TLDR
It is demonstrated that porphyrin-based molecules bound to Si(100), which exhibit redox behavior useful for information storage, can meet this challenge of competing with semiconductors under the extreme conditions required for processing and operating a practical device.Abstract:
If molecular components are to be used as functional elements in place of the semiconductor-based devices present in conventional microcircuitry, they must compete with semiconductors under the extreme conditions required for processing and operating a practical device. Herein, we demonstrate that porphyrin-based molecules bound to Si(100), which exhibit redox behavior useful for information storage, can meet this challenge. These molecular media in an inert atmosphere are stable under extremes of temperature (400°C) for extended periods (approaching 1 hour) and do not degrade under large numbers of read-write cycles (10 12 ).read more

TL;DR: Two alternative hypotheses are advanced to explain both the diminution in rates with increased surface coverage and the contrasting behavior with the analogous thiols on Au, one based on space-charge effects at the monolayer-solution interface and a second relying on changes in distance of the redox centers from the surface as modulated by the orientation of the linking chains.
