FIELD: optics industry. SUBSTANCE: described is 2,3,7,8-thianthrenecarbonyl of formula I: which is used for preparing polyhexasocyctanes such as fluorophores, bifluorophores and trifluorophores. Such polyhexasocyclanes are promising for use as active media of liquid and hard lasers, scintillators, especially for indication of hard radiation, for transmission of short-wave length radiation into long-wave length radiation when transmitting information along fiber-optics communication lines. EFFECT: improved properties of the title compound. 2 ex |
