Multidimensional Dynamic Control of Supramolecular Phthalocyanine Gear: A Self-Assembly System Responding to Solvent, Temperature, and Hydrostatic Pressure

Smart supramolecular materials that respond toward various external stimuli hold great promise for various applications in molecular memories, logic gates, and drug delivery systems. In this study, the active control over the self-assembly of phathalocyanine gear was achieved by combining temperature and hydrostatic pressure stimuli with a dynamic solvent. Eventually, we found that the supramolecular gear can behave as a logic gate; “engaged” (+1) or “not” (0) state is switchable by solvent, temperature, and hydrostatic pressure. This paper describes not only new aspects for the rational design of smart stimuli-responsive supramolecular materials but also the significance of multidimensional dynamic control.

At t = 0,  and l represent the molar extinction coefficient of the monomer and cell length, respectively.
The D values determined from Figures S13 and S14 were processed using Eq.(S6) to obtain Figure S15.
Finally, the fitting results presented in Figure S15 produced kdim values at various pressures.Table S2.
