    Dr. George Pistolis is Researcher Director of the Electronic Spectroscopy Laboratory at the National Center for Scientific Research "Demokritos" in Aghia Paraskevi, Greece, the largest state-owned research organization in the country. He graduated from the National and Kapodistrian University of Athens, obtaining the Degree of Chemistry in 1986. After two years of military service (1986-1988) he entered the Graduate Programme of the University of Athens in collaboration with the Institute of Physical Chemistry (IPC) of the National Centre for Scientific Research "Demokritos" (N.S.C.R. "D"). He obtained his PhD in photochromic supramolecular materials in 1994. In 1995 he obtained a post-doctoral position at the Institute of Physical Chemistry (IPC), of N.S.C.R. "Demokritos" to work with Dr. A. Malliaris in the field of spectroscopy in organized molecular systems. He has been a frequent Visiting Scientist at the Institute of Synthetic Polymer Materials of Russian Academy of Sciences in Moscow during the period of 1999-2002. In addition to his research interests, he has worked as Assistant Professor in the Department of Materials Science of the University of Ioannina, Greece, for three years (2000-2003) teaching General Chemistry (class and lab) and Physical Chemistry. In 2003 he joined the Institute of Physical Chemistry (IPC), of N.S.C.R. "Demokritos" as a Researcher C. In 2006 he became Senior Researcher B and in 2011 he was promoted to Research Director.


    Dr. George Pistolis leads a multidisciplinary research program devoted to the Molecular Engineering of Photo-functional Self-Assembled Nanosystems. More specifically his research focuses on the design, synthesis, characterization and in-depth spectroscopy of functional dyes and their programmable self-assembly into well-defined photo-(re)active nanoarchitectures with tailored properties for potential applications in lighting, solar energy conversion, electronics – photonics, molecular sensing and machinery. 


    Over the past decade and more, our group has been extensively studying various aspects of supramolecular architectures - spanning from simple inclusion compounds to complex self –assembled nanostructures -  such as,


    • · Guest stability and Dynamics in Nanocavities

    •  Stereoselective host-guest interactions

    • Structure, stability and dynamics of non-covalently bonded nanotubes and supramolecular polymers based mainly on cyclodextrins

    • Excited-state kinetics and thermodynamics of reversible isomerizations that can lead to autonomous   mechanical response at the molecular level

    • Fluorescent sensors for the signaling of molecular and macromolecular recognition events

    • Structural features and control release properties of self-assembled nanosystems with fluorescent “on-off” switches

    • Photophysics, dynamics and energy transfer phenomena in blue-emitting linear and dendronized photonic polymers

    • Color tunability engineering in Organic Light Emitting Diodes and Optical Lithography


    After obtaining a sufficient expertise on the aforementioned thematic areas, the new activities of our group focus on the design, supramolecular synthesis, characterization and comprehensive spectroscopy of cleverly engineered self-assembled complex nanoarchitectures capable of exploiting light for tuning and tailoring the properties of advanced materials. More specifically, we are interested in constructing intensely absorbing/emitting metallosupramolecular host nanoarchitectures with size-adjustable nanoporous cavities capable of accommodating a large variety of semiconducting materials. We further intend to achieve precise control over the spatial topology and the energy levels of the interacting dipoles in the above multichromophoric arrays and to provide new insights into beneficial pathways for harvesting, transferring, (up)-converting and funnelling electronic energy in the condensed phase for multifunctional applications including, accumulation and tuning in photo(electro)-luminescence, light-harvesting and solar energy conversion, organic electronics and photovoltaics, photomechanical responses and molecular sensing.

    Coordination–driven supramolecular synthesis of a rhomboid cavitand (12)2 - comprising two distinct BODIPY based dyes  - and its inclusion complex with 4SPy via ionic self-assembly


     Crystal structure of the inclusion complex 4SPyÌ(12)2


    The main methodologies and techniques involved in our research comprise:

    · Design and synthesis of photomolecular building blocks and their subsequent directed supramolecular synthesis – via combinations of selected self-assembly protocols - into well-defined photo-functional nanoarchitectures. Verification of the structures is made by means of structural (multinuclear NMR & 2D NMR, ESI-MS, X-ray crystallography, SAXS, STM, AFM) and electronic/optical (UV/Vis/NIR absorption and fluorescence) characterization techniques.


    · Electronic spectroscopy methods, both steady-state and time-resolved, to study photophysical and photochemical processes, such as kinetics and thermodynamics of energy/electron transfer phenomena – photomechanical conversions, rotational dynamics etc. We perform research on subnanosecond to millisecond time scales in NCSR Demokritos. Ultrafast measurements (femto-to-picoseconds) are investigated in collaboration with Dept. of Physics, University of Patras and with laboratories in Europe.
