We introduce a synthetic route to \ngraphenes that is based upon the cyclodehydrogenation \n(\u201cgraphitization\u201d) of well-defined dendritic (3D) polyphenylene \nprecursors. This approach is superior to physical methods of graphene \nformation, such as chemical vapour deposition or exfoliation, in terms of \nits size and shape control, structural perfection and processability \n(solution, melt and even gas phase). The most convincing case is the \nsynthesis of graphene nanoribbons under surface immobilization and \nin-situ control by scanning tunnelling microscopy.\u003C\/p\u003E\n\u003Cp\u003EColumnar superstructures assembled from these nanographene discs \nserve as charge transport channels in electronic devices. Field-effect \ntransistors (FETs), solar cells and sensors are described as examples.\u003C\/p\u003E\n\u003Cp\u003EUpon pyrolysis in confining geometries or carbomesophases, the \nabove carbon-rich 2D- and 3D- macromolecules transform into \nunprecedented carbon materials and their carbon-metal nanocomposites. \nExciting applications are shown for energy technologies such as battery \ncells and fuel cells. In the latter case, nitrogen-containing graphenes \nserve as catalysts for oxygen reduction, which have an efficiency that is superior to \nthat of platinum.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESpeaker\u0027s Bio:\u0026nbsp;\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EProfessor Klaus M\u00fcllen obtained a Diplom-Chemiker degree at the University\n of Cologne in 1969 after working with Professor E. Vogel. His Ph.D. degree\n was granted by the University of Basel, Switzerland, in 1972 where he \nundertook research with Professor F. Gerson on twisted pi-systems and \nEPR spectroscopic properties of the corresponding radical anions. In \n1972, he joined the group of Professor J.F.M. Oth at the Swiss Federal \nInstitute of Technology in Z\u00fcrich where he worked in the field of \ndynamic NMR spectroscopy and electrochemistry. He received his \nhabilitation from the ETH Z\u00fcrich in 1977 and was appointed Privatdozent.\n In 1979, he became a professor in the Department of Organic Chemistry, \nUniversity of Cologne, and accepted an offer of a chair in organic chemistry at the University of Mainz in 1983. He received a call to the \nUniversity of G\u00f6ttingen in 1988. Since 1989, he has worked as a director and \nscientific member at the Max Planck Institute for Polymer Research. His \nresearch interests are in the field of preparative macro-and \nsupramolecular chemistry. His group has succeeded at including the \nsynthesis and characterization of previously inaccessible large \npolycyclic aromatics.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThe Center for Organic Photonics and Electronics Distinguished Lecture Series welcomes Professor \nKlaus M\u00fcllen, a director at the Max-Planck Institute for Polymer \nResearch.\u003C\/p\u003E\u003Cp\u003EFor more information, click \u003Ca href=\u0022http:\/\/www.cope.gatech.edu\/news\/lecture\/mullen.php\u0022\u003Ehere\u003C\/a\u003E.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"The Center for Organic Photonics and Electronics Distinguished Lecture Series welcomes Professor Klaus M\u00fcllen, a director at the Max-Planck Institute for Polymer Research."}],"uid":"27445","created_gmt":"2011-03-01 09:38:29","changed_gmt":"2016-10-08 01:54:26","author":"Amelia Pavlik","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2011-04-01T17:00:00-04:00","event_time_end":"2011-04-01T18:00:00-04:00","event_time_end_last":"2011-04-01T18:00:00-04:00","gmt_time_start":"2011-04-01 21:00:00","gmt_time_end":"2011-04-01 22:00:00","gmt_time_end_last":"2011-04-01 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.cope.gatech.edu\/","title":"COPE"}],"groups":[{"id":"1182","name":"General"}],"categories":[],"keywords":[{"id":"10797","name":"center for organic photonics and electronics"},{"id":"12180","name":"Klaus Mullen"},{"id":"6116","name":"Lecture Series"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:gth625a@mail.gatech.edu\u0022\u003EJason Martin\u003C\/a\u003E\u003Cbr \/\u003ECenter for Organic Photonics and Electronics\u003Cbr \/\u003E404-385-3138\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
