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).
