<p>PURPOSE: A quinolinium single crystal for nonlinear optics is provided to ensure macroscopic nonlinear properties and excellent tera hertz generation efficiency. CONSTITUTION: A quinolinium single crystal for nonlinear optics contains a quinolinium derivative of chemical formula 1 or 2 for a tera hertz(Thz) wave light source. In chemical formulas 1 and 2, R1-R7 are independently selected among hydrogen, hydroxyl, halogen, pseudohalogen, formyl, carboxyl, alkyl, long chain alkyl, alkoxy, long chain alkoxy, cycloalkyl, haloalkyl, aryl, arylene, haloaryl, heteroaryl, heteroarylene, heterocycloalkylene, heterocycloalkyl, haloheteroaryl, alkenyl, haloalkenyl, alkynyl, haloalkynyl, keto, ketoaryl, haloketoaryl, ketoheteroaryl, ketoalkyl, haloketoalkyl, ketoalkenyl, haloketoalkenyl, phosphoalkyl, phosphonate, phosphate, phosphine, phosphine oxide, phosphoryl, phosphoaryl, sulfonyl, sulfoalkyl, sulfoarenyl, sulfonate, sulfate, sulfone, amine, polyether, silylalkyl, or silylalkyloxy.</p> |
