Polymers containing backbone fluorescein, phenolphthalein and benzaurin. Synthesis and optical properties

Abstract

In order to utilize the prominent fluorescence ability of fluorescein in light emitting devices, we have synthesized a series of polymers that contain fluorescein in their backbones. The key step of the synthesis, in which the fluorescein unit and the polymer are created simultaneously, is the reaction of bis(2,4-dihydroxyphenyl)alkanes with phthalic anhydride. This new methodology was also used for the synthesis of polymers containing phenolphthalein and benzaurin. All the new polymers completely maintained the optical and chemical characteristics of the parent pigment.
