Single-Molecule Conductance data for a set of DPPA bischelated compounds and their precursors. See structures.png for chemical structures.

• Single-Molecule conductance data has been acquired using the STMBJ technique, with bespoke instruments developed in our laboratories.
All compounds measured at 100 uM concentration in mesitylene, at 500 mV tip-substrate bias..
Data is encoded in ASCII, as tab-separated data.

Format is as follows:

EMPTY COLUMN <tab> ELECTRODE POSITION <tab> JUNCTION CONDUCTANCE

- electrode position is in nm, referenced to the rupture of the atomic contact @ G = G0, where G0 is the conductance quantum
- junction conductance is log(G/G0) where G0 is the conductance quantum.
