Recent Advances in Fuel‐Driven Molecular Switches and Machines

Abstract

significant steps towards mimicking the natural machines and may offer a platform for advancing new applications by providing temporal control. This review summarises the recent progress and blueprint of autonomous fuel-driven off-equilibrium molecular switches and machines.

From construction to application of a new generation of interlocked molecules composed of heteroditopic wheels

“…can be triggered by external stimuli (cation/anion, acid/base) to fabricate smart molecular machineries, as reported by several groups. 68 In this subsection, we briefly summarize the effects of mechanical bonds on the dynamic properties of heteroditopic wheel-based MIMs.…”

Inclusion and Non‐Inclusion Complexes between Curcumin and β‐Cyclodextrin with High‐Curcumin Loading and Enhanced Aqueous Solubility Obtained by Mechanochemistry

“…ICs may find applications in catalysis, promoting highly selective and efficient reactions due to the confinement, [2] in sensing and detecting specific analytes for environmental monitoring, [3] or medical diagnostics, [4] in chiral recognition [5] or in sophisticated molecular switches and machines, taking advantage of reversible conformational changes upon certain stimuli to produce controlled movements with potential applications in nanotechnology and molecular computing. [6,7] Specifically in the nanomedicine field, the formation of ICs has become a pillar, modifying the physicochemical and spectroscopic properties of biologically active molecules as guests. The primary achievement is the improvement of the guests' stability, solubility, and bioavailability.…”

Tunable cyclic operation of dissipative molecular switches based on anion recognition

“…16,17 Chemical fuels [18][19][20][21][22][23] and photo-irradiation [24][25][26][27] are two of the most prevailing forces to drive artificial dissipative systems, which undergo either back and forth or cyclic motion. 28 Notably, chemical fuels have the potential to be stored and transported, enabling manufactured dissipative systems that operate autonomously over space and time. [29][30][31][32][33][34][35][36] In particular, molecular switches based on anion recognition are important artificial systems to mimick dissipative biological processes, involving ATPs and other biomolecules.…”
