Abstract

In this paper we introduce three new types of self-assembled (SA) monolayer films of organic thiourea system based on substituted phenylthioureas: p-methylphenylthiourea (C₈H₁₀N ₂S), p-chlorophenylthiourea (C₇H₇ClN ₂S) and 2,4,6-tribromophenylthiourea (C₇H₅Br₃N₂S). We focus on the synthesis of organic thiourea and the preparation of these three films by chemisorption from solution onto the Au(111) surface. In addition, we discuss the order-orientated property of SA films and several molecular film analyses using CA, IR, SEM, XPS, and AFM
