In exploiting topol. defects of liquid crystals as the targeting sites for trapping colloidal objects, previous work has relied on topog. features with uniform anchoring to create defects, achieving limited d. and spacing of particles. We report a generalizable strategy to create topol. defects on chem. patterned surfaces to assemble particles in precisely defined locations with a tunable interparticle distance at nanoscale dimensions. Informed by exptl. observations and numerical simulations that indicate that liquid crystals, confined between a homeotropic-anchoring surface and a surface with lithog. defined planar-anchoring stripes in a homeotropic-anchoring background, display splay-bend deformation, we successfully create pairs of defects and subsequently trap particles with controlled spacing by designing patterns of intersecting stripes aligned at 45° with homeotropic-anchoring gaps at the intersections. Application of elec. fields allows for dynamic control of trapped particles. The tunability, responsiveness, and adaptability of this platform provide the opportunities for assembly of colloidal structures toward functional materials.
