Model of Hexaphenylbenzene Nanocube Molecular Structure (image) University of Tokyo Share Print E-Mail Caption Professor Shuichi Hiraoka at the University of Tokyo first created a self-assembling nanocube in 2008 and has worked to improve the solubility and temperature stability since then. The current self-assembling hexaphenylbenzene nanocube is soluble in water and stable up to 130 degrees Celsius (266 degrees Fahrenheit). The most recent publication from his research team identified the role of weak molecular forces in holding the box together. Credit Image by Shuichi Hiraoka CC-BY-ND. Originally published in Bull.
