Scientists have used self-assembly to create a nanoscale molecule that, like snowflakes and coastlines, has a self-similar fractal form. The hexagonal gasket is composed of of six rings, which are made up of six rings, and so on. The University of Akron and Clemson University researchers presented their creation in the journal Science.
From Ohio University Research News:
"This man-made structure is one of the first nanoscale, non-branched fractal molecules ever produced," said (George) Newkome, who is lead author on the Science paper and also serves as dean of the Graduate School and the James and Vanita Oelschlager Professor of Science and Technology at the University of Akron. "Blending mathematics, art and science, these nanoscopic hexagonal-shaped materials can be self-assembled and resemble a fine bead necklace. These precise polymers – the first example of a molecule possessing a 'Star of David' motif – may provide an entrée into novel new types of photoelectric cells, molecular batteries and energy storage."
