A luminescent phosphonium-containing polyelectrolyte (P1-OHx) has been prepared by polymerization of a chromophore-containing diphosphine. The resultant cationic polyelectrolyte displays solvatochromism and undergoes facile layer-by-layer assembly with anionic poly(acrylic acid) to form smooth, well-defined films. Solution and film characterization by absorption and photoluminescence spectroscopy, and AFM imaging of films, are reported.
通过聚合含发色团的二膦,制备出了一种发光的含磷聚电解质(P1-OHx)。制备出的阳离子聚电解质具有溶解变色特性,并能与阴离子聚丙烯酸进行简单的逐层组装,形成光滑、清晰的薄膜。报告通过吸收光谱和光致发光光谱对溶液和薄膜进行了表征,并对薄膜进行了原子力显微镜成像。
