Darryl Boyd admits there’s a downside to the chemistry he works on. Most of his research at the U.S. Naval Research Laboratory involves sulfur compounds, which can smell like rotten eggs. “I never thought I’d be a stinky chemist,” he says.
Boyd has taken this pungent chemistry and used it to synthesize unique polymers with impressive optical properties that could be used in fiber optics, displays, and night-vision goggles.
“There is a lot of sulfur, but we’re not doing much with it,” Boyd says. In 2014, the U.S. produced about 9 million metric tons of the element, according to the U.S. Geological Survey, and much of that comes from processing petroleum products. Finding chemical applications for this surplus could help mitigate the environmental risk of sulfur stockpiles across the country.
Sulfur can also enhance the properties of optical materials, Boyd explains. For example, eyeglass makers add sulfur-based materials to lenses to increase their focusing power. As a result, lenses can be thin and still focus light properly for people’s eyes.
One of Boyd’s sulfur projects involves a process called inverse vulcanization. Normal vulcanization uses sulfur to cross-link carbon chains to produce more durable forms of rubber. Inverse vulcanization flips that process on its head by using carbon molecules to cross-link sulfur chains.
Boyd was the first to incorporate sulfur’s periodic table neighbor, selenium, into these polymer chains to create what he calls organically modified chalcogenide polymers. These materials could be used in infrared optics, such as night-vision goggles, and one of the materials that Boyd synthesized boasts the highest refractive index ever for an optical polymer.
Although polymers are his current focus, Boyd’s academic background is diverse, including work on organometallic synthesis and biochemistry. Being able to move from field to field has helped him innovate, says Frances Ligler of North Carolina State University, who was Boyd’s postdoctoral adviser. Boyd sees connections between fields and can apply knowledge from one field to another, she says.
For Boyd, his current work highlights what he loves about chemistry—the ability to create something new.

Role model: George Washington Carver because he was so diligent in hammering away at research topics he was interested in—the science of peanuts and potatoes. My postdoctoral adviser, Frances S. Ligler, because despite her many research achievements, she has such a humble approach to advising chemists and to pursuing new research ideas.
If I were an element, I would be: Vibranium. It's ductile, malleable, and conductive. It has great, shiny luster, it's superstrong, and it makes for great movies!
