Three-dimensional (3D) ordered structure of PS@ZIF-8 and FT-ZIF-8 was prepared by self-assembly method. The 3D ordered structure of PS@ZIF-8 and FT-ZIF-8 were used to investigate the sensing characteristics for carbon tetrachloride in real time, and the two structures exhibited good response to carbon tetrachloride. It was found that the response time required to reach the maximum reflection peak only 2 s for FT-ZIF-8, and the shift of the reflection peak from about 825 nm to 836 nm of about 31 nm for PS@ZIF-8. The relationship of the shift peak position with different concentration of carbon tetrachloride was demonstrated to be linear. Moreover, The fabricated 3D ordered structures exhibited high long-term, repeatability and stability, which are beneficial for practical applications.[a] W.
