Their porosity leads to a high surface area, making them suited for assisting processes, such as synthesis (especially carboxylation and electrolytic reduction), catalysis (particularly electrocatalysts and photocatalysis), and separation. Considering these features, carbon nanotubes, graphene oxide, and graphene quantum dots have been extensively investigated for pharmaceutical applications. Coming from either organic, inorganic or synthetic precursors, the nanoporous carbon composites are of great value as adsorbent for the removal of various pollutants. Apart from the removal of pollutants, nanopores serve to separate single stranded and double stranded DNA in solution and rapid DNA sequencing. While the size of the pores depends on the method used for preparation, from a usage standpoint, the nanopores are micropores (<span>(&lt; ! 2 ~ text {nm})</span>), mesopores (<span>(2 !- ! 50 ~text {nm})</span>) and macropores (<span>(&gt; ! 50 ~ text {nm})</span>). The methods of investigation related with nanoporous carbon materials often include X ray diffraction, scanning electron microscopy, fourier transform infrared spectroscopy, transmission electron microscopy, X ray photoelectron spectroscopy, thermogravimetric analysis and X ray powder diffraction.

Recently, <i>kinetic</i> control of these processes has attracted more interest. This review describes three approaches for the kinetic control of supramolecular systems based on coordination chemistry. The discussion first focuses on the kinetic control of guest uptake of host–guest systems. The guest binding kinetics (i.e., guest uptake/release rate) can be basically controlled by the change in the aperture sizes of the host molecules. The second part provides representative examples of unveiling guest uptake/exchange mechanisms for a variety of supramolecular host–guest systems, which is important for the rational design of host molecules and prediction of their specific functions for future studies. The kinetic control of metal-assisted self-assembly processes is also introduced in the last part. The discussion especially focuses on investigation of the self-assembly pathway, control of the kinetic stability of self-assembled complexes, and the speed tuning of self-assembly processes by modulating the individual metal–ligand exchange rate.</p></div>","PeriodicalId":54324,"journal":{"name":"Journal of Inclusion Phenomena and Macrocyclic Chemistry","volume":"103 5-6","pages":"161 - 188"},"PeriodicalIF":2.3,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10847-023-01190-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4580114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, to investigate the electrochemical behaviors of these complexes, cyclic voltammetry was used and found that the Fe^3+/2+ redox potential was systematically shifted in anodic direction with the increment of phenyl moieties on the [14]-membered N₄-macrocyclic core.

The combination of β-CD with poly(ethylene glycol) will benefit from PEG’s properties including high water solubility, nontoxicity, non-immunogenicity, biocompatibility, and biodegradability.

This interaction was found to lead to a bathochromic shift of the DPhB absorption bands and an increase in absorption. Using the first derivative spectra of solutions with a fixed concentration of DPhB (0.01 mM) and a variable concentration of β-CD (0–10 mM), the logarithms of binding constants for 1:1 and 1:2 complexes of DPhB with β-CD were determined with 95% confidence intervals at 25 °C: 4.13 (4.03–4.20) and 6.30 (4.72–6.59). To eliminate systematic errors, the assumption that the equilibrium CD concentration in solution was equal to its total concentration was not used in this study. The obtained value for the 1:1 complex is consistent with the value determined earlier by affinity capillary electrophoresis (ACE), while the constant for the 1:2 complex is slightly lower than that from ACE, which can be explained by a higher concentration of DPhB; however, the use of this concentration is reasonable to reduce the measurement error. DPhB was found to form micelles at pH 9.18 and the critical micelle concentration (CMC) measured was 0.13 mM. This is a possible reason why the experimental points obtained at higher concentrations of DPhB than CMC are not described within the framework of theories that take into account the formation of 1:1 or both 1:1 and 1:2 complexes.</p></div>","PeriodicalId":54324,"journal":{"name":"Journal of Inclusion Phenomena and Macrocyclic Chemistry","volume":"103 3-4","pages":"109 - 121"},"PeriodicalIF":2.3,"publicationDate":"2023-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10847-023-01182-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4727918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
