A highly efficient solution and solid state ESIPT fluorophore and its OLEDs application

We present herein the synthesis and the photophysics of 2,2’-bipyridine-3,3’-diol-5,5’-dicarboxylic acid ethyl ester (BP(OH)$_2$DCEt$_2$), an excited state intramolecular proton tranfer (ESIPT)-based fluorophore featuring two identical…

Photoinduced Architectural Transformation of Noncovalent Fluorescent Photochromic Organic Nanoparticles as Evidenced by Amplified Fluorescence Photoswitching

Dual nanoparticles endowed with emission photoswitching ability are produced by the flash coprecipitation of fluorophores and photochromes in water in order to investigate the mutual interplay between the self-assembled photoactive units as a…

Mechanical Modulation of the Solid‐State Luminescence of Tricarbonyl Rhenium(I) Complexes through the Interplay between Two Triplet Excited States

Mechanoresponsive luminescence (MRL) materials promise smart devices for sensing, optoelectronics and security. We present here the first report on the MRL activity of two ReI complexes, opening up new opportunities for applications in these fields…

Mechanofluorochromism of pyrenyl acrylates with different substitutional position and steric hindrance

Solid-state emission color change upon mechanical stimuli, known as mechanofluorochromism (MFC), is reported for pyrenyl acrylates. The C-1- and C-4-alkenylated pyrenes ((E)-Ethyl-3-(Pyren-1-yl)acrylate and (E)-Ethyl-3-(Pyren-4-yl)acrylate,…
