Conformations of 2,2′-bipyrrole π-systems having an electron-donating site at one terminal and electron-accepting site at the other terminal in the ground and excited states

Various symmetrical and unsymmetrical 1,1′,5,5′-tetraaryl-2,2′-bipyrroles (1, 5, and 10) were synthesized. From their UV-VIS absorption and fluorescence spectra, the conformations of the central 2,2′-bipyrrole systems were considered as follows. These com

Novel 1,1′,5,5′-tetraaryl-2,2′-bipyrroles: Their synthesis and physical properties

We report a new type of 2,2′-bipyrrole derivatives that bear four aryl groups at the 1, 1′, 5 and 5′ positions. These compounds were synthesized by two routes: (i) the reaction of 1,8-diaryl-2,7-ditosyl-1,7-octadiene-3,5-diynes (4) with anilines was perfo
