Controlling Microsized Polymorphic Architectures with Distinct Linear and Nonlinear Optical Properties

Controlled assembly of polymorphic organic materials into well-defined microstructures with specific properties is desirable for next-generation optoelectronic devices. Here, a multistep drop-casting technique is developed for the selective fabrication of kinetically and thermodynamically stable polymorphic microfibers and microplates with tunable optical responses in the linear and nonlinear optical regimes.
