Simultaneously acquired (a) topographic and (b) polarizability STM images of a dodecanethiolate SAM with inserted nitro-functionalized OPE molecular switches. (c) Sequential images (30 s between frames) of individual switch molecules, showing instabilities in microwave polarizability image prior to visible switching in topographic image, and microwave peaks evident after topographic peak disappears.
