on the occasion of his 60th birthday Herein we describe a molecular structure, formed from labile components, that exhibits structural memory. The macroscopic model in Figure 1 demonstrates this principle. The wooden icosohedral puzzle retains its structure (without any glue) despite dissociation of
Photocyclizations of dipeptides 5 and 8 occur mainly with retention of configuration at the stereogenic center of alanine. This memory effect of chirality is explained by a hindered rotation in the two intermediate biradicals 9 and 10 that slows down the equilibration of the radicals.
