在研究中，我們藉由捕捉結構色彩技術，搭配著退火製程，可以得到具不同捕捉結構色彩的高分子共聚物之薄膜，並且呈現不同虹彩的光學特性。為了精確地去探討結構的有序程度，我們並量測光子晶體其虹彩光學性質變化，以波長差值與相應結構的半高寬做比較，發現隨著半高寬值的增加，波長差值會隨之減少。最後發現捕捉結構色彩特徵的共聚物之光子晶體薄膜能做為檢測有機蒸氣之偵測器。

In this study, we investigated trapping of structural coloration (TOSC) using the solid-state network-structured block copolymer thin films treated with an annealing process. Interestingly, control of iridescent reflection of photonic crystals (PCs) could be carried out in the TOSC-featured network-structured block copolymer thin films after the annealing treatment. To precisely investigate the iridescent reflection, wavelength difference and full width at half maximum of the network structure were proposed. With the increase of full width at half maximum, the wavelength difference decreases oppositely. Finally, the sensitivity for detecting organic vapor is studied using this solid-state block copolymer photonic thin film.
