Carbonization of covalent triazine-based frameworks via ionic liquid induction

Abstract: A series of porous organic polymers (POPs) were synthesized based on the tetrahedral 1,3,5,7-tetracyanoadamantane as the main building block. This synthetic exploration afforded a drastic porosity alteration/enhancement of the unveiled POPs.

“…3A and table S5, the C/N ratio of the CTFs-1 increases notably as a function of increasing synthesis temperature. This observation confirms a reduction in the nitrogen content with an increase in the synthesis temperature because of the partial carbonization of the framework (40,53). Similar to the CTF-1-400 material, the XPS characterization of the samples synthesized at higher temperatures displays the existence of four different types of nitrogen functionalities including still pyridinic nitrogen in the triazine rings (398.4 eV), as well as pyrrolic (400 eV), quaternary (401 eV), and oxidized N-O (404 eV) species (Fig.…”

“…MeO -CTF600 was prepared under ionothermal conditions using molten ZnCl 2 , acting both as a Lewis acid cyclotrimerization catalyst and as a reaction medium. Among various recipes of CTF preparation, the ZnCl 2 -mediated ionothermal route is most widely adopted as it results in CTFs with superior textural and functional properties with great tailorability derived via modulation of the ZnCl 2 /monomer ratio and the synthesis temperature. Recent reports have described that a higher molar ratio (≥10 equiv) of ZnCl 2 resulted in materials with rich structural and porous properties, which are most desirable for the high-capacity capture of small gases. , As per the available literature guidelines, in the present study, we have chosen a 10:1 molar ratio of ZnCl 2 to L OMe , and the cyclotrimerization reactions were performed for 48 h at a temperature of 600 °C. The resulted MeO -CTF600 material is completely insoluble in water and any organic solvents, including dilute acids and bases, indicating the formation of networks with excellent physicochemical stability, mandatory for any realistic applications.…”

“…Many of the aforementioned works are related to covalent triazine-based frameworks, the reason being their great potential for practical applications, for example, gas storage, separation, catalysis, and electronic devices, their high chemical and thermal stability, and their relatively easy and cheap synthesis. All these make CTFs stand out as promising materials for testing in a wide range of applications [92,93].…”
