This thesis investigates the effect of blending poly[2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene] (PBTTT-C14) with various imidazolium-based ionic liquids ([C12mim][TFSI], [C8mim][TFSI], and [C6mim][TFSI]) to control local order and enhance material functionality. Morphological, thermal, and optical characterizations were performed across\u0026nbsp;a range of\u0026nbsp;PBTTT:IL blending ratios, revealing the emergence of phase-separated morphologies at higher IL concentrations and shifts in thermal transition temperatures. UV-Vis\u0026nbsp;spectroscopy demonstrated\u0026nbsp;red-shifts and vibronic coupling enhancements, signifying tunable electronic properties. The introduction of vacuum compression molding into the differential scanning calorimetry sample preparation process improved thermal contact, enabling more precise analysis of phase transitions. From this work, findings suggest that the local order and optoelectronic properties can be finely tuned through the blending process as well as through IL selection and concentration, offering insights into the design of advanced materials for optoelectronic\u0026nbsp;applications.\u0026nbsp;\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003E\u0026nbsp;Controlling Local Order by Blending Conjugated Polymers with Ionic Liquids \u0026nbsp;\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":" Controlling Local Order by Blending Conjugated Polymers with Ionic Liquids  "}],"uid":"27707","created_gmt":"2025-01-08 13:49:17","changed_gmt":"2025-01-08 13:49:53","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-01-09T12:00:00-05:00","event_time_end":"2025-01-09T14:00:00-05:00","event_time_end_last":"2025-01-09T14:00:00-05:00","gmt_time_start":"2025-01-09 17:00:00","gmt_time_end":"2025-01-09 19:00:00","gmt_time_end_last":"2025-01-09 19:00:00","rrule":null,"timezone":"America\/New_York"},"location":"TEAMS","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"111531","name":"ms defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
