Polymer photonic crystals (PPCs) that selectively reflect visible light were prepared by triblock polymerization-induced ${it in situ}$ microphase separation via reversible addition-fragmentation chain transfer polymerization. The addition of homopolymer to the polymerization system swelled a specific phase of the microdomains, enabling the preparation of PPCs with long-wavelength structural colors. Small-angle neutron scattering confirmed the increase in the domain spacing of the lamellar microdomains with the addition of homopolymer, while maintaining their morphology.
