Introduction

Dr. Denis Fichou is a Research Director at CNRS (1st class), France, and a Full Professor at Nanyang Technological University (NTU), Singapore. He is the current Head of the "Organic Nanostructures and Semiconductors" laboratory that he founded in 2001 at Pierre et Marie Curie University, Paris. Following a first two-week visit in Singapore as early as 1978, D. Fichou came back to Singapore several times in the 80s and 90s to attend large conferences. He was invited to NTU for the first time in 2003 and has been a Visiting Professor at the School of Material Science & Engineering (MSE) up to 2012. He was in particular awarded a presidential Tcheng Tsang Man Chair for the period 2005-2008. From 2012 to 2015 he has been a Visiting Professor at the School of Physical & Mathematical Sciences (SPMS) and was appointed as a Full Professor in Chemistry and Material Science in 2016. Over his recent years at SPMS, D. Fichou established a new research laboratory focusing on "New Materials for Sustainable Energy" (Website: http://www.ntu.edu.sg/home/denisfichou/).

In the late 80s D. Fichou has pioneered the then-emerging field of "organic electronics". In particular he is the co-inventor of the first organic field-effect transistor (OFET) on a flexible substrate (Advanced Materials 1990) thus opening "the era of flexible electronics". Since then, he has been developing new organic semiconductors based on small pi-conjugated molecules, in particular the oligothiophenes family. Over the last 30 years he investigated the transport and optical properties of these organic materials in thin film and single crystal devices. Today his research is oriented towards the design of novel efficient hole-transport materials such as the quinoidal dipyranylidenes analogs for solar cells applications. He also focuses on the growth and transport properties of several types of organic single crystals that he investigates in various device configurations. Besides, he is also developing new oxide-based photoelectrochemical systems (notably WO3, MoO2, and Cu2O) for conversion of light, water splitting and energy storage. He has published over 200 articles in international journals such as Nature, Advanced Materials, ACS Nano, JACS, Angewandte Chemie, etc. Besides, he is the holder of 10 patents and the editor and author of several books including the successful Handbook of Oligo & Polythiophenes (Wiley-VCH, over 2.400 citations). Finally, his publications in academic journals have received a total of 11.300 citations (Google Scholar h-index=46).

Interfacial Engineering for Quantum‐Dot‐Sensitized Solar Cells

Chem. Asian J., 2016, 11, 1183-1193.

Chemistry - An Asian Journal

Quantum-dot-sensitized solar cells (QDSCs) are promising solar-energy- conversion devices, as low-cost alternatives to the prevailing photovoltaic technologies. Compared with molecular dyes, nanocrystalline quantum dot (QD) light absorbers exhibit higher molar extinction coefficients and a tunable photoresponse. However, the power- conversion efficiencies (PCEs) of QDSCs are generally below 9.5%, far behind their molecular sensitizer counterparts (up to 13%). These low PCEs have been attributed to a ...

Anti-ferromagnetic coupling in hybrid magnetic tunnel junctions mediated by monomolecular layers of α-sexithiophene

Appl. Phys. Lett., 2013, 103, 042417.

Applied Physics Letters

We report here on the magnetic coupling taking place between Fe3O4 and Co layers across an organic monolayer of α-sexithiophene (6T). The controlled growth of 6T ultrathin films on epitaxial Fe3O4 surfaces allows to prepare highly homogeneous insulating layers with thicknesses in the range 0.5–2.0 monolayers (ML). A combined study using vibrating sample magnetometry and polarized neutron reflectivity reveals that hybrid Fe3O4/6T/Co tunnel junctions show different magnetic couplings depending on the 6T thickness. In particular, ...

New journal of chemistry

Adsorption of two trimethylsilylacetylene (TMSA) derivatives bearing linear alkyl chains of different lengths has been studied at the n-tetradecane/Au (111) interface. The lying or standing orientation of TMSA compounds on the gold surface shows that adsorption is not only controlled by the chemical reactivity

Synthesis and 2D self-assembly at the liquid–solid interface of novel H-bonding linear π-conjugated oligomers terminated by uracil and melamine units

New J. Chem., 2014, 38, 2407-2413.

New Journal of Chemistry

We report here on the synthesis and 2D self-assembly of novel H-bonding linear π- conjugated oligomers terminated at both ends by either two uracil moieties (compound GR1) or by two melamine groups (compounds GR2 and GR3). The bis (uracil) GR1 compound was prepared by Sonogashira coupling of an ethynyluracil with a dihalobenzene and characterized spectroscopically. The synthesis of GR2 and GR3 was performed by Suzuki coupling of the dihalogenated benzene derivatives leading to the respective bisadducts ...

We describe here an efficient synthetic route toward novel organocobalt complexes [(η4-C4 (nT) 4Co (η5-C5H5)] with n= 1, 2, 3 thiophene rings. The key step is the use of CpCo (CO)(DMFU), with DMFU= dimethylfumarate, engaged in a [2+ 2] cycloaddition under microwave conditions. Taking advantage of the good solubility
