In the present paper, synthesis of a triboluminescent material is given that shows intense triboluminescent properties.
The very first compound Sweeting synthesized sparked in the dark, which makes it "the first compound designed to be a triboluminescent molecule," she says.
Triboluminescent materials possess the property of fracture induced light emission.
And her calculations suggest it "would be on the order of 0.005 percent [of their triboluminescent display]--way too little to see with current technologies."
By accident, Sweeting discovered that this compound also crystalizes into a second form that is not triboluminescent. By studying the differences between the two crystal structures, Sweeting was able to deduce why one form gives off light and the other does not.
