Bipyridyl-Dinitro Oligophenylene-Ethynylene Dithiol (BPDN-DT) Switch and Memory Storage

Single molecule makes electronic switch. ‘A single molecule, trapped between two electrodes, acts as a switch and has a ‘memory’ of the type used in data storage, Swiss and US researchers have found. Heike Riel of IBM’s research labs in Zurich says this is ‘a step along the way’ to making nanoscale electronic components a reality. Using single organic molecules as electronic components could allow researchers to miniaturise circuits far more than conventional techniques allow. They also avoid the interactions between the millions of molecules found in a standard transistor that can disrupt the conduction of charge.’

IBM researchers look beyond silicon technology and investigate molecules for the future of information processing. ‘Scientists at the IBM Zurich Research Laboratory have demonstrated how a single molecule can be switched between two distinct conductive states, which allows it to store data. As published today in SMALL, these experiments show that certain types of molecules reveal intrinsic molecular functionalities that are comparable to devices used in today’s semiconductor technology. This finding is yet another promising result to emerge from IBM’s research labs in their efforts to explore and develop novel technologies for the post-CMOS era.’ Three-terminal devices to examine single molecule conductance switching
