From the monomer 4,4\u2032-(phenazine-5,10-diyl)dibenzonitrile (pBN), new pBN-CTFs were synthesized using the ionothermal method with a variation in temperature (400 and 550 \u00b0C) and the ZnCl2-to-monomer ratio (10 and 20). N2 adsorption yielded BET surface areas up to 1460 m2g \u22121. The pBN-CTFs are promising CO2 adsorbents and are comparable to other benchmark CTFs such as CTF-1 with a CO2 uptake of pBN-CTF-10-550 at 293 K of up to 54 cm3 g\u22121 or 96 mg g\u22121, with a CO2\/CH4 IAST selectivity of 22 for a 50% mixture of CO2\/CH4. pBN-CTF-10-400 has a very high heat of adsorption of 79 kJ mol\u22121 for CO2 near zero coverage in comparison to other CTFs, and it also stays well above the liquefaction heat of CO2 due to its high microporosity of 50% of the total pore volume.<\/jats:p>","DOI":"10.3390\/molecules30153110","type":"journal-article","created":{"date-parts":[[2025,7,24]],"date-time":"2025-07-24T14:11:44Z","timestamp":1753366304000},"page":"3110","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Synthesis and Characterization of Covalent Triazine Frameworks Based on 4,4\u2032-(Phenazine-5,10-diyl)dibenzonitrile and Its Application in CO2\/CH4 Separation"],"prefix":"10.3390","volume":"30","author":[{"given":"Hanibal","family":"Othman","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Anorganische Chemie und Strukturchemie, Heinrich-Heine-Universit\u00e4t D\u00fcsseldorf, 40204 D\u00fcsseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Oestreich","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Anorganische Chemie und Strukturchemie, Heinrich-Heine-Universit\u00e4t D\u00fcsseldorf, 40204 D\u00fcsseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vivian","family":"K\u00fcll","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Anorganische Chemie und Strukturchemie, Heinrich-Heine-Universit\u00e4t D\u00fcsseldorf, 40204 D\u00fcsseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcus N.
