Nano‐ and Micro‐Engineering of Ordered Porous Blue‐Light‐Emitting Films by Templating Well‐Defined Organic Polymers Around Condensing Water Droplets

It's all in the casting: The pore sizes of nano-structured light-emitting films cast from linear and star-shaped macromolecular architectures can be engineered from the nano- to microrange by simply manipulating the casting conditions. The confocal microscopy image shows highly fluorescent organized porous materials with additional ordering within the polymer phase of the films.
