synthesis and characterisation of small molecules for electronic and optical applications, including
transition metal complexes, lanthanide complexes and organic molecules. In addition to chemical
synthesis, he has extensive experience in molecular characterisation by electrochemistry,
UV/Vis/NIR spectroscopy, spectroelectrochemistry, emission spectroscopy and computational
methods. The group also carries out initial in-house characterisation of materials and devices
including solar cells, FETs and luminescent materials. Motivation for this work has included synthesis
and characterisation of new dyes for solar cells, small-molecules for conducting materials,
luminescent materials for solar concentrators, molecular magnetic
materials and ion sensors.

Synthesis of organophosphorous-based pi-conjugated systems. 1. design and synthesis of
organophosphorus extended pi-conjugated materials (small molecules, polymers) which can be used
for diverse applications such as organic light emitting diodes (OLED?s), including white OLED-s
(WOLED-s), or sensing 1. The supramolecular organization of conjugated systems in the solid state is
a key point for the optimization of optoelectronic devices. 2. The second one is to modify pi-systems
such as helicenes, which are key chiral derivatives, with phosphole moieties. 3. the synthesis and
study of chiral systems including transition-metal containing systems. 4. Using the coordination
chemistry of phosphole-pyridine ligands allows for the development of transition metal molecular
clips which are well suited to organize ditopic conjugated systems into discrete or polymeric
metallocyclophanes. 5. TD-DFT calculations as a tool to have more insight into our systems.

Most polymers, or plastics, are electrical insulators. However there is one class of polymers, known
as 'conjugated' polymers which can conduct electricity. These materials are semiconductors, and
open new directions in optoelectronics. They combine novel semiconducting electronic properties
with the processing flexibility of polymers. When a voltage is applied to them, they emit light,
providing an important new display technology that could give flat and even flexible displays.
Semiconducting polymers can be used to make field effect transistors, solar cells, and even lasers. In
the polymer optoelectronics group we seek to understand the physics of these remarkable materials
and devices, with the aim of improving them. The research has both fundamental and applied
aspects, and the main activities are: - optical amplifiers - wavelength scale microstructure - new
materials - charge transport in LEDs - understanding the light emission process.
