Selective deposition of Langmuir-Blodgett films of a phthalocyanine onto patterned substrates

Abstract : In the present note, we study the LB deposition of a fully hydrophobic molecule onto substrates patterned at the micron scale with periodic hydrophobic and hydrophilic areas. Using a molecule which does not deposit on large hydrophilic areas is expected to give rise to a selective deposition on the patterned substrate. It has been shown that nickel tetrakis(hexyloxycarbonyl)phthalocyanine (PcE6) is easily transferred onto purely hydrophobic substrates with a 0.975 transfer ratio and does not deposit on hydrophilic substrates.7 In the LB films, the Pc rings stand on the edge and form columns almost parallel to the transfer axis (dipping direction). Tapping mode AFM revealed that the one-layer-deep defects observed in the topmost layer are also oriented by the transfer.7 The major mechanism of orientation of the columns has been shown to be the so-called flow orientation effect, which occurs during the transfer
