Chemists break new ground in molecular machine research

Nick Vukotic, left, and Kristopher Harris are two of the team members who developed and tested University of Windsor Dynamic Material, UWDM-1.


A graduate student and his team of researchers have turned the chemistry world on its ear by becoming the first ever to prove that tiny interlocked molecules can function inside solid materials, laying the important groundwork for the future creation of molecular machines.
“Until now, this has only ever been done in solution,” explained Chemistry & Biochemistry PhD student Nick Vukotic, lead author on a front page article recently published in the June issue of the journal Nature Chemistry. “We’re the first ones to put this into a solid state material.”

This schematic shows how the various elements assemble themselves into mechanically interlocked molecules.

The material Vukotic is referring to is UWDM-1, or University of Windsor Dynamic Material, a powdery substance that the team made which contains rotaxane molecules and binuclear copper centers.  The rotaxane molecules, which resemble a wheel around the outside of an axle, were synthesised in their lab. The group found that heating of these rotaxane molecules with a copper source resulted in the formation of a crystalline material which contained structured arrangement of the rotaxane molecules, spaced out by the binuclear copper centers.

“Basically, they self-assemble in to this arrangement,” said Vukotic, who works under the tutelage of chemistry professor Steve Loeb. Other team members include professor Rob Schurko, and post-doctoral fellows Kristopher Harris and Kelong Zhu.

Heating the material causes the wheels to rapidly rotate around the axles, while cooling the material causes the wheels to stop, he said. The entire process can’t be viewed with a microscope, so the motion was confirmed in Dr. Schurko’s lab using a process called nuclear magnetic resonance spectroscopy.

“You can actually measure the motion and you can do it unambiguously by placing an isotopic tag on the ring,” explained Dr. Harris, who helped oversee that verification process.
Although the team admits their findings are still very much a proof of principle, they insist that molecules in solid materials can be manipulated to form switches and machines. This could be extremely significant and could find future applications in the fields of computer storage, data transfer or controlling the electronic properties of materials at the molecular level.

“Important metal organic frameworks like this are typically named after the university in which they were created,” Vukotic said of the material’s name. “It also emphasizes that this material is a prototype for other dynamic materials to come.”

Since the Nature Chemistry article appeared, a number of leading chemistry publications around the world have been reporting on the team’s findings, Dr. Loeb said.

“It’s a starting point,” said Loeb, who first imagined the concept about 10 years ago. “It’s a blueprint, but it’s the first demonstration of motion in a solid state. Normally when you make a new material you’re done. You can’t reorient molecules in a solid state.”

Chemistry grad Michael-Anthony Ferrato is the 2012 President’s Medal winner

Before he even got to the University of Windsor, Michael-Anthony Ferrato was helping new students get oriented to campus. It was a habit he kept up through his undergraduate career.

That level of involvement helped to earn the chemistry graduate the 2012 President’s Medal, awarded each year to a graduating student who has made significant contributions to campus and community activities while maintaining a superior academic record.

After his acceptance to the University in the summer of 2008, Ferrato produced videos documenting his experiences with academic orientation and course registration.

“We were looking for ways to get students involved and then we were pleased to find out Michael-Anthony was there ahead of us,” recalls liaison officer Tim Brunet. “He was helping to orient students by sharing his own experiences.”

After he started classes, Ferrato joined the recruitment team, acting as a guide for campus tours and working alongside staff and faculty to represent Windsor at the Ontario Universities Fair. He says that experience helped him see the many opportunities available on campus.

“I tell anyone who asks that the University of Windsor has everything they could want,” he says.

Ferrato made the most of his time here, holding an appointment as an Outstanding Scholar, getting involved in Lancer athletics, and pulling down top grades.

His work in the research lab of chemistry professor Tricia Carmichael brought him two summer research awards from the Natural Sciences and Engineering Research Council of Canada and earned him credit as a published author in a top academic journal.

He served as video coordinator for the Lancer basketball program; the broadcast he produced of the 2011 Canadian Interuniversity Sport women’s championship tournament was the primary feed for fans across Canada.

Ferrato is just as excited about his role as a co-founder and co-captain of the men’s baseball team: “With the talent we have in  this part of the province, it could be a powerhouse.”

And he earned places on the Dean’s List and President’s Honour Roll with a cumulative grade point average of 12.70 and a major grade point average of 12.90. Ferrato will continue his University of Windsor career in September as he pursues a masters degree in the Department of Chemistry and Biochemistry.

Chemists develop new method to make stretchable light-emitting devices

Chemistry student Heather Filiatrault and professor Tricia Carmichael examine a light-emitting device fabricated in their lab.

A common method of treating babies born with jaundice is phototherapy, which involves bathing the infant in light from fluorescent bulbs, halogen quartz lamps, light-emitting diodes, and even fiber-optic mattresses.

Tricia Carmichael can see a day when those babies can simply be wrapped in a light-emitting blanket.

An associate professor in chemistry and biochemistry, Dr. Carmichael spends most of her lab time studying ways of making flexible and stretchable electronic devices. In a recent Advanced Materials journal cover article – whose first author was grad student Heather Filiatrault – Carmichael and her colleagues describe an emerging method used to make light-emitting devices designed to tolerate strain so that they can stretch, bend and wrap.

“There are all kinds of cool applications for this technology, but the idea is to be able to make it inexpensively,” Carmichael said.

The challenge with making stretchable conventional organic light-emitting devices, which rely on technology currently used in cell phones, cameras and digital media players, is the device complexity, Carmichael said. The display screens on those devices consist of thin film layers and each one needs to have an element of elasticity.

Carmichael’s approach has been to reduce the device complexity by using light-emitting electrochemical cells, which rely on materials that give off light when voltage is applied, sandwiched between electrodes. Along with her team, Carmichael developed a way to make a light-emitting material—an organometallic ruthenium complex—stretchable by blending it with an elastic silicone rubber.

“It’s actually a fairly simple idea but no one has ever really done it before,” said Carmichael.

Under lab tests to measure its “stretchability,” the team found the material could achieve about 25 to 30 per cent elongation before the device failed to emit light.

 The concept is still in its infancy, but if developed it could have a wide range of potential applications from electronic display signs that could wrap around the corners of buildings to such health applications as light therapy used for healing wounds or activating certain chemotherapy drugs, Carmichael said.
