The formation of the porous gels is monitored with in situ small\u2010angle X\u2010ray scattering, in situ nuclear magnetic resonance spectroscopy (NMR), and NMR cryoporometry. The transition of the reaction solution to a solid gel is governed by the consumption of the phenolic monomer. Primary particle growth and nanopore formation proceed during this short time period and are completed when all resorcinol is consumed. The kinetics of these processes are temperature\u2010dependent and they are completed within 12\u2009min at 120\u2009\u00b0C and within 60\u2009min at 80\u2009\u00b0C. Extending the reaction time further results in enhanced cross\u2010linking of the polymer, as observed by solid\u2010state\n                    <jats:sup>13<\/jats:sup>\n                    C NMR spectroscopy. Extended reaction time, i.e., higher degree of polymer cross\u2010linking, enhances pore stability and reduces gel shrinkage during drying, resulting in xerogels with larger pore volume, larger external surface area, and larger average pore sizes. This work rationalizes molecular\u2010scale transformation of polymers with macroscopic properties, thus providing a rational tool for tuning aerogel\/xerogel performance through synthesis design.\n                  <\/jats:p>","DOI":"10.1002\/smsc.202500460","type":"journal-article","created":{"date-parts":[[2025,11,18]],"date-time":"2025-11-18T15:16:05Z","timestamp":1763478965000},"source":"Crossref","is-referenced-by-count":2,"title":["Comprehensive Analysis of Key Parameters Determining Formation and Structural Properties of Sol\u2013Gel\u2010Derived Nanoporous Polymers"],"prefix":"10.1002","volume":"6","author":[{"given":"Abdurrahman","family":"Bilican","sequence":"first","affiliation":[{"name":"Department of Heterogeneous Catalysis Max\u2010Planck\u2010Institut f\u00fcr Kohlenforschung  Kaiser\u2010Wilhelm\u2010Platz 1 45470 M\u00fclheim an der Ruhr Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priyanka","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Heterogeneous Catalysis Max\u2010Planck\u2010Institut f\u00fcr Kohlenforschung  Kaiser\u2010Wilhelm\u2010Platz 1 45470 M\u00fclheim an der Ruhr Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8654-9867","authenticated-orcid":false,"given":"Glen J.","family":"Smales","sequence":"additional","affiliation":[{"name":"Institute for Inorganic Chemistry Graz University of Technology  Stremayrstra\u00dfe 9\/IV 8010 Graz Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8171-9399","authenticated-orcid":false,"given":"Markus","family":"Leutzsch","sequence":"additional","affiliation":[{"name":"Department of Nuclear Magnetic Resonance Spectroscopy Max\u2010Planck\u2010Institut f\u00fcr Kohlenforschung  Kaiser\u2010Wilhelm\u2010Platz 1 45470 M\u00fclheim an der Ruhr Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6709-5057","authenticated-orcid":false,"given":"Christophe","family":"Far\u00e8s","sequence":"additional","affiliation":[{"name":"Department of Nuclear Magnetic Resonance Spectroscopy Max\u2010Planck\u2010Institut f\u00fcr Kohlenforschung  Kaiser\u2010Wilhelm\u2010Platz 1 45470 M\u00fclheim an der Ruhr Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heike","family":"Ehmann","sequence":"additional","affiliation":[{"name":"Anton Paar GmbH  Anton\u2010Paar\u2010Str. 20 8054 Graz Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Armin","family":"Moser","sequence":"additional","affiliation":[{"name":"Anton Paar GmbH  Anton\u2010Paar\u2010Str. 20 8054 Graz Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Weidenthaler","sequence":"additional","affiliation":[{"name":"Department of Heterogeneous Catalysis Max\u2010Planck\u2010Institut f\u00fcr Kohlenforschung  Kaiser\u2010Wilhelm\u2010Platz 1 45470 M\u00fclheim an der Ruhr Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5166-1202","authenticated-orcid":false,"given":"Wolfgang","family":"Schmidt","sequence":"additional","affiliation":[{"name":"Department of Heterogeneous Catalysis Max\u2010Planck\u2010Institut f\u00fcr Kohlenforschung  Kaiser\u2010Wilhelm\u2010Platz 1 45470 M\u00fclheim an der Ruhr Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,18]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01139044"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1557\/PROC-270-3"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/ma13010119"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2095-4956(13)60025-X"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijhydene.2010.09.018"},{"key":"e_1_2_9_7_1","first-page":"87","volume-title":"Organic and Carbon Gels, Advances in Sol\u2010Gel Derived Materials and Technologies","author":"Arenillas A.","year":"2019"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsomega.3c05824"},{"key":"e_1_2_9_9_1","first-page":"C4\u201033","volume":"50","author":"Pekala R.
