A New Protocol of Diels-Alder Lattice Hardening for Highly Efficient Electro-optic Materials Showing Outstanding Temporal Stability over

Introduction Organic electro-optic (EO) materials have attracted much interest in the past two decades because of their extensive potential applications in various fields, ranging from waveguides, switches, emitters, and detectors. Though EO materials have a huge potential in Photonics and Electronics devices, the fact that chromophores are not thermally robust enough to survive the device fabrication steps (short-term excursions to the order of 250oC) limits their application range. Technology description To better control the temperature window of electric field poling and lattice hardening processing, scientists at the UW have developed a new protocol for a lattice hardening, anthracene-acrylate based Diels-Alder Reaction. With their new crosslinking method, they developed a new class of EO dendrimers based on AJL8- type EO chromophores with much enhanced thermal and photostability. Business opportunity Organic electro-optic materials produced by this protocol may be used in Silicone Photonics and Electronics to accommodate the dramatically growing data traffic. Stage of development The new method has been used for the development of a new class of thermostable EO chromophores. Intellectual property position US and PCT patent applications are pending.
