The methyl-ethynyl complex is from metal carbonyl-ethynyl complex, hexacarbonyl dicobalt complex of 1,2,4,5-tetrakis(phenylethynyl)benzene, hexacarbonyl diiron complex of 1,2,4,5-tetrakis(phenylethynyl)benzene, nona carbonyl triruthenium complex of 1,2,4,5-tetrakis(phenylethynyl)benzene, meta carbonyl-metallocenylethynyl containing complex, hexacarbonyl dicobalt complex of 1,4-bis(ferrocenyl)butadiyne, hexacarbonyl dicobalt complex of 1-(ferrocenylethynyl)-4-(phenylethynyl)benzene, and/or hexacarbonyl dicobalt complex of 1-(ferrocenylethynyl)-3-(phenylethynyl)benzene. The ethynyl compound is from ethynylaromatic compound, 1,2,3-tris(phenylethynyl)benzene, 1,2,4-tris(phenylethynyl)benzene, 1,3,5-tris(phenylethynyl)benzene, 1,2,3,4-tetrakis(phenylethynyl)benzene, 1,2,3,5-tetrakis(phenylethynyl)benzene, 1,2,4,5-tetrakis(phenylethynyl)benzene, 1,2,3,4,5-pentakis(phenylethynyl)benzene, and/or 1,2,3,4,5,6-hexakis(phenylethynyl)benzene. Preferred Process: The compounds are combined through mechanical mixing, solvent mixing, or partial complexation. The heating comprises heating the precursor composition under nitrogen to a temperature of greater than or equal to 300 degrees C. EXAMPLE - 1,2,4,5-Tetrakis(phenylethynyl)benzene (0.14 g) and iron-cobalt compound (Fe2(CO)9) (0.022g) were weighed into a 100 ml flask. Hexane (50 ml) was added and the resulting mixture was stirred rapidly for 5 minutes. The Fe2(CO)9 dissolved in the hexane without any color change, and upon concentrating at reduced pressure, little particles of the Fe2(CO)9 were deposited homogeneously throughout the 1,2,4,5-tetrakis (phenylethynyl) benzene, A sample (40.54 g) was heated at 10 degrees C/minute to 400 degrees C, and held for 4 hours. The X-ray diffraction analysis showed the formation of carbon nanoparticles and unidentified iron nanoparticle phase.
