Abstract:Mixed LB films of the CT complex of TMB·TCNQ and stearic acid (SA) were prepared. The structures, molecular orientation and morphology of the mixed LB films were characterized by IR, UV-Vis-NIR, XRD and AFM. Our results show that TMB·TCNQ could be deposited on solid substrates by mixing with SA. The complex is mixed-stack, and the degree of charge transfer is 0.35. The chromophore planes of both TCNQ and TMB are perpendicular to the substrate surface and the hydrocarbon chain of SA is inclined at an angle with respect to the substrate surface. There are two kinds of diffraction bands in the XRD spectra, and they probably arise from SA and TMB·TCNQ, respectively. The morphology of mono- and multilayer mixed LB films with molar ratio 1∶1 consists of many nanorods and particles, and the amount of nanorods and particles increase with increasing the number of monolayers.
