Abstract
The University of Central Florida invention describes (1) a class of chromophore molecules and (2) processes for preparation. Non-linear optical effects in materials are important for highspeed optical modulation (optical communication, optical switches, sensors, terahertz generation and detection) as well as other applications like organic photovoltaic devices (for example, OLEDs). The zwitterionic twisted intramolecular charge transfer (TICT) chromophores are predicted to have second-order nonlinearity that is several times greater than that of the commonly used neutral chromophores and to have increased stability. These molecules could be incorporated into a host polymer to induce electro-optic activity (an aligning and freezing method known as “thermally assisted electric poling”). The preparation method is more customizable than currently used synthetic methods, since the physical properties of these materials can be tuned when embedded in a device.
