In view of possible solid-state polymerizations of crystalline stacked 'push-pull'-acetylenes 1, a series of compounds 1 has been synthesized (Scheme 3), and the results of X-ray analyses of 'push-pull'-acetylenes 1d,e,f are discussed. Of these three compounds, methyl 2-morpholinoacetylene carboxylate (1d) is by far the best candidate giving crystals with nicely stacked molecules (Fig. 3), Even in this case, however, stacking parameters d = 4,12 A and a = 31,6°are too large for allowing solid-state polymerizations.
