| Abstract: | A novel amphiphilic zinc phthalocyanine(TAZnPc)was syntesized.Its behavior toward aggregation in different solvents was studied.Monolayers of pure TAZnPc and a 1:10 mixture of TAZnPc with 1-hexadecane were spread on water from ether solution andtransferred onto CaF2 slides. It is indicated that the mixed LB film is more stable than theLB film of pure TAZnPc. Multilayers were also built up on these substrates. Polarized UVabsorption spectra of the mixed LB films together with the molecule area in condensed mixedmonolayer lead to the conclusion that the phthalocyanine macroring is lying nearly parallel tothe substrate surface. |
