Abstract
Tetraethylene glycol (HO-(C2H4O)(4)-H) can be monofunctionalized by replaci ng ope of the terminal hydroxy groups with the thiol SH group. The resultin g molecule can be self-assembled on gold (111) surfaces. More importantly, this molecule allows the simple one-step preparation of protected, water-so luble gold colloids within a single aqueous phase. Attempts are made to use such protected water-soluble colloids as nucleating 'seeds' around which c alcium carbonate can be crystallized.
