  • Higher order structured dyes with enhanced optical features
    Patent number: 9970878
    Abstract: Organic dyes that are covalently bonded multimers or higher order symmetrical structures where one or more dye units may optionally contain deuterium substitutions are disclosed. The disclosed dyes are particularly useful for optical coatings, new optical nanomaterials, high density storage devices. The structural and optical characteristics of the disclosed dyes provide avenues for increased information-content through surface-enhanced Raman resonance spectroscopy.
    Type: Grant
    Filed: November 16, 2015
    Date of Patent: May 15, 2018
    Assignee: PURDUE RESEARCH FOUNDATION
    Inventors: Meiguo Xin, Vincent Jo Davisson
