Abstract
Novel fluorescent compounds having a specific structure are provided. They have improved solubility in organic solvents and compatibility even with low polar resins, especially silicone resins. Using the compounds, transparency fluorescent resin compositions are formulated. Since the fluorescent compound is a single compound, it can be purified to a high purity and has a high fluorescence efficiency.
