Abstract : The work performed under this AASERT grant augmented our efforts funded by the original parent grant 'Electrocrystallization of Molecular Solids?' and the recent renewal grant 'Electrocrystallization of Nanostructured Molecular Materials' (the AASERT grant overlapped the renewal of the two grants). The intention of the AASERT was to devise approaches to the synthesis and modification of electrocrystallized molecular materials aimed at (1) controlling the supramolecular structure of condensed phases through topological control of molecular networks during crystal growth and (2) nanoscale modification of existing materials using electrochemical atomic force and scanning tunneling microscopies. We have initiated a new discipline that is best described as two dimensional crystal engineering that uses molecular layer motifs in existing three dimensional crystal structures as the starting point for the design of organic thin film structures.
