pH-Responsive Supramolecular Switch of Rationally Designed Dipyrroethene-Based Chromophore Herein, we present a strategy to access a novel class of pH-responsive, dual-state emissive (DSE), highly fluorescent pyrrole-based chromophores via diformylation of dipyrroethenes (DPE) followed by condensation with various anilines derivatives. The DPE-based chromophores exhibit a large Stokes’ shift and maintain good fluorescent quantum yields.

Synthesis of triphyrin(2.1.1)-triphyrin(2.1.1) homo dimers and bis-Re(i) triphyrin dimer complex† First examples of covalently linked triphyrin(2.1.1)-triphyrin(2.1.1) homo dimers connected via flexible alkoxy linkers at β-pyrrole positions were synthesized in 28–30% yields by reacting 2-bromo triphyrin(2.1.1) with three different alkane diols such as 1,2-ethanediol, 1,4-butanediol and 1,6-hexanediol in toluene under Pd2(dba)3/DPEphos catalyzed conditions by refluxing for 12–20 h. One of the...

White Light Emitting Single Halochromic Hydrazine Bridged Bis(3-Pyrrolyl BODIPY) Fluorophore In search of white light emitting fluorophores, a hydrazine bridged Schiff base compound, bis(3-pyrrolyl BODIPY) was synthesized by condensing readily available α-formyl 3-pyrrolyl BODIPY with hydrazine hydrate in CH3OH at reflux for 5 h followed by recrystallization. The bis(3-pyrrolyl BODIPY) was thoroughly characterized by HR-MS, 1D & 2D NMR and X-ray crystallography.
