The defect tolerance of soft poly( N ‐isopropylacrylamide) microgels makes them good candidates for the synthesis of large colloidal crystals, which show no lattice defects, even in the presence of large dopant particles (see picture, the single dopant particle is circled). This result, together with progress in core–shell microgels with inorganic cores, should allow the preparation of photonic crystals with tunable bandgaps.
