(2) Please describe the functions of each of three key regions of Self-assembling molecules as shown in the figure. Surface interactions Strong interactions van der Waals forces Functional head group (e.g., CF3, OH, HC=O) van der Waals forces Assembling structure (e.g., alkyl groups) Attachment group (e.g., COOH, SH, SiH4, PO4) Substrate (e.g., gold, silica, aluminum oxide) (1) Please describe the chemical surface modification method, Self-Assembled Monolayers?
