C[6]CPPs exhibited rigid belt-shaped structures with deep cavities. Moreover, C[6]CPPs exhibited high HOMO energies and narrow energy gaps. An unclosed belt was further obtained, and it not only showed a similar narrow energy gap to those of the aromatic belts, but also displayed strong fluorescence property, which can play a vital role in the design and synthesis of new aromatic belts.

impact of such forces are rare, as it is difficult to disentangle electrostatic forces from simple electroniccoupling. To address this problem, the impact of Coulombic interactions in the successive removal of two electrons from a model set of spirobifluorenes, where the interchromophoric electroniccoupling is nonexistent, is quantitatively assessed. By systematically varying the separation of the bifluorene

This invention relates to a composition for use as a reactive medium in a reversible electrochromic display device. The reactive medium is placed between two electrically conductive electrodes of the device, at least one of the electrodes being transparent, the composition includes an anhydrous solvent and an oxidant/reductant pair in which the reductant is an electron acceptor, and the oxidant is a substituted fluorene compound.
