A simple, selective and sensitive Cu(II) probe is highlighted. It is noteworthy that this novel probe induces triple channel (colorimetric, fluorogenic and voltammetric) response to Cu(II) ions, which makes it viable for practical applications.

The controlled preparation of higher order oligopyrrolic species holds broad utility across the chemical and material sciences. Here, we describe the gram-scale synthesis of a bench-stable 5,5″-unsubstituted terpyrrole in excellent yield via a tandem Suzuki cross-coupling with in situ deprotection. The solution and solid-state stability as well as UV–vis, fluorescence, and single crystal X-ray diffraction

cyclo[2]carbazole[2]pyrrole (2) consisting of two carbazoles and two pyrroles has been synthesized by directly linking the carbazole 1- and 8-carbon atoms to the pyrrole α-carbon atoms. Macrocycle 2 is an extensively conjugated 16-membered macrocyclic ring that is fixed in a pseudo-1,3-alternate conformation. This provides a preorganized anion binding site consisting of two pyrrole subunits. 1H NMR spectroscopic

The controlled preparation of oligopyrroles can be enabling for both chemistry and materials science. In this study, we present a straightforward one-potsynthesis that allows access to a series of α,α′-linked arene-bridged oligopyrrolic dialdehydes. The method relies on the Pd(0)-catalyzed tandem Suzuki cross-coupling of heterocyclic precursors. Access to the present diformyl oligopyrroles enables

A novel directly-linked donor-acceptor-donor (D-A-D) type system, which is based on 2,3-dihydro-1H-pyrrolo[3,4-d]pyridazine-1,4(6H)-dione as the A unit and thiophene as the D units, respectively, is designed, synthesized, and characterized by spectroscopic methods. This novel D-A-D system can be used for the fluorogenic detection of Cu2+ among other ions. (C) 2012 Elsevier Ltd. All rights reserved.
