Blends made from N-salicylidene aniline sulfonate derivatives and a polyampholyte matrix: in situ synthesis vs. solution mixing†
Abstract
Blend materials were prepared by the insertion of N-salicylidene aniline sulfonate derivatives inside an ampholyte polymer matrix. In addition to a classic insertion method based on homogeneous solution mixing, a new methodology was developed. The in situ synthesis of guest molecules inside the polymer taking advantages of the ionic nature of the dyes/matrix components is used for the first time for the preparation of blend materials with anionic anils. This method allows a strong electrostatic anchorage of the anion to the host matrix. Insertion occurs without perturbing the lamellar organization of the host polymer matrix. Infrared and diffuse reflectance UV-vis spectroscopies were implemented to investigate the host–guest interactions and an insertion model was drawn.
