Paragraph 0258, (2018/07/31)
Electrochromic compounds and optical articles containing them The present invention relates to a group of novel electrochromic compounds. More specifically, it relates to electrochromic compounds comprising one or several pyridinium rings and the use of these compounds as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.

The self-assembly of a cuboctahedral M12L24 complex is traced by time-dependent NMR spectroscopy and mass spectrometry. The metastable intermediate structures that exist during the self-assembly process are not a chaotic mixture of numerous species, but instead are geometrically restricted. Short-lived M8L16 (D4d) and relatively long-lived M9L18 (D3h) are fully characterized as major intermediates. Employing a ligand with a smaller bend angle (112°) allows these two species to be kinetically trapped and more clearly observed by NMR spectroscopy. X-ray crystallography shows that M9L18 has the framework topology predicted by geometric discussion.

The self-organization of multicomponent supramolecular systems involving a variety of two-dimensional (2D) polygons and three-dimensional (3D) cages is presented. Nine self-organizing systems, SS1-SS9, have been studied. Each involve
