Optical Storage Properties of Novel Azo Dye-in-Polymer (PMMA) Thin Films

Fluorescence Behavior of Dyes in Thin Films of Various Polymers

“…The idea of incorporating dyes into a polymer matrix has attracted a great deal of interest as a simple fabrication scheme for functional devices. For example, thin polymer films containing fluorescence dyes have been extensively studied for sensors, − image patterning, − optical storage media, − and solar cells. − In these applications, one of the crucial points is to control the dispersion state of dyes in the polymer films. This is simply because aggregation formation of the dyes often alters the original fluorescence properties, such as the emission band position and lifetime. − In general, the dispersion state of dye molecules in a polymer is closely related to their miscibility.…”

Unveiling Electronic Transitions in Three Novel Chiral Azo-Compounds Using Linear and Nonlinear Circular Dichroism: A Theoretical−Experimental Study

“…Organic dyes containing the diazene group (−NN−), most commonly known as azo derivatives (R−NN−R′), form part of an extended family of compounds which have shown potential applications in major areas such as molecular sensing, − data storage, and nonlinear optics . The interest in this particular group of chromophores also resides in the relative ease of their synthesis and derivatization.…”
