“…Indeed, these directional intermolecular interactions facilitate the preparation of the desired solid-state motifs and architectures (Gilday et al, 2015;Cavallo et al, 2016;Priimagi et al, 2013;Mukherjee et al, 2014;Shirman et al, 2015;Mukherjee et al, 2017). For example, using HBs and XBs, the specific organization of terminal diacetylenes (Li et al, 2009;Ouyang et al, 2003), bromodiacetylenes (Jin et al, 2015) and iododiacetylenes (Jin et al, 2013;Sun et al, 2006) has been obtained to achieve the solidstate topochemical polymerization of diacetylenes. On the other hand, to the best of our knowledge, no chlorodiacetylene topochemical polymerizations have been reported.…”
