The biennial Cecil
L. Brown Lectureship was established by NJ-ACS in 1969 to bring a
distinguished chemist to a local university in the North Jersey
area. Past recipients of this lectureship include seven Nobel
laureates as well as many other towering figures in chemistry.

The 2011 Distinguished Lecturer is
Professor Louis Brus,
Institute Professor at Columbia University.
has a BA from Rice University and a PhD from
Columbia University, both in Chemical Physics. As a Lieutenant in
the U. S. Navy, he worked in the solid state and chemistry divisions
of the Naval Research Laboratory in Washington DC. In 1973 he joined
the research area of Bell Laboratories in Murray Hill, NJ, where
he became Distinguished Member of Technical Staff. He returned to
Columbia in 1996, where he is now S. L. Mitchill Professor of
Chemistry. He is a member of the US National Academy of Sciences,
and in 1998 was the Chairman of the Board of Trustees of the Gordon
Conferences. He was originally trained in gas phase spectroscopy
and kinetics. In the 1980s he explored basic ideas and colloidal
methods for semiconductor nanocrystals (Qdots) that exhibit quantum
size effects. His present interests include carbon nanotubes and
graphene, chemical applications of local electromagnetic fields,
and solar energy nanoscience. He has received the APS Langmuir
Prize, the ACS Chemistry of Materials Prize, the OSA Wood Prize,
the inaugural Kavli Prize in Nanoscience, and the NAS Prize in the
Chemical Sciences. For further details of Professor

“Electron Correlation in Carbon Nanotubes and Graphene”
by Professor Louis Brus
We explore the fundamental nature and dynamics of excited electronic
states in graphitic carbon materials. In semiconducting carbon
nanotubes, near-infrared two photon luminescence excitation spectra
quantitatively reveal very-strongly-bound exciton excited states.
Electron-electron interactions are compared among CdSe nanocrystals,
graphene, and carbon nanotubes. The independent contributions of
screening and dimensionality are analyzed. Electronic and vibrational
degrees of freedom are significantly coupled in graphene. The
metallic versus molecular nature of single sheet graphene is strongly
affected by charge transfer doping by adsorbed molecular species.
Asymmetric doping in bilayer graphene can open a band gap, as
revealed by the Raman spectra. Optical absorption bleaching and
Raman Fano lineshapes are observed in few layer graphenes very
highly doped by adsorbed alkalis.
There will be a reception following the lecture.

Cecil L. Brown
This lectureship was named after Cecil L. Brown, who spent his
entire professional career at Esso (which later became Exxon) and
chaired NJ-ACS as well as the Petroleum Division of national ACS
in the 1950s. He was also the Chairman of the Esso Research Contributions
and Research Grants Committee. During his chairmanship some 400
grants were made to 60 colleges and universities. As an administrative
member of the Esso Education Foundation, he helped carry out a
special $1.5 million program for the improvement of science and
engineering teaching in New Jersey. He was a strong a proponent of
having world-class chemists visit and work with students. Through
the Cecil L. Brown Lecture, it is fitting that his name continues
to be associated with excellence in chemical education in our area.
