[en] Research on the acetylene compound 1,4-diphenylbutadiyne is an effort to develop a tritium gas getter that will operate in the presence of air and minimize the formation of water. T₂ adds to the acetylene bond of the getter in the presence of a metal catalyst. The catalyst stimulates the T₂-O₂ reaction as well. The butadiyne compound has shown good reaction efficiency for 300 ppM T₂ in static dry air at room temperature and one atmosphere pressure. Metalacetylene complexes are being synthesized, positioning the metal catalyst atom as close to the triple bond as possible to maximize the organic reaction. Organometallics such as triphenyl phosphine iridium are being investigated as possible regenerative getters for T₂ in air. Gas mixtures as low as 1 ppM T₂ in air will be tested under flow conditions in future work
