only prompts the DAEs to form charge‐transfer complexes, but also restricts its intramolecular rotation to enhance fluorescence emission. In this CB[8]‐containing supramolecular system, the π‐conjugation is extended and its absorption is bathochromically shifted for visible light‐driven cyclization of DAEs. Meanwhile, the fluorescence of the supramolecular assembly can also be reversibly modulated by visible

The present invention relates to a group of novel electrochromic materials. More specifically, it relates to electrochromic materials based on either single or two-core viologen systems and the use of these viologen systems as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.

the conjugation of 4,4′-bipyridinium derivatives into peptide scaffolds. The methodology, based on the development of a solid-phase version of the Zincke reaction between activated pyridinium salts and amines, is able to produce the desired conjugates in a straightforward fashion, with the bipyridinium units attached at the N-terminus of peptides or at Lys side chains of N-terminal acetylated peptides

The light-driven reduction of protons for the production of molecular hydrogen in multicomponentsystems depends on electron relays such as viologens. We describe here the effect of viologens appended with guest moieties (adamantane or bile acid) on the efficiency of a system composed of a cyclodextrin-appended photosensitizer [Ir(ppy)2(pytl-βCD)]Cl [ppy = 2-phenylpyridine; pytl = 2-(1-substituted-1H-1
