Abstract:Three symmetrical diacetylenes (DAs)
bearing tetraalkylammonium
substituents have been prepared, namely, 1,6-bis(triethylammonium)hexa-2,4-diyne
diiodide (2), dinitrate (3), and bis[bis(trifluoromethylsulfonyl)imide]
(4). For these three salts, the duality between polymerization
and carbonization has been investigated, and the results have been
rationalized in terms of solid-state organization and molecular structure.
These DAs have been irradiated at 254 nm with concomitant annealing
at 80 °C (4) or 110 °C (2… Show more
