FIELD: biotechnology.
SUBSTANCE: invention relates to phenylbenzazole derivatives of general formula (A), wherein X is O or S; Q is a group (a), where R1 means -Cl, -NH(CH2)5CH3, -NHAr; R2 means -NH(CH2)5CH3, -N[(CH2)3CH3]2, -NHAr, or group (b), where R3 means -Ar(CH2)5CH3. Compounds of the invention are used as organic luminophores, more particularly those that do not have coloring in daylight, soluble in organic solvents (liquid hydrocarbons, alcohols, ethers, ketones, etc.) by organic phosphors.
, 
(a), 
(b).
EFFECT: new phosphors fluoresce in range from white to orange and can be used as components of fluorescent solvent, colorless in daylight, ink for inkjet printers, as well as components of organic ink stamps.
