Template-Assisted Preparation of Micrometric Suspended Membrane Lattices of Photoluminescent and Non-Photoluminescent Polymers by Capillarity-Driven Solvent Evaporation: Application to Microtagging.

ABSTRACT: In this work, the bottom-up template-assisted preparation of high-density lattices (up to 11 · 10⁶ membranes/cm²) of suspended polymer membranes with micrometric size (in the order of few μm²) and sub-micrometric thickness (in the order of hundreds of nm) is demonstrated for both photoluminescent and non-photoluminescent polymers by capillarity-driven solvent evaporation. Solvent evaporation of low concentration polymer solutions drop-cast on an array of open-ended micropipes is shown to lead to polymer membrane formation at the inlet of the micropipes thanks to capillarity. The method is proven to be robust with high-yield (>98%) over large areas (1 cm²) and of general validity for both conjugated and non-conjugated polymers, e.g. poly(9,9-di-n-
