Particle interactions, from pronounced dipolar plasmon coupling to noncoupling in colloidal monolayers with interparticle distances of hundreds of nanometers, are demonstrated. Macroscopically sized, hexagonal monolayers with exceptionally high degrees of order are fabricated in one step. Time controls the interparticle spacing and no further processing is required.
