Abstract
Fluorene derivatives are described including those having optical properties which can make them suitable for use in optical systems such as cameras. Various derivatives can have high polarity, small molecular volume, low glass transition temperature, high transparency and/or excellent optical characteristics. In addition, a process for making the fluorene derivatives and products made from the fluorene derivatives are described.
