Original composites consisting of suspensions of astralenes with luminescent solubilizers in various solvents have been synthesized for the first time by the method of noncovalent solubilization. The spectroluminescence characteristics of such composites have been measured. A band corresponding to the S11 transition between van Hove singularities has been detected in the 1800-nm region in the absorption spectrum of a suspension of astralenes in a liquid crystal. The effect of optical limitation of laser radiation has been investigated in certain composites. A discussion is given of the role of noncovalent solubilization and of the formation of an ion-radical pair in the photodynamics of optical limitation in. © 2005 Optical Society of America
