Summary Acetic acid pulps (AAPs) have been converted to amphiphiles by hydroxypropylation. The resulting hydroxypropyl derivatives (HP-AAPs) formed self-aggregates in water. The interaction of HP-AAP molecules was investigated by a viscometric method. The reduced viscosity (η sp/c) of HP-AAP in both water and chloroform was increased remarkably above a concentration of 0.1%. This implies that HP-AAP molecules strongly interact with each other, caused by the hydrophobic interaction of residual lignins in water and by hydrogen bonding of polysaccharides in chloroform. The self-aggregates adsorb water-soluble fluorescent agents. The highest adsorption capacity was observed at the lowest pH among three pH conditions investigated. They also solubilized sparingly water-soluble fluorescent agents in water in larger amounts than did sodium dodecyl sulfate when used as a surfactant. These results suggest that the self-aggregates of HP-AAP adsorb low molecular mass compounds as inclusion compounds. To clarify the interaction of HP-AAP with biopolymers as high molecular mass compounds, the change in the activity of papain, a protease, in phosphate buffer (pH 6.2) was examined in the presence and absence of HP-AAP. HP-AAP acted as an inhibitor of papain at the initial stage of mixing. After mixing for 24 hours, however, the papain activity was revived and preserved for 6 days. In contrast, the papain activity vanished in the absence of HP-AAP after 24 hours because of autolysis. Therefore, HP-AAP protects papain against autolysis, resulting from tight complexation with the biopolymer.

Dodecyl Benzene Sulfonate

According to the principle of dynamic quenching a new ON-OFF fluorescent chemosensor for Cu2+ ions was designed, this chemosensor was composed of sodium dodecyl benzene sulfonate (SDBS), p-tert-butylthiacalix[4]arene (TCA) and perylene through the form of self-assembly in aqueous solution. Addition of Cu2+ ions could result in a quenching of the fluorescence emission of perylene inside micelles, which is ascribed to intramicellar complex-fluorophore electron-transfer or energy-transfer effects induced by the complexation of TCA with the Cu2+ ions.The results of the experiment indicated that: With the condition of TCA/perylene = 1000/1, SDBS concentration was 50mmol/L and pH value above 7, concentration of Cu2+ ion can be linearly determined according to the fluorescence quenching in a certain range.
