Deep UV photochemistry of chemisorbed monolayers: patterned coplanar molecular assemblies

CS Dulcey, JH Georger Jr, V Krauthamer, DA Stenger, TL Fare, and JM Calvert

Geo-Centers, Inc., Fort Washington, MD 20744.

Deep ultraviolet (UV) irradiation is shown to modify organosilane self-assembled monolayer (SAM) films by a photocleavage mechanism, which renders the surface amenable to further SAM modification. Patterned UV exposure creates alternating regions of intact SAM film and hydrophilic, reactive sites. The exposed regions can undergo a second chemisorption reaction to produce an assembly of SAMs in the same molecular plane with similar substrate attachment chemistry. The UV-patterned films are used as a template for selective buildup of fluorophores, metals, and biological cells.
