“…The SPCS systems constructed of core-shell microspheres have various structural control modes, and the objects to be etched include the core and shell. [238] For the opal PCs obtained by self-assembly of core-shell microspheres, hollow-sphere-type PCs can be obtained after removing the core (Figure 7b). [238,239] For soft shells, at high temperatures (greater than the glass transition temperature), the polymer materials of the shell can fuse with each other to form a more mechanically stable PC film.…”

Low‐swelling polymers (LSPs) generally refer to materials with a low solvent absorption ratio or volume expansion rate at swelling equilibrium. LSPs with exceptional responsiveness could be upgraded to smart sensors with structural color self‐reporting by bridging photonic crystals (PCs). Based on the regulation of swelling to effective refractive index, lattice spacing, the order‐disorder arrangement of nanostructures, and incident/detection angle, the structural color feedback of smart photonic crystal sensors (SPCSs) can quantitatively and visually reveal the stimulus, which greatly promotes the interdisciplinary development of nanophotonic technology in the fields of chemical engineering, materials science, engineering mechanics, biomedicine, environmental engineering, etc. Herein, to clarify the role of the photonic structures and polymer molecules in high‐performance SPCSs, LSP‐based SPCSs are summarized and discussed, including general swelling mechanisms, color change strategies, structural design, and typical functional applications. It aims to figure out the combination rule between PC structures and LSPs, optimize the design of PC structures, and expound the corresponding structural color sensing mechanisms, inspiring the fabrication of next‐generation SPCSs. Finally, perspectives on future structural design and sensing applications are also presented. It is believed that SPCSs are multifunctional nanophotonic tools for the interdisciplinary development of numerous engineering fields in the future.

“…Because photonic band gaps of PCs are related to effective refractive indices, it is quite difficult to detect homologues and isomers with similar refractive indices. Some researchers have tried to use complex PCs for detecting homologues and isomers. − For example, Ge’s group uses dynamic reflection spectroscopy to detect common solvents, homologues, and isomers (such as ethanol, propanol, butanol, and pentanol) based on a PC gel from SiO 2 particles, poly(ethylene glycol) methacrylate, and ethylene glycol . When the PC gel is infiltrated by different organic solvents, its lattice would undergo expansion or shrinkage and result in different dynamic reflection spectrum (DRS) patterns.…”

Photonic band gaps of photonic crystals (PCs) are related to the effective refractive indices; therefore, it is quite difficult to detect homologues and isomers with similar reflection indices by PCs. Some researchers have tried to use some complex PCs for detecting homologues and isomers. However, there are few reports in trace detection of isomers (cis−trans isomers) and mixed isomers by using simple amorphous photonic crystals (APCs). Herein, dynamic reflection spectrum (DRS) patterns of APCs are obviously different by changing species of compounds, mixtures of two similar isomers, volatility temperatures, and diameters of SiO 2 . Isomers with a refractive index difference of only 0.001 and their mixtures could be distinguished based on different DRS patterns of simple APCs. For example, the difference in the refractive indices of cis-3-hexene and trans-3-hexene is only 0.001, and the difference of desorption balance time of APCs is 142 s. The method shows high sensitivity detection in isomers and cis−trans isomers.

“…For instance, a vapor sensor constructed by PC and copolymer can adsorb alcohol vapor by relying on favorable solubility parameters, which increases the effective refractive index of the PC system. Therefore, as the PC sensor is exposed to volatile alcohol, a significant color change occurs, and the concentration of the alcohol vapor can be determined by the red-shift of the diffraction peak ( Fu et al, 2022 ).…”

A rapid curing method for the preparation of colloidal photonic crystal films is presented. Firstly, a colloidal crystal array template was prepared by self-assembly of nanospheres, and then a dilute polymer solution was poured into the gap of the template. Then the composite photonic film was obtained as the polymer solution was cured. Such films have good properties in mechanical strength, anti pH interference, rapid solvent response and are easy to preserve. The films show good linear response to ethanol aqueous solutions of different concentrations, and the response equilibrium takes less than 20 s. The films also show long-term stability and reusability, and further functionalization can make the films multi-sensitive.
