How penetrable are thioalkyl self-assembled monolayers?

Abstract:

The depth of penetration of photolytically generated, gas-phase O( 3P) atoms into thioalkyl self-assembled monolayers (SAMs) has been investigated. Custom-synthesized, site-selectively deuterated SAMs were prepared on Au substrates and characterized by scanning tunneling microscopy (STM). Relative yields of gas-phase OD were detected by laser-induced fluorescence (LIF). Reaction was suppressed at the terminal CD3 by the higher abstraction barriers for primary D atoms, yielding only 16 ± 3% of...
