Lithographically Patterned Breath Figure of Photoresponsive Small Molecules: Dual-Patterned Honeycomb Lines from a Combination of Bottom-Up and Top-Down Lithography

A line‐patterned breath figure film is achieved using a photo‐crosslinkable small molecule through a novel dual‐patterning process that combines a breath‐figure technique (bottom‐up) and photolithography (top‐down). The organogelator molecules form honeycomb structures, organizing into supramolecula...

Description
Summary:A line‐patterned breath figure film is achieved using a photo‐crosslinkable small molecule through a novel dual‐patterning process that combines a breath‐figure technique (bottom‐up) and photolithography (top‐down). The organogelator molecules form honeycomb structures, organizing into supramolecular fibers similar to polymers that stabilize water droplets.
