Title: Innovations of Francisco M Raymo
Introduction
Francisco M Raymo is a notable inventor based in Coral Gables, FL (US). He has made significant contributions to the field of chromogenic materials and photochromic compounds. With a total of 5 patents, his work has implications in various applications, including displays, filters, and sensors.
Latest Patents
One of Raymo's latest patents involves the use of oxazine compounds for making chromogenic materials. These heterocyclic compounds can switch from a colorless state to a colored form upon the addition of either acid or base. The [1,3]oxazine ring opens in response to pH changes, forming an indolium cation or a phenolate anion. This process is reversible, allowing the original colorless state to be regenerated by returning the pH to neutral. Such halochromic compounds have potential applications in developing displays, filters, indicators, lenses, sensors, switches, or windows that can change color in response to pH changes.
Another significant patent focuses on photochromic compounds based on the ring opening and closing of an [1,3]oxazine compound. This molecular switch operates through photoinduced opening and thermal closing of the [1,3]oxazine ring. Irradiation by light of suitable wavelength cleaves a [C—O] bond, forming a phenolate chromophore. The photogenerated isomer can revert thermally to the original colorless oxazine. This reversible coloration can be applied to silica or polymeric materials, enabling the switching of optical signals.
