INTRODUCTION：
Professor Attilio Golemme was born in Cosenza (Italy) in 1959. He received his first degree (Laurea) in Chemistry from the University of Calabria in 1983 and his Ph.D. in Chemical Physics from Kent State University in 1987. From 1986 to 1998 he was a Researcher at the Chemistry Department of the University of Calabria. Since 1998 he is an Associate Professor of Physical Chemistry at the University of Calabria, Faculty of Science. In 2008, he received Fulbright Fellowship to conduct research at the Georgia Institute of Technology. He has served on the committee for several international scientific meetings in the field of liquid crystal, organic optics, and optoelectronics, and is a referee for many scientific journals. He has authored/co-authored more than 80 publications on refereed journals, patents, and book chapters.
ABSTRACT：
In recent years, the development of organic materials for optoelectronics and photonics has been continuously progressing, driven by the prospect of manufacturing flexible, low-cost devices with tailorable properties for specific applications. In this seminar, the development of different classes of organic semiconductors will be described.
A new class of photoconductors will be presented, where a single low molecular mass molecule exhibits all the functions necessary for photorefractive behaviour: photogeneration, transport and trapping of charges, and an electric field dependent refractive index. The active species are cyclometallated molecules which contain a Palladium (II) or Platinum (II) centre bonded in a square planar geometry. The charge generation process in such materials was investigated and results show interesting potential for other applications including photovoltaics.
We have also recently investigated multifunctional optically active methacrylic polymers bearing three distinct functional groups (i.e. azoaromatic, carbazole and a chiral group of one single configuration) directly linked to the side chain. These materials are characterized by conformations with a prevailing chirality, optically switchable. Room-temperature photorefractivity without pre-poling was demonstrated in polymers and copolymers with a glass transition temperature well above 100 °C.
In addition, a few examples illustrating the functional role (for charge transport and refractive index modulation) of the spontaneous supramolecular organization typical of mesophases will be discussed.
