Polycatenar Ligands Control Nanocrystal Synthesis and Self-Assembly

Penn-COMPASS Partnership: IRG4/Solvay/CNRS

IRG-4 creates new forms of matter by assembling nanometer-sized crystals into large, ordered, complex assemblies (nanocrystal superlattices. 

Murray (IRG-4) and Donnio (CNRS) have synthesized a library of molecules (polycatenars) that enable new kinds of nanocrystals and superlattices.

Broader Impact

Lego Optics Lab @GEMS Summer Camp

The Kagan (IRG-4) group created a Lego Optics lab for Penn’s Girls in Engineering, Math and Science (GEMS) summer camp for 6th-8th grade girls.

Middle school girls learn about the reflection, refraction, polarization, and diffraction of light hands-on. Lego is used to build mounts for light sources, optical elements, and detectors and the interaction of light with matter.
