The official Barcelona anthem is the " Cant del Barça", written by Jaume Picas and Josep Maria Espinàs. It is the fourth-most valuable sports team in the world, worth $4.76 billion, and the world's fourth richest football club in terms of revenue, with an annual turnover of €582.1 million. Unlike many other football clubs, the supporters own and operate Barcelona. Further, this is the first time that DB-TTF thin films of the α-polymorph are reported.Futbol Club Barcelona ( Catalan pronunciation: ( listen)), commonly referred to as Barcelona and colloquially known as Barça ( ), is a professional football club based in Barcelona, Catalonia, Spain, that competes in La Liga, the top flight of Spanish football.įounded in 1899 by a group of Swiss, Catalan, German, and English footballers led by Joan Gamper, the club has become a symbol of Catalan culture and Catalanism, hence the motto "Més que un club" ( "More than a club"). It is demonstrated that the control of the thermodynamics and kinetics of the crystallization process is key for the device performance optimization. Here, it is demonstrated that varying the deposition parameters (i.e., speed and temperature) or the solution formulation (i.e., semiconductor/binder polymer ratio) is possible to control the film morphology and semiconductor polymorphism and, hence, the different intermolecular interactions. In this work, the preparation of thin films is reported based on blends of the organic semiconductor dibenzo-tetrathiafulvalene (DB-TTF) and polystyrene by a solution shearing technique compatible with upscaling. To achieve a high device-to-device reproducibility it is essential to control the morphology and polymorphism of the active layer for OFET application. The device reproducibility is one of the principal weak points of organic electronics for further commercialization. Despite the high mobility achieved so far with organic molecules, in order to progress in the field it is crucial to find techniques to process them from solution. During the last decades, small molecule organic semiconductors have been successfully used as active layer in organic field-effect transistors (OFETs).
