1. Organic Nanocrystal DiscoveryLeonard R. MacGillivray, University of Iowa, DMR 1104650 Intellectual Merit The MacGillivray research group focuses on the crystal engineering of the organic solid state. During experiments to study the solid-state self-assembly of bowl-shaped molecules known as resorcin[4]arenes, the group reported on the ability of the molecules to form crystals of nanometer dimensions (Fig. 1). Crystal with shapes that conform to hollow shells formed, which had previously only been observed with inorganic solids. The design of organic nanocrystals is expected to afford novel materials with applications in catalysis, sensing, and device development. Fig. 1. Cover article on organic nanocrystals. Sander, J. R.

2. Visiting Four-Year College Faculty and Nanocrystals Leonard R. MacGillivray, University of Iowa, DMR 1104650 Broader Impacts i) Visiting faculty member Prof. Ryan Groeneman of Jefferson College in St. Louis, Missouri co-published a paper with the MacGillivray group in the prestigious journal Angewandte Chemie on protecting groups in template-directed solid-state reactions (Fig. 2). ii) Published work on organic nanocrystals by the MacGillivray group was featured in an interview Podcast at the website of The Journal of the American Chemical Society. The interview provides a five-minute audio description of the work. The Podcast is free and open to the public. Fig. 2.Esters as protecting groups in template-directed solid-state reactions.
