    Research Interests
    1. Printed/Flexible/Stretchable/Sustainable Organic Electronics. A rapidly advancing area of technological and basic research is “flexible electronics”-- in particular, organic thin film transistors (OTFTs) based on organic small molecule and polymeric semiconductor, dielectric and conductor materials. OTFTs based on such advanced components have been proposed for several uses, such as flexible/bendable displays for commercial and military applications (rolling maps, soldier electronic textile), radio-frequency identification tags, smart cards, and sensors. The main goal of the present research is to design, synthesize, and characterize novel organic (semi)conductors and dielectrics for the above applications that will compete with the current inorganic technology based on silicon TFTs as well as create new TFT platforms for novel applications. A key aspect of this project is to enhance sustainability and reduce the carbon footprint for the preparation of electronic materials and in the fabrication of electronic devices.
    2. Organic and Thin-Film Photovoltaic Cells. Photovoltaic (PV) cells based on organic photoactive thin-film materials offer the promise of large-scale manufacture for producing cheap solar electricity with low-cost, light-weight, non-toxic, and earth-abundant materials. A major step to enable this technology will come from the rational engineering of photoactive polymeric materials with tailored electronic structures and orbital energetics to optimize: light absorption, exciton splitting, active layer charge transport, interfaces for photocurrent collection, and film processing. Furthermore, an essential goal is to achieve ductile solar cells and modules for integration with flexible and stretchable devices.
    3. Transparent/Solution Processable Metal Oxide (MO) Electronics. Transparent electronics is a technology aiming at producing “invisible” electronic circuits and devices. Applications include consumer electronics and transportation. For example, automobile windshields could transmit visual information. Glass in almost any setting could also double as an electronic device, possibly improving security systems or transparent displays. As for the conventional Si/GaAs electronics, the basic circuit structure is based on the thin-film transistor. However, the transistor building block materials, the semiconductor, the dielectric, and the conductor, must now be transparent in the visible. Therefore, the main scientific goal of this technology is to discover, understand, and implement transparent high-performance materials and their high-yield implementation in transistor/circuit structures. Furthermore, if these materials can be solution-processed, a venue to high-performance, transparent, and inexpensive electronic circuits and devices can be opened.
    4. Polymers for Energy Storage. The rapidly and globally increasing demand for energy results in challenges concerning not only the conversion but also the storage of electrical energy. Batteries, fuel cells, and supercapacitors have been the focus of considerable research due to their key role regarding “portable energy”, as well as the rapid development of active radio-frequency identification (aRFID) tags, integrated-circuit smart cards, mobile sensor systems, smart clothes, electric vehicles, and grid-level energy storage. In all these key technologies, the relatively poor battery performance of existing energy storage systems represents the major bottleneck. In this area our goals are to develop unconventional materials, particularly organic polymers, to enhance battery performance and enable implementation in light/flexible devices.
    5. SERS Sensors. The identification and quantitative determination of ultra-low concentrations of chemical and biological molecules is relevant in several fields including medical diagnostic, environmental science, and homeland security. Conventional routes to analyte detection rely on optical, electrochemical, electronic, and gravimetric methodologies. Surface enhanced Raman spectroscopy (SERS) is an ideal surface-sensitive technique allowing non-destructive molecular analysis with high sensitivity and selectivity approaching single-to-few molecules detection. Here we are using organic semiconductors as SERS-active platforms and investigate their integration into different sensor architectures.
    6. Organic Mixed Ionic-Electronic Conductors and Bioelectronics. Organic mixed ionic–electronic conductors (OMIECs) are materials that conduct both ions and electronic charge carriers (electrons and/or holes) and are the key components of organic electrochemical transistors (OECTs). These devices are transistors operating at very low voltage and exhibit large transconductance (signal amplification). Since ions are need for their operation and because biology uses ions for signaling, OECTs are ideal candidates to interface electronic devices with biology. Thus, in this project we design and synthesize new OMIEC materials, investigated details of their charge transport properties, fabricate and invent new OECT architectures and we apply them for new type of OECT circuits embedding driving, sensor and neuromorphic functions.
    7. N-Doping of Organic Semiconductors. The doping of inorganic materials has been instrumental in the progress of the semiconductor industry. For organics (soft matter), several strategies have yielded doped π-electron solids with greatly enhanced opto-electronic properties as well as novel materials, physical phenomena, and device concepts, supporting the commercialization of PEDOT:PSS, OLEDs, and other materials technologies. However, these advances were largely enabled by p-doped (hole transporting) materials, while useful n-doped (electron-transporting) materials have been limited in chemical accessibility, doping efficiency, electron mobility and conductivity. This limits their introduction in several opto-electronic devices where both p-type and n-type (semi)conductors are required. Research goals in this topic include to explore new organic semiconductors, dopants, and catalysts to elucidate the mechanism of the catalytic n-doping process, expand the scope to other type of catalysts and integrate catalyzed-doped materials into devices.
