Based on the five classes of fulgide family compounds, many realistic and potential applications have been developed and suggested for example, actinometry, optical storage, optical data processing, and nonlinear optical materials, optical waveguides, optical switches, security and printing applications, eyewear and leisure products. Applications of the fulgide family of compounds are discussed at the end of this chapter.
