Abstract
AbstractChemiluminescence (CL) is a phenomenon in which a chemical reaction produces an excited-state product that emits light. Taking advantage of this property, several analytical methods to study the CL reactions by photon detection have been developed in the literature. By applying this methodology to molecular crystals, soft crystal CL systems have been constructed to analyze the intracrystalline reactions of chemiluminescent compounds. In this chapter, the fundamental concept and applications of CL are presented. Using the example of the CL reactions involving organic peroxides, important characteristics of CL such as chemiexcitation, quantum yield and emission wavelengths are discussed. Furthermore, CL in solid state and in molecular crystals are described. Finally, the application of organic peroxides as a soft crystal CL system and the characteristics of their intracrystalline reactions such as crystal structure-dependencies, reaction kinetics and inductions of phase transitions are elucidated. This chapter concludes with a brief outlook towards the future of soft crystal CL systems.
