摘要: Abstract This study investigated the influence of three transfer promoters on deposition and wettability characteristics copper tetra-tert-butyl phthalocyanine (CuTTBPc) Langmuir–Blodgett (L-B) films. With addition promoters, such as stearyl alcohol, stearamide, arachidic acid, two transitions corresponding to monolayer collapse were observed in surface pressure-area isotherms mixed CuTTBPc/transfer promoter monolayers at air/water interface. Nevertheless, expected enhanced stability a CuTTBPc presence did not reflect area relaxation curves obtained constant pressures. The ratio for L-B film glass substrate was close one, thus showed little improvement deposition. On gold-coated substrate, however, considerably improved by existence acid. Surprisingly, with alcohol or stearamide. Moreover, show significant films substrates except case
