemistry

SHAPE chemistry (selective 2’-hydroxyl acylation analyzed by primer extension) has been developed to specifically target flexible nucleotides (often unpaired nucleotides) independently to their purine or pyrimidine nature for RNA secondary structure…

Fast growth of monocrystalline thin films of 2D layered hybrid perovskite

Hybrid organic-inorganic perovskites are on the way to deeply transform the photovoltaic domain. Likewise, it recently appears that this class of materials have a lot of assets for other optoelectronic applications. One key aspect is to be able to…

Excitonic emission of hybrid lead iodide perovskite single crystals.

Since 2012, the 3D Hybrid Organic Perovskites of formula CH3NH3PbI3 and their derivatives represent a “material breakthrough” for photovoltaïcs: in only 3 years, the efficiency of 3D HOP-based solar cells has progressed from 12% to more than 20%…

Interaction processes of ciprofloxacin with graphene oxide and reduced graphene oxide in the presence of montmorillonite in simulated gastrointestinal fluids

This study investigated the interaction processes of ciprofloxacin (CIP) with graphene oxide (GO) and reduced GO (rGO) in presence of montmorillonite (Mont) in simulated gastrointestinal fluids. The order of CIP adsorption affinity was rGO+Mont >…
