Here we discuss the preparation and characterization of photopolymerizable, self-assembled monolayers (SAMs) that consist of acid-, hydroxyl-, and methyl-terminated n-alkanethiols containing a diacetylene group (HS(CH{sub 2}){sub 10}C=V@CC=V@C(CH{sub 2}){sub 10}X; X=@COOH, CH{sub 2}OH, and CH{sub 3}, respectively). The acid and hydroxyl surfaces are readily amenable to further synthetic elaboration, while the methyl-terminated SAM results in a clean, low-energy surface. As demonstrated by Fourier transform infrared external reflectance spectroscopy (FTIR-ERS), surface-enhanced Raman spectroscopy (SERS), ellipsometry, UV-vis spectroscopy, and electrochemical methods, all three materials self assmble onto Au surfaces to form ordered monolayers that can be photopolymerized with UV light. 67 refs., 10 figs., 1 tab.
