Structural model of merocyanine dye Langmuir–Blodgett films with blue-shifted band

We have studied the red-shifted and the blue-shifted bands in the mixed Langmuir–Blodgett (LB) films of the merocyanine dye (MS)–arachidic acid (C20)–n-octadecane (AL18) ternary systems with the molar mixing ratio [MS]:[C20]:[AL18]=1:2:x (0.5≤x≤1.5). The overlapping spectra of the red-shifted and the blue-shifted bands are typically seen in the ternary systems and they are deconvoluted into the J- and H-bands. We compare the aggregation number N...
