Current members of the Eisenberg group include (from left) Mesfin Janka, Young-A Lee, Tom Hackett, the Boss (or so he
thinks), Thad Wadas, Soma
Chakraborty, and Quanming Wang.
The Eisenberg group is engaged in a number of projects involving
organometallic and metal complex chemistry of the platinum group
elements. The organometallic chemistry focuses on reactions related to
catalysis and the design of new catalytically active complexes. In this
context, reactions with molecular hydrogen such as hydrogenation,
oxidative addition and hydroformylation are fundamentally interesting and
practically important. Research on these reactions in the Eisenberg
group has employed parahydrogen induced polarization (PHIP) as a means of
investigation. Through enhanced resonances, product species are readily
identified, leading to characterization of new hydride species including
catalytic intermediates. Cationic complexes are also under study as
possible electrophilic promoting agents and catalysts for bond activation
ans catalysis.
Studies on platinum and gold complexes relate to their excited state
properties and associated luminescence behavior. One line of
investigation involves square planar Pt(II) diimine complexes as
chromophores in the construction of molecular photochemical devices for
photo-induced charge separation corresponding to one of the fundamental
steps in artificial (and natural) photosynthesis. The chromophores are
linked to specifically positioned electron donors and acceptors through
different coupling strategies. Other work done in collaboration with
Kodak scientists relates to the use of luminescent metal complexes as
dopant emitters in OLED's for flat panel displays.
I received my B. S. and M. S. degrees in Chemistry from Addis
Ababa University, Ethiopia and my Ph. D. from University of Missouri-St.
Louis under the direction of Prof. Gordon K. Anderson in December 2002.
My research involves the design, synthesis and characterization of
cationic electrophilic platinum group elements. In probing the reactivity
of the electrophilic complexes, cationically promoted polymerizations,
organic transformations, and bond activation are examined. The intimate
mechanismis of these transformations are also addressed. If you are

I received my Ph. D. degree from Seoul National University in
South Korea on Feb. 2000, and then worked at Korea Institute of Science
and Technology (KIST) as a senior researcher.
My research activities focus mainly on the development of gold(I)
luminescent materials for possible use in OLED devices. Several series of
gold(I) compounds containing dithiophosphate, dithiocarbamate and
thiouracil ligands have been synthesized and studied, including new
heterobimetallic gold(I) systems. In these systems, gold(I) moieties
aggregate through 'aurophilic' interactions, which are critical in
controlling their crystal structures and luminescence properties.
Recently, bright blue gold(I) emitters that exhibit special tribochromism
in solid state luminescence and pH-dependent luminescence in solution,
have been developed. Subsequent effects will lead to elucidation the
nature of the emitting states. If you are interested in contacting me

I received my Ph.D degree in the year 2002, from I.I.T, Bombay
(INDIA) under the suprevision of Prof. G. K. Lahiri.
I am presently working in a project targeted to the design,
synthesis and study of multicomponent super- and supramolecular systems
for the photochemical hydrogen generation. The central component of these
systems is a chromophore comprised of a square planar coordinated Pt(II)
ion with both acetylide and polypyridyl ligands. The dyads and
corresponding triads will be constructed for facile flow of energy and
desired charge separation. In the presence of possible catalysts, assays
for hydrogen generation upon irradiation will be conducted and efficiency
will be compared with standard benchmark systems. If you are interested
in contacting me about my research, please feel free to contact me by

My research involves the synthesis and characterization of heavy
metal complexes which are useful dopants for OLED. Recently I have been
working on luminescent gold-silver clusters. Another part of my work will
involve making devices to study the electroluminescent behavior of these
systems. If you are interested in contacting me about my research, please

Rochester, Rochester, NY
My research involves luminescent platinum (II) diimine
bis(acetylide) and platinum (II) terpyridine acetylide complexes and
their incorporation into dyads, triads, and multicomponent systems for
light to chemical energy conversion. These complexe possess the
necessary excited state properties for their utilization in molecular
photochemical devices. Currently, we are constructing and studying a
number of intramolecular chromophore-donor (CD) and
acceptor-chromophore-donor (ACD) complexes with the goal of being able to
create long-lived photoinduced charge separated states.

I'm working toward my B.S. in Chemistry. I'm interested in
inorganic and organometallic reactions.
My research involves making and studying the luminescent behaviors
of gold (I) complexes. I'm using and coordinating different ligands that
will attached to the gold atoms to give these luminescent properties. If
