Iodine clocks: applications and untapped opportunities in materials science

Abstract

Iodine clocks are fascinating nonlinear chemical systems with a glorious past and a promising future. The dynamic removal of iodine from these systems by different means can have important consequences for their reaction dynamics, and could be exploited for time-controlled autonomous dissipative self-assembly. Here, the untapped opportunities offered by iodine clocks for materials science, especially for the time-programming of supramolecular assembly and sol-gel transition, are reviewed and discussed with the hope of arousing the interest on the subject and stimulating new research directions.
