Patent Abstract

Die Erfindung betrifft Arylthiocyamelurate, dargestellt durch die Formeln:wobei R4 Arylen, d. h. Phenylen, Naphthylen, Diphenylen, Triphenylen, R1, R2, R3 unabhängig voneinander S-Aryl, Cl, O-Aryl, O-Alkyl, O-Alkenyl,, O-Alkinyl, N-Aryl, N-Alkyl, N-Alkenyl, N-Alkinyl, Aryl, Alkyl, Alkenyl, Alkinyl sind und mindestens ein Rest S-Aryl ist für die Formel (1) bzw. ein verbindender S-Arylenrest ist für die Formel (2). Diese Arylthiocyamelurate werden durch Umsetzung von s-Heptazinchlorid mit Thiolen unter Inertgasathmosphäre in einem aromatischen Lösungsmittel bei Temperaturen größer als 100°C synthetisiert. Sie finden Verwendung zur Herstellung weiterer s-Heptazin-Derivate, zur Herstellung optoelektronischer Materialien, als Flammschutzmittel, zur Herstellung organischer Halbleiter, zur Herstellung von Photokatalysatoren zur Wasserstofferzeugung oder Spaltung organischer Schadstoffe, zur Metallfixierung auf Trägermaterialien und zur Metallgewinnung.
