Selective Deposition of Octasubstituted Phthalocyanine Materials Based on Hydrophobic/Hydrophilic Surface Interactions

摘要

Selective deposition of Octasubstituted phthalocyanine materials (MPc(OC_2OBz)_8, where M = H_2 or Cu) has been achieved using hydrophobic/hydrophilic surface interactions with a prototype patterned surface. The prototype surface, composed of ca. l0蘭 wide hydrophobic troughs alternating with ca. 15μm wide hydrophilic barriers is made using microcontact printing and electropolymerization techniques. AFM studies of these patterned phthalocyanines show the success of patterning these phthalocyanines from a cast solution, aerosol, Langmuir bilayer film, and using a capillary action technique.
