The reflection spectra of molecular assembled metasurfaces were summarized in Fig. . When the polymer thickness is about 40∼50 nm, the resonance peak of the plasmon mode of MIM does not match well with the molecular absorption band. The maximum of (1 -R) is for the disk diameter around 500 nm. However, thin-film polymer layer acquire higher and stronger binding efficiencies, as shown in previous our studies . According to the recent results of Ashihara et al. in 2022 , at around 80 nm thickness there is a maximum value of the Rabi splitting
