Poly[bis-(p-toluene sulphonate) of 2,4-hexadiyne- 1,6-diol] langmuir-blodgett thin film formation and characterization

Coherent thin films of bis‐(p‐toluene sulphonate) of 2,4‐hexadiyne‐1,6‐diol (TS) and its polymer, PTS, were prepared by the Langmuir‐Blodgett method. Even though TS has no amphiphilic groups at each end, it has an isotherm curve similar to stearic acid and can be transferred to a flat solid substrate under a certain pressure. Polarized UV‐Vis spectroscopy, atomic force microscopy (AFM) and scanning electron microscopy (SEM) were used to characterize this kind of LB thin film's anisotropy, surface morphology, and topography.
