We have investigated thermal stability and adsorption structure of adipic acid (HOOC-(CH2)4-COOH) on Cu(110) surfaces as a function of sample temperature using temperature programmed desorption (TPD), low energy electron diffraction (LEED) and fourier transform infrared adsorption spectroscopy (FT-IRAS). From 350 to 400 K, adipic acid adsorbed as monoadipiate (HOOC-(CH2)4-COO−) forms corresponding structure of c(2×2). As the temperature increases until about 600 K, monoadipiate changes to biadipiate (−OOC-(CH2)4-COO−) corresponding structure of p(1×2) or p(6×2). Biadipiate structure is stable until 600 K and then desorption occurred.
