Here we contrast the stability of monomeric and photopolymerized self-assembled monolayers (SAMs) containing a diacetylene group (HS(CH{sub 2}){sub 10}C=V@CC=V@C(CH{sub 2}){sub 10}COOH) with SAMs prepared from simple n-alkanethiols. The polymerized SAMs are extremely durable compared to either the n-alkanethiol SAMs or the unpolymerized diacetylenic SAMs. For example, they are stable to repeated electrochemical cycling to extreme potentials, thermal excursions to 200 {degree}C, and exposure to hot base (1:1 mixture of ethanol and 1.0 M aqueous KOH at 100 {degree}C). All of these conditions completely strip n-alkanethiol SAMs from Au substrates. These high performance materials are suitable for applications in lubrication, adhesion, corrosion passivation, and chemical sensing. 43 refs., 4 figs.
