Two new diacetylenes, 14‐amino‐10,12‐tetradiynoic acid (a diacetylenic aminoacid) and 10,12‐docosadiyndiamine (diacetylenic diamine), were successfully synthesized via Eglinton and Cadiot–Chodkiewicz coupling. These two diacetylenes and 10,12‐pentacosadiynyl amine (monoamine) were intercalated in mica‐type layered silicates, montmorillonite and vermiculite, via a cationic exchange reaction. The intercalation process was confirmed by X‐ray diffraction and Fourier transform infrared spectroscopy. The interlayer spacing and polymerizability of the intercalated diacetylene were found to depend upon the length of the diacetylene molecule, the layer charge density of the clay and the solvent treatment. The X‐ray diffraction pattern of vermiculite–diacetylene showed evidence of the in‐plane packing of the diacetylene. The polymerization of the intercalated diacetylene was confirmed by Raman spectra. © 1998 John Wiley & Sons, Ltd.
