In this work, we have designed and synthesized a D\u2212\u03c0\u2212A system constituting ester\u2010flanked quinolines and functionalized triarylamines (TAA) through a single\u2010step cross\u2010coupling reaction to fabricate memory devices via Write\u2010Once Read\u2010Many times (WORM) non\u2010volatile memory. Structure\u2010property relationships are reconnoitered for these conjugated D\u2212\u03c0\u2212A systems through a series of UV, fluorescence, XRD, DFT, and memory characterizations. The UV and CV data show efficient charge transfer with intramolecular charge transfer occurring at 407\u2013417\u2005nm and a short band gap of 2.56\u20132.65\u2005eV. An enhancement in the resistive switching behavior of the memory devices is observed for the compounds with simple TAA\u2010quinoline and tert\u2010butylphenyl substituted TAA and fluorophenyl substituted quinoline due to balanced charge distribution in the compounds. This enhanced switching induces an on\/off ratio of 10<jats:sup>3<\/jats:sup> by generating a highly ordered arrangement in the thin films. The HOMO, LUMO levels, and the ESP images together estimate a charge transfer and charge trapping as the plausible mechanism for the solution\u2010processable WORM memory devices. The longer retention time (10<jats:sup>3<\/jats:sup>\u2005s) and lower threshold voltages (\u22121.21\u2013\u22122.12\u2005V) of the devices makes them intriguing compounds for memory applications.<\/jats:p>","DOI":"10.1002\/chem.202202569","type":"journal-article","created":{"date-parts":[[2022,11,17]],"date-time":"2022-11-17T12:31:19Z","timestamp":1668688279000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Enhancing the Resistive Switching Behavior of WORM Memory Devices Using D\u2212\u03c0\u2212A Based Ester\u2010Flanked Quinolines**"],"prefix":"10.1002","volume":"29","author":[{"given":"Varghese M.","family":"Angela","sequence":"first","affiliation":[{"name":"Organic Electronics Division, Department of Chemistry Central University of Tamil Nadu  Thiruvarur 610 005 India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deivendran","family":"Harshini","sequence":"additional","affiliation":[{"name":"Organic Electronics Division, Department of Chemistry Central University of Tamil Nadu  Thiruvarur 610 005 India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anshika","family":"Anjali","sequence":"additional","affiliation":[{"name":"Organic Electronics Division, Department of Chemistry Central University of Tamil Nadu  Thiruvarur 610 005 India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Predhanekar M.","family":"Imran","sequence":"additional","affiliation":[{"name":"Department of Chemistry Islamiah College  Vaniyambadi 635 752 India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nattamai S.
