Journal ArticleDOI
Effect of interfaces on the alignment of a discotic liquid-crystalline phthalocyanine.
Vinciane De Cupere,Julien Tant,Pascal Viville,Roberto Lazzaroni,Wojciech Osikowicz,William R. Salaneck,Yves Geerts +6 more
TL;DR: The influence of the nature and number of solid interfaces on the alignment of the columns in a semiconducting discotic liquid crystal is dealt with.
Journal ArticleDOI
Liquid Crystalline Metal-Free Phthalocyanines Designed for Charge and Exciton Transport
Julien Tant,Yves Geerts,Matthias Lehmann,Vinciane De Cupere,Gaël Zucchi,Bo W. Laursen,Thomas Bjørnholm,Vincent Lemaur,Valérie Marcq,Anick Burquel,Emmanuelle Hennebicq,Fabrice Gardebien,Pascal Viville,David Beljonne,Roberto Lazzaroni,Jérôme Cornil +15 more
TL;DR: Two metal-free phthalocyanines with different branched aliphatic chains on the gram scale are synthesized to allow for a full characterization of their solid-state properties and self-organize in liquid crystalline mesophases.
Journal ArticleDOI
Discotic liquid crystals as electron carrier materials
Olivier Roussel,Gaël Kestemont,Julien Tant,Véronique de Halleux,Rafael Gómez Aspe,Jérémy Levin,Adrienne Remacle,Iona Raluca Gearba,Dimitri A. Ivanov,Matthias Lehmann,Yves Geerts +10 more
TL;DR: A series of five new hexaalkylthiohexaazatriphenylenes 2a-e has been synthesized and their thermotropic behavior has been investigated.
Journal ArticleDOI
Charge recombination in distributed heterostructures of semiconductor discotic and polymeric materials.
Jenny Clark,Robert Archer,Tim Redding,Clare Foden,Julien Tant,Yves Geerts,Richard H. Friend,Carlos Silva +7 more
TL;DR: In this article, an emissive exciplex formed between an electron-accepting discotic material (hexaazatrinaphthylene or HATNA-SC12) and a hole accepting conjugated polymer {poly[9,9- dioctylfluorene-co-N-(4-butylphenyl)diphenylamine] or TFB}.
Journal ArticleDOI
Large electronic bandwidth in solution-processable pyrene crystals: The role of close-packed crystal structure
Françoise Provencher,Nicolas Bérubé,Jean-Frederic Laprade,Gabrielle Simard,Julien Tant,Véronique de Halleux,Yves Geerts,Carlos Silva,Michel Côté +8 more
TL;DR: This work examines the interdependence of structural and electronic properties of two substituted pyrene crystals by means of combined spectroscopic probes and density-functional theory calculations and finds that photophysical defects, ascribed to excimer-like states, point to the importance of localized trap states.
