Light-irradiation of these electron-responsive supramolecular materials triggers a photo-induced electron transfer yielding isolated \u03c0-radicals and dimers of radicals. The photoreduction events and the associated dimerization steps trigger a large-scale reorganization occurring within the supramolecular network yielding aggregates or gels depending on the irradiation conditions (power, duration). Detailed electrochemical, spectro-electrochemical and photochemical analyses were conducted to understand the mechanisms at stakes in these light-induced aggregation and gelation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Our article is available to read at ECS Adv.
