Chemistry in Pictures: Pappardelle Bolognese
by Alexandra Taylor
November 2, 2018
Zachary Schroeder, an undergraduate chemistry major at Wilfrid Laurier University, prepared this liquid crystal as part of his honors thesis research. The compound combines a polycyclic heteroaromatic core with flexible alkoxy chains. Schroeder will further transform the compound pictured in a multistep synthesis to try to produce an organic semiconductor. But for now, the lab he works in is interested in determining how a material’s molecular structure influences the range of temperatures in which the liquid crystals will form. Schroeder’s research adviser, Kenneth Maly, took this image through a polarized optical microscope as the material transitioned from the liquid-crystal phase to a liquid one. The vibrant hues are the result of polarized light refracting as it passes through the sample.
