Organic Materials

Organic materials π-conjugated with photo- and electroactive properties have a crucial role in field of organic electronics including applications such as organic solar cells (OSC), organic light emitting diodes (OLEDs), organic field effect transistors (OFETs), electrochromic devices, as well as biological applications such as biosensors and fluorescent probes for bio-imaging.

The focus of this research field concerns synthesis and characterization of new organic materials π-conjugated, with physicochemical properties attractive for application in optoelectronic.

Specific research topics are:

  1. Organic Materials π-conjugated for Electrochromic Application
  2. Synthesis and characterization of organic dyes as sensitizer for solar cells
  3. Synthesis and characterization of new organic pigments of natural origin based on the hydrogen bond
  4. Development of new organometallic methodologies for obtaining poly(arylenes) through a “chain growth mechanism”
  5. Synthesis of holt transporters for Perovskite solar cells

Organic Materials π-conjugated for Electrochromic Application

The main goal of this research line is to synthetize new organic compounds able change colour upon multiple oxidation and reduction processes. Electrochromic properties have been proved useful in the rear-view mirrors, electronic paper, energy saving smart window, and high contrast displays.

 

Synthesis and characterization of organic dyes as sensitizer for solar cell.

Dye-sensitized solar cells (DSSCs ) have attracted significant attention as potential low-cost replacements to silicon-based photovoltaic technology. High-performance sensitizers capable of wide-band spectral capture are recognized to be a promising strategy for improving the cost-efficiency of the DSSCs. In this perspective, have been designed and synthetized dyes able to convert the convert incident solar energy into electrical energy with high efficiency.

 

Synthesis and characterization of new organic pigments of natural origin based on the hydrogen bond

The main goal of this research line is to produce high-performance electronics (organic thin film transistors, OTFTs and circuits) that are fully biodegradable in a controllable manner when their life cycle is considered over. Within this line of research are investigated innovative synthetic approaches to epindolidione synthesis and some of its derivatives, materials that are used in organic field effect transistors (OFET) that are both highly efficient and biodegradable at the end of their lifecycle.

 

Development of new organometallic methodologies for obtaining poly(arylenes) through a “chain growth mechanism”

Conjugated polymers are the active materials of a wide number of smart devices. In this perspective, the availability of “sharp” synthetic tools for the controlled obtainment of conjugated organic polymers is a truly pressing issue since polymer-based device performancesis strongly affected by molecular weight, dispersity and regularity. In this perspective, our efforts are directed to the study of C-C coupling polymerisation reactions of suitable AB-type monomers via a chain-growth mechanism ensuring the necessary control over the molecular weights and polydispersities to the target materials.

 

Synthesis of hole transporters for Perovskite solar cells

Since the emergence of Perovskite Solar Cells (PSC) as highly promising photovoltaics, a great effort has been devoted to develop innovative and more efficient materials specifically designed for this architecture. Concerning Hole Transporting Material (HTM) for PSCs, the high synthesis cost of Spiro-OMeTAD and its low charge-carrier mobility jeopardize its commercial-scale application. Our work is devoted to the synthetic engineering of the photoelectrical properties of organic molecules as the way to find new suitable HTM candidates for high-performance PSCs.
