The mole fraction of dye to cyanobiphenyl molecules was varied from 0.5 to 0.02. One layer was successfully deposited onto a quartz plate with the transfer ratio slightly higher than one. The films were deposited at a surface pressure π between 1 and 15mN/m. The structure of the film at the air–water interface was observed by using a Brewster angle microscope. The orientation of cyanobiphenyl as well as dye molecules were estimated by polarized absorption spectra. The angle of the cyanobiphenyl <math><mtext>(β</mtext><msub><mi></mi><mn><mtext>H</mtext></mn></msub><mtext>)</mtext></math> molecules between the long molecular axis and normal to the quartz surface in pure and mixed monolayers was found to be between 64° and 54°.

PLL of low concentration (0.5mM) in the subphase of the LB trough as a counterion stabilized the protein at the air/water interface and enhanced the protein deposition efficiency onto the substrate. PLLs of various degree of polymerization (n=1, 5, 10, 15 and 20) were synthesized and the effect of each PLL was examined. Enhancement of the deposition of RC was observed using high n peptide (n=10, 15 and 20) but not using low n one (n=1 and 5). When PLL (n=1, 5, 10, 15 and 20) was added to the RC solution, the protein–protein association and the subsequent precipitation of RC occurred. Highly polymerized PLLs were effective on both RC deposition and RC precipitation suggesting that RCs spread at air/water interface were linked by PLL.
