Molecular structure and surface modification of monolayer organic films
نویسندگان
چکیده
Surface functionalization and its potential application in different fields of science and technology make monolayer organic films attractive candidates as linkages between an underlying substrate and other molecular species. By now, self-assembled monolayers (SAMs) [1,2] generated from either alkanethiols (RSH) or disulfides (RSSR) (R= CnH2n+1), have become a practical tool for homogeneous surface modification. Functionalization due to a characteristic surface energy can be tailored by choosing the desired specificity of the exposed end groups.

Organic semiconducting thin film growth on an organic substrate: 3,4,9,10-perylenetetracarboxylic dianhydride on a monolayer of decanethiol self-assembled on Au„111..
We use surface x-ray diffraction to study the structure of organic-organic heterojunctions grown by organic molecular-beam deposition. In particular, we study films of 3,4,9,10-perylenetetracarboxylic dianhydride ~PTCDA! grown on a decanethiol self-assembled monolayer ~SAM! on a Au~111! surface. The deposition of several ('16) monolayers of PTCDA results in unstrained crystalline films whose ~0...
