Control of self-assembly is significant to the preparation of supramolecular materials, but the control of hydration, responsiveness, dimension, catalysis of macrocyclic amphiphiles in an atom-economic manner is still a great challenge. The herein presented 527 Da low-molecular-weight macrocyclic amphiphile was fabricated by utilizing the selenium-containing crown ether as a hydrophobic motif together with guanidinium group as the hydrophilic moiety. The resulting benzo[21]crown-7 based macrocyclic amphiphile readily forms a redox-responsive solid nanoparticles in water, which can further interconnect into wrinkled pattern on-surface, as well as exhibits as a nanozyme for catalyzing disulfid bond formation. The present work highlights the great potential of guanidinium-and selenium-containing crown ethers for the control of functional assemblies. 展开更多

Constitutionally adaptive chemistry of selenium-containing crown ethers(CEs) offers a new platform for controlling/switching the hydration of bolaamphiphile skeletons in water in an effective and simple manner by the virtue of covalent bonding. The adaptive behaviour of the macrocyclic bolaamphiphiles(transformations between C7SeBola and C7SeOBola) in response to redox environment was found to be a decisive factor. 展开更多

A novel diselenide-containing crown ether(BC7Se_(2))was fabricated,which can polymerize to form cyclic oligomers through intermolecular dynamic covalent reaction by irradiation of visible light.The size and distribution of oligomers are related to the monomer concentration.The decomposition reaction of oligomers is controlled by topology and solvents.Furthermore,potassium cation can inhibit the polymerization of BC7Se_(2)and accelerate the decomposition of oligomers. 展开更多
