A report on research and other academic activities
Philosophy and Mission:
Life on Earth begins with the self-organization of molecules. No life would be possible
without the self-assembly of lipids into bilayers within the cell membrane. Numerous
biological supramolecular structures, e.g., the spontaneous formation of the double helix
3
of nucleic acids, collagen, microtubules, ribosomes, multisubunit enzymes, etc., result
from self-assembly of organic molecules. In materials science, non-covalent interactions
have been used to obtain well-defined self-assembled architectures in neat systems as
well as in solvents. Liquid crystals (LCs) belong to one of such systems. Supramolecular
interactions such as van der Waals forces, dipolar or quadrupolar interactions, charge-
transfer interactions and hydrogen bonding play a crucial role in the formation of LCs
and in the determination of their mesomorphic properties. Liquid crystalline state - the
fascinating, intriguing, beautiful, mysterious, delicate fourth state of matter, is an
intermediate state between the solid and the liquid. Liquid crystals are unique
nanostructures with remarkable electronic and optoelectronic properties.
The research in my group is concerned with the design and synthesis of various
liquid crystalline materials. I am interested in understanding the structure-property
relationship in these intriguing self-assembling supramolecular architectures. Our present
objectives are: (a) design and synthesis of novel liquid crystalline materials; (b)
development of new synthetic routes to the synthesis of LCs; (c) search for new reagents
for the synthesis of LCs; (d) synthesis and characterization of various zero-, one- and
two-dimensional metallic, semiconducting and carbon nanoparticles; (e) incorporation of
nanoparticles in the supramolecular order of LCs to hybridize their properties; (f)
physical studies on liquid crystals and nanoparticles dispersed liquid crystalline systems
and their application in devices like photovoltaic solar cells, light emitting diodes,
sensors, thin-film transistors, etc.
Brief outline of my research career:
I started my research career in 1981 as a Ph.D. student with Professor A.B. Ray at the
Banaras Hindu University, Varanasi. After completing my Ph.D. in 1986, I worked with
Dr. Sukh Dev at Malti Chem Research Centre, Vadodara for about two and half years and
then moved to the Hebrew University of Jerusalem, Israel for a post-doctoral research
with Professor E. Glotter followed by the post-doctoral work with Professor E. Keinan at
Technion, Israel Institute of Technology, Israel. I was a post-doctoral fellow at the
Scripps Research Institute, La Jolla, USA during 1992-1994 with Professor Keinan
followed by at the University of Mainz, Germany with Professor H. Ringsdorf during
1994-1995. I joined the Centre for Liquid Crystal Research, Bangalore as a Scientist to
start a new Chemistry lab in September 1995. In December 2002 I joined the Raman
Research Institute (RRI) as a Senior Associate Professor and become Full Professor in
2007. In 2015, I was given Professor P2 (Senior Professor) status. I have served as a
member of Library committee, Coordinator, Soft Condensed Matter Group, Chair,
Overseas Committee and Chair, Committee for Administration, RRI. I was a visiting
Research Professor at the Navel Research Laboratory, Washington DC during 1999-
2000, at the National Dong Hwa University, Taiwan during 2008-2009 and at the Trinity
College, Dublin, Ireland during 2012-2013. I have also visited many other countries like,
U.K., France, Japan, Slovenia, Italy, Korea, Malaysia, China and Poland to deliver
lectures and to attend conferences (Appendix I).
A summary of Research Publications and citations:
I have published over 200 research papers in more than 70 different international
journals. Most of my papers have been published in highly reputed international journals
4
like Nature, Angewandte Chemie Int. Ed., Advanced Materials, Journal of American
Chemical Society, Journal of Organic Chemistry, Chemistry of Materials, Journal of
Chemical Society, Chemical Communications, RSC adv., Journal of Materials Chemistry,
Soft Matter, Phys. Rev. Lett., Particles, Langmuir, J. Phys. Chem.B, Tetrahedron Letters,
Tetrahedron, Synthesis and Liquid Crystals (Appendix II - IV). Professor Percec, the
editor of the book series "Liquid Crystals" published by CRC Press has invited me to
write a book on “Chemistry of Discotic Liquid Crystals”. This is the first dedicated book
on this topic. The LC Book series has excellent reputation in the field of soft condensed
matter and was under the editorship of the eminent Professors George Gray and John
Goodby. I was also invited by the Cambridge University Press to write a book on Liquid
Crystal Dimers. I have written several chapters for highly reputed books in the field of
liquid crystals on invitation. The editors of several journals like, Nature Asia Materials,
Nature Polymer J., Chemical Society Reviews, Israel J. Chem., Liquid Crystals and Phase
Transitions have invited me to write review articles for their journals. My research papers
have already been cited more than 4000 times (the citations of some paper are given in
Appendix II) and several publications have been amongst the most cited and accessed
papers. The Royal Society of Chemistry invited me for a celebratory ‘most cited’ dinner
at the ACS National Meeting in Washington. This awards dinner hosted the most cited
authors from two flagship journals, Chem Comm and Chem Soc Rev, for the years 2006
and 2007. A few patents have also been granted to me. The Royal Society of Chemistry,
London awarded me the journals grant for international authors in 2001. In addition to
citations in research papers, my work has also been referred to in books. For instance, the
importance of new reagents developed by me for the synthesis of symmetrical,
unsymmetrical and functionalised triphenylenes has been discussed by G. Lessene in the
book “Modern Arene Chemistry, Didier Astrue (Ed.), Wiley-VCH, Weinheim, 2002,
page 501. Several researchers all over the world are using these reagents for the improved
synthesis of triphenylene derivatives. The International Liquid Crystal Society has
presented me the inaugural LG Philips Display Mid-Career Award at the International
Liquid Crystal Conference held at Jeju, Korea on July 2, 2008. The Science Foundation
of Ireland awarded me the prestigious E.T.S. Walton Visiting Professor award in 2012.
Reviewing of manuscripts, research proposals and Ph.D thesis :
I am a Reviewer for more than 70 different international journals like, ACS Nano, Chem.
Rev., Angew. Chem. Int. Ed., Adv. Mater., JACS, ACS Applied Materials, Nano Lett.,
Org. Lett., Macromolecules, Chem. Commun., J. Mater. Chem., Soft Matter., RSC Adv.,
Tet. Lett., Chem. Mater., J. Phys. Chem., Euro Phys. Lett., J. Phys. Org. Chem., J. Appl.
Poly. Sci., J. Porphyrins Phthalocyanines, Syn. Metal, Phase. Trans., Liq. Cryst., Mol.
Cryst. Liq. Cryst., Syn. Lett., Beilstein J.O.C., Bulletin of Materials Science, J. Mol. Liq.,
J. Renewable Sustainable Energy, etc. and have reviewed more than 200 research papers.
I have reviewed a number of research proposals submitted to various National and
International funding agencies. The Department of Information Technology (DIT),
Government of India, has appointed me a member of several research committees. I have
also chaired a DIT committee. I have examined about 40 Ph.D. theses of different Indian
universities and conducted their viva-voce examination.
