Polyimide-Derived Supramolecular Systems Containing Various Amounts of Azochromophore for Optical Storage Uses.

ABSTRACT: The progress of digital technologies demands more speed and larger storage capacity. Optical storage systems have the advantage of being cheap, fast and capacious. This article explores the potential use of polyimide-based films as a recording medium for optical storage devices. The materials were designed through a host-guest approach that involves a cyano-containing polyimide precursor and an azochromophore combined in the following ratios: 1:0.25, 1:0.5, 1:0.75 and 1:1. After thermal treatment up to 200 °C, polyimide systems were formed with supramolecular structures constructed via hydrogen bonding as shown by molecular modeling and FTIR at around 3350 cm^-1. The aspects arising from the variation of the azo-dye content in the polyimide samples and their impact on the vitrifi
