Epitaxial Growth of Highly Oriented Fibers of Semiconducting Polymers with a Shish-Kebab-Like Superstructure

Highly oriented fibers of regioregular poly(3-alkylthiophene)s (P3ATs) showing a ldquoshish-kebabrdquo morphology are prepared by oriented epitaxial crystallization in a mixture of 1,3,5-trichlorobenzene (TCB) and pyridine. The superstructure of the…

New Hindered BODIPY Derivatives: Solution and Amorphous State Fluorescence Properties

Four new hindered boron-dipyrromethene (BODIPY) dyes have been engineered and synthesized by modification of the pyrrole substituents. The chromophores were designed to shift their absorption and emission wavelengths to the red and to show…

Laser operation in non-doped thin films made of a small-molecule organic red-emitter

Stimulated emission in small-molecule organic films at a high dye concentration is generally hindered by fluorescence quenching, especially in the red region of the spectrum. Here we demonstrate the achievement of high net gains (up to 50 cm-1)…

Synthesis of triazole-linked β-C-glycosyl dimers as inhibitors of PTP1B

A multichromophoric glucopyranoside bearing three dicyanomethylenepyran (DCM) fluorophores and one diarylethene (DAE) photochrome has been prepared by Cu(I)-catalyzed alkyne???azide cycloaddition reaction. The fluorescence of was switched off upon…

Photophysics of cyclic multichromophoric systems based on ??-cyclodextrin and calix[4]arene with appended pyridin-2???-yl-1,2,3-triazole groups

The effect of the four isomeric forms of DCM on its emission and photoreactivity is highlighted, based on a suitable combination of experimental data (structures and spectroscopy) and theoretical computations (DFT and spin???flip TDDFT).
