Patent number: 8143091Abstract: A method realizes a thin film organic electronic device integrated on a substrate and includes an organic material layer and an organic thin film transistor or OTFT transistor. The method comprises: depositing the organic material layer on the substrate, the organic material layer being a conductive organic polymer; patterning by a soft-lithographic procedure the organic material layer to create a reduced portion in order to make a channel area of the OTFT transistor; masking the organic material layer by covering with a cover mask a source area and a drain area of the OTFT transistor; irradiating by ultraviolet radiation to deactivate exposed portions of the organic material layer defining the source area, the drain area and the channel area; depositing on the organic material layer a semiconductor layer; and creating on the semiconductor layer a gate area of the OTFT transistor.Type: GrantFiled: November 24, 2009Date of Patent: March 27, 2012Assignee: STMicroelectronics S.r.l.Inventors: Giovanna Salzillo, Maria Grazia Maglione, Anna Morra, Luigi Occhipinti

Patent number: 8003228Abstract: New, highly photoluminescent compounds are described having structural formula (I) wherein: R1, R2, R3, R4, independently from each other, represent H; alkyl, alkenyl; aryl; —(CH2CH2—O)n—CH3. These compounds are highly photoluminescent and have high quantum yield; they have optimal plasticity characteristics and optimal miscibility with other amorphous polymers; they lead to the formation of thin, stable and uniform layers of photoluminescent material, obtainable by simple techniques of deposition from solution. A simple and high yield process is described for obtaining the aforesaid compounds. In addition, the use of the compounds of formula (I) and their polymer derivatives is described in the preparation of electroluminescent devices, for example LEDs.Type: GrantFiled: June 26, 2008Date of Patent: August 23, 2011Assignee: STMicroelectronics S.r.l.Inventors: Giovanna Salzillo, Antonio Roviello, Giuseppina Roviello, Giuseppe Russo
