Chiral Recognition of 4,4’ Biphenyl Dicarboxylic Acid (BPDA) on fcc(111) Surfaces in Electrochemical Solutions Byung I. Kim, Department of Physics, Boise State University, Boise, Idaho 83725 BPDA/Au(111) BPDA/Pd(111) (15 nm x 15 nm) (46 nm x 46 nm) The goal of this project is to understand the influence of “molecular symmetry” of the composite structure of 4,4’ Biphenyl Dicarboxylic Acid (BPDA) /fcc(111) on the organic chiral recognition in the electrochemical environment. We investigated the influence by observing the structural configurations of BPDA molecules on two different substrates, Au(111) and Pd(111), in the perchloric (HClO4) acid by the electrochemical scanning tunneling microscopy (EC-STM). The EC-STM images show that BPDA molecules form Self-assembled hydrogen bond networks on both Au(111) and Pd(111). However, they showed different orientational ordering and packing density between Au(111) and Pd(111), indicating different recognition of BPDA molecules on the two different substrates. The theoretical model calculation suggests that the substrate dependent organic chiral recognition results from different substrate-adsorbate interactions between Au(111) and Pd(111). ri, R CB P a BPDA/fcc(111) Au(111) Pd(111)
