Abstract:
Preparing artificial assemblies that can achieve multi-stimuli-responsive and multi-level transformations remains a huge challenge. Here, a pair of dynamic metal-organic tube isomers was prepared from a ligand with multiple coordination modes and flexible conformations. They can undergo multi-level transformations in response to different types of stimuli, including conformational isomerization driven by physical factors (e.g., concentration, temperature, and polarity), adaptive deformations driven by neutral guests, adaptive reconstructions induced by anionic templates. Notably, the guest-driven deformed tubes can continue to undergo reconstruction induced by the PF6 - template, and DMSO can simultaneously serve as a physical factor and a chemical template to continuously regulate isomerization and reconstruction of the dynamic tube. The dynamic tube can be used to regulate the stacking modes of encapsulated 1-formylpyrene and 1-acetylpyrene through adaptive deformations, thereby generating stable guest radicals, enhancing guest fluorescence and achieving white light emission.

02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

02:52Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
