This paper demonstrates templated self-assembly-based on capillary forces-o
f millimeter-scale poly-(dimethylsiloxane) plates suspended at the water-pe
rfluorodecalin interface. The system described abstracts the concept of "te
mplating" from molecular templating and uses it to design millimeter-scale
aggregates that self-assemble in ordered structures. This work points the w
ay to new strategies for organizing complex, millimeter-scale structures.
