The effect of TMe-\u03b2CD or TMe-\u03b3CD encapsulation of PEDOT backbones on the molecular weight, thermal stability, and solubility were investigated in depth. UV\u2013vis absorption, fluorescence (FL), phosphorescence (PH), quantum efficiencies, and lifetimes in water and acetonitrile were also explored, together with their surface morphology and electrical properties. Furthermore, dynamic light scattering was used to study the hydrodynamic diameter (DH) and z-potential (ZP-\u03b6) of the water soluble fractions of PEDOT\u2219TMe-\u03b2CD and PEDOT\u2219TMe-\u03b3CD. PEDOT\u2219TMe-\u03b2CD and PEDOT\u2219TMe-\u03b3CD exhibited a sharp monodisperse peak with a DH of 55 \u00b1 15 nm and 122 \u00b1 32 nm, respectively. The ZP-\u03b6 value decreased from \u221231.23 mV for PEDOT\u2219TMe-\u03b2CD to \u221220.38 mV for PEDOT\u2219TMe-\u03b3CD, indicating that a negatively charged layer covers their surfaces. Surface pressure\u2013area isotherms and Brewster angle microscopy (BAM) studies revealed the capability of the investigated compounds to organize into sizeable and homogeneous 2D supramolecular assemblies at the air\u2013water interface. The control of the 2D monolayer organization through the thermodynamic parameters of PEDOT\u2219TMe-\u03b2CD and PEDOT\u2219TMe-\u03b3CD suggests potential for a wide range of optoelectronic applications.<\/jats:p>","DOI":"10.3390\/ma16134757","type":"journal-article","created":{"date-parts":[[2023,7,3]],"date-time":"2023-07-03T00:49:27Z","timestamp":1688345367000},"page":"4757","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Novel Insight into the Photophysical Properties and 2D Supramolecular Organization of Poly(3,4-ethylenedioxythiophene)\/Permodified Cyclodextrins Polyrotaxanes at the Air\u2013Water Interface"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5933-8976","authenticated-orcid":false,"given":"Alae","family":"El Haitami","sequence":"first","affiliation":[{"name":"Laboratory of Physical Chemistry of Polymers and Interfaces, CY Cergy Paris Universit\u00e9, F95000 Cergy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0292-6267","authenticated-orcid":false,"given":"Ana-Maria","family":"Resmerita","sequence":"additional","affiliation":[{"name":"\u201cPetru Poni\u201d Institute of Macromolecular Chemistry, Romanian Academy, Grigore Ghica Voda Alley, 41A, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura Elena","family":"Ursu","sequence":"additional","affiliation":[{"name":"\u201cPetru Poni\u201d Institute of Macromolecular Chemistry, Romanian Academy, Grigore Ghica Voda Alley, 41A, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3459-7015","authenticated-orcid":false,"given":"Mihai","family":"Asandulesa","sequence":"additional","affiliation":[{"name":"\u201cPetru Poni\u201d Institute of Macromolecular Chemistry, Romanian Academy, Grigore Ghica Voda Alley, 41A, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie","family":"Cantin","sequence":"additional","affiliation":[{"name":"Laboratory of Physical Chemistry of Polymers and Interfaces, CY Cergy Paris Universit\u00e9, F95000 Cergy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3401-6425","authenticated-orcid":false,"given":"Aurica","family":"Farcas","sequence":"additional","affiliation":[{"name":"\u201cPetru Poni\u201d Institute of Macromolecular Chemistry, Romanian Academy, Grigore Ghica Voda Alley, 41A, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pankow, R.M., and Thompson, B.C.
