theoretical efficiency of solar cells made<br />
from the materials by as much as 30%.<br />
Wasielewski’s lab is also investigating<br />
quantum effects in organic materials with an<br />
eye toward quantum computing. His group<br />
is exploring a phenomenon known as “spin<br />
teleportation,” wherein the quantum state<br />
of a molecule at one location can be replicated<br />
at another location. With his organic<br />
materials, he says, his team is close to accomplishing<br />
this feat with light and to read<br />
the teleported states using microwave pulse<br />
sequences. The use of organic materials offers<br />
the potential to “deploy the arsenal of<br />
organic chemistry, including the tools of selfassembly,”<br />
to make materials for massively<br />
parallel computational systems, he says.<br />
Wasielewski was elected as a fellow of<br />
the American Association for the Advancement<br />
of Science in 1995. His recent honors<br />
include the 2004 Inter-American Photochemical<br />
Society Award in Photochemistry,<br />
the 2006 James Flack Norris Award in<br />
Physical Organic Chemistry from ACS, and<br />
the 2008 Porter Medal.<br />
When asked to sum up his work,<br />
Wasielewski says, “The magic word is multidisciplinary.”<br />
His research demands expertise<br />
in organic, physical, inorganic, and<br />
materials chemistry, as well as instrumentation.<br />
Jovan Giaimuccio, a former group<br />
member now at Independent Project Analysis,<br />
says, “The opportunity to be exposed to<br />
so many advanced forms of scientific experimentation<br />
gives Mike’s students the ability<br />
to discern scientific discovery from experimental<br />
artifact.” —CRAIG BETTENHAUSEN<br />
For young Jin-Quan Yu, his favorite chore<br />
was like a mystical quest. Every month, he’d<br />
trek to a store 2 miles from his home in a<br />
remote village in southeast China to collect<br />
free salt for his family. The vendor would<br />
give Yu empty linen bags that once contained<br />
kilograms of salt. He’d take the bags<br />
home, wet them, and evaporate the water to<br />
collect the salt crystals that emerged, as if<br />
by magic. Yu says he wasn’t thinking about<br />
chemistry then, but he’s pretty sure the experience<br />
was the first indication that he had<br />
“good lab hands.”<br />
Yu, 46, has since put<br />
his hands to use in C–H<br />
activation, arguably the<br />
hottest area of organometallic<br />
chemistry. He is “a<br />
phenom,” says University<br />
of California, Berkeley, organometallic<br />
chemist John<br />
F. Hartwig. “This guy is on<br />
fire and full of ideas.”<br />
A desire to study medicine<br />
led Yu to earn a bachelor’s<br />
degree in chemistry<br />
at Shanghai’s East China<br />
Normal University. “In the<br />
village it could get really<br />
Yu<br />
scary if you were ill,” Yu recalls. “We pretty<br />
much relied on Chinese herb extracts.”<br />
Yu earned his master’s under Shu-De Xiao<br />
at the Guangzhou Institute of Chemistry.<br />
There, Yu’s research led to a catalyst for<br />
ton-scale production of dihydromyrcenol,<br />
a lily-of-the-valley-scented compound used<br />
in shampoos and perfumes.<br />
Fascinated by enzyme catalysis, Yu attended<br />
the University of Cambridge to earn<br />
a Ph.D. with Jonathan B. Spencer. He then<br />
joined E. J. Corey’s Harvard University lab<br />
as a postdoc, hoping to do total synthesis.<br />
But Corey steered Yu toward another<br />
project—allylic C–H oxidation. Yu was reluctant<br />
at first, but became enthralled with<br />
the challenge of converting normally inert<br />
C–H bonds to C–C or C-heteroatom bonds.<br />
After Harvard, Yu began independent<br />
research back at Cambridge as a Royal Society<br />
Research Fellow. In 2004, he became an<br />
assistant professor at Brandeis University.<br />
In 2007, he moved to Scripps Research<br />
Institute, where he is currently a full professor.<br />
He’s garnered many honors, including<br />
a Sloan Research Fellowship, the Japanese<br />
Society of Synthetic Organic<br />
Chemistry’s Mukaiyama<br />
Award, and numerous<br />
awards from pharmaceutical<br />
companies.<br />
“I consider Jin-Quan’s<br />
pivotal contributions to the<br />
C–H activation field to be<br />
some of the very best in the<br />
area,” says Yu’s Scripps colleague<br />
and chemistry chairman<br />
K. C. Nicolaou.<br />
“Many groups have<br />
been focusing on sp 2 C–H<br />
bond functionalization,<br />
but Dr. Yu recognized that<br />
the chemistry of sp 3 C–H<br />
bond functionalization is potentially much<br />
richer,” says Huw M. L. Davies, who studies<br />
C–H activation at Emory University.<br />
In 2008, for example, Yu discovered the<br />
first palladium(II)-catalyzed coupling of<br />
sp 3 C–H bonds with sp 3 organoboron reagents.<br />
Yu’s team also developed the first<br />
palladium-catalyzed enantioselective C–H<br />
activation reactions. Yu says the key is using<br />
ligands that weakly coordinate to palladium.<br />
“By the time I retire, I hope synthetic<br />
chemists, particularly those in the pharmaceutical<br />
industry, will use C–H activation<br />
on a daily basis, like they do cross-coupling,”<br />
Yu says.<br />
In his spare time, Yu likes to play soccer.<br />
His favorite position? “Right wing,”<br />
Yu says. “I want to strike and score.” —<br />

GABOR SOMORJAI<br />
AWARDED HONDA PRIZE<br />
Gabor A. Somorjai, professor of chemistry<br />
at the University of California, Berkeley,<br />
is the winner of the 2011 Honda Prize<br />
for his pioneering contributions to surface<br />
chemistry. The Honda Prize, awarded<br />
by the Honda Foundation, is Japan’s first<br />
international science and technology<br />
award. The Honda Foundation was created<br />
by Honda Motor’s founder Soichiro<br />
Honda and his younger brother Benjiro<br />
Honda.<br />
Somorjai’s discoveries in surface chemistry<br />
and catalysis have led to a better understanding<br />
of friction, lubrication, adhesion,<br />
and adsorption.<br />
Somorjai’s peers refer<br />
to him as the “father of<br />
modern surface chemistry.”<br />
He received a<br />
medal, a certificate,<br />
and 10 million yen (approximately<br />
$129,000)<br />
during an award ceremony<br />
in Tokyo in<br />
November 2011. Somorjai<br />
