Summary: This paper describes the synthesis and properties of functional opal structures, so‐called colloidal photonic crystals (CPCs), from a variety of reactive polymers. Photoprocessable opals are presented as well as opals with incorporated “smart” defect layers that can be actively addressed by external stimuli. In addition, opals with functional bio‐macromolecular defects have been developed. They present a new class of materials for optical biomonitoring through shifts of the induced photonic defect mode. Strong modification of photoluminescence according to the photonic bandstructure is observed from opals with embedded exclusively luminescent defect layer.
