Diastereoselectivities as high as 98 % were the result of the photochemical ring‐closure of stereochemically pure copper( I ) helicates of a chiral oxazoline‐substituted 1,2‐dithienylethene photochrome (see scheme). The variations in optical rotation that accompany the photochromic event provide a means to read stored information in a nondestructive manner.
