Self-assembled monolayers of new dendron-thiols - Manipulation of patterned surface and wetting property

Self-assembled monolayers(SAMs) based on a novel dendron-thiols system, whi ch maintain the alkanethiols ' active site , but the -SH group connected wi th independently variable groups by a dendron-linker, showed the controllab le surface pattern and wetting property. The precisely tailored structure o f dendron-thiols with local controlled hydrophobic and hydrophilic peripher ies allow the formation of designed surface structures on gold surface, e.g . nano-stripes, honeycomb and homogeneous structure.
