PROBLEM TO BE SOLVED: To obtain a new compound useful as a raw material for a functional material such as nonlinear optical material, photosensitive material, polymer semiconductor crystal, etc., having solid-phase polymerizability. SOLUTION: This diacetylene derivative is shown by formula I (Ar is a bifunctional aromatic group; (m) and (n) are each 2-12). The compound of formula I is obtained by reacting a 1,3-alkadiynecarboxylic acid amide compound of the formula, CH3 -(CH2 )m-C≡C-C≡C-(CH2 )n -CONH-Ar-COOH or its acid halide with hydroxymethyltetrathiafulvalene of formula II in an inert gas atmosphere (e.g. nitrogen gas) in a solvent (e.g. methylene chloride) at 0-50 deg.C. The 1,3-alkadiynecarboxylic acid amide compound is obtained by reacting an 1,3- alkadiynecarboxylic acid compound of the formula, CH3 -(CH2 )m - C≡C-C≡C-(CH2 )n -COOR<1> (R<1> is H or a halogen) with an aromatic aminocarboxylic acid ester of the formula, H2 N-Ar-COOR<2> (R<2> is a hydrocarbon) and hydrolyzing the ester bond.
