In this work, we studied guest-host interactions between various dye mols. and the fifth-generation poly(propylene imine) (PPI-5) dendrimers in aqueous solutions using a surface plasmon resonance (SPR) sensor. The effect of the properties of guest and host mols. (e.g., charge and shape) and media (e.g., pH and ion strength) on affinity between guest and host mols. was studied. Based on an immobilized homogeneous monolayer of PPI-5 dendrimer tethered to carboxyl-terminal self-assembled monolayers, the adsorption behavior of a group of dye mols. in PPI-5 was obtained. The strong affinity of PPI-5 to Rose Bengal and erythrosine B is attributed to the good match in charge and shape between the cavities of the dendrimer and the dye mols. Maximum adsorption around a pH value of 7 was observed The kinetic behaviors of different dye mols. in dendrimers were also studied. A fundamental understanding of guest-host interactions in dendrimers will guide the design of new-generation sensors and drug delivery carriers.
