4,4''-Diamino-p-terphenyl can be used to make selective hydrogen sensors that have high sensitivity, low consumption, and no cross-sensitivity to methane and ethane even at their operating temperatures and higher. Moreover, it is also used for studies of Symmetry breakdown of 4,4″-diamino-p-terphenyl on a Cu(111) surface by lattice mismatch[1-2].
