Abstract

Wynalazek dotyczy zwiazków, pochodzacych 12-fenylo-12H-chinoksalino-[2,3-b][1,4]-benzotiazyny, o wzorze 1, w którym R1, R2 oznaczaja razem lub niezaleznie od siebie atom wodoru, chloru, bromu, grupe metylowa, etylowa, propylowa, metoksylowa lub etoksylowa, R3 oznacza atom wodoru a takze sposobu wytwarzania pochodnych 12-fenylo-12H-chinoksa-lino-[2,3-b][1,4]-benzotiazyny, o wzorze 1. Zwiazki te stanowia sensybilizatory w parach fotoredoks ze zwiazkami N-alkoksy-pirydyniowymi, trichlorometylo-1,3,5-triazynowymi lub difenylojodoniowymi i maja zastosowanie w procesie wolnorodnikowej, kationowej lub hybrydowej fotopolimeryzacji. Nadto zwiazki te moga byc stosowane jako barwniki fluoryzujace, gdyz wykazuja duze wydajnosci kwantowe fluorescencji.The invention relates to compounds derived from 12-phenyl-12H-quinoxaline- [2,3-b] [1,4] benzothiazine, of formula 1, in which R1, R2 are together, or independently of each other hydrogen, chlorine, bromine, methyl, ethyl, propyl, methoxy or ethoxy, R3 is a hydrogen atom as well as a process for the preparation of 12-phenyl-12H-quinoxo-amino- [2,3-b] [1,4] benzothiazine derivatives of the formula 1. Compounds these are photoredox sensitizers in N-alkoxy-pyridinium, trichloromethyl-1,3,5-triazine or diphenyl iodionium compounds and are used in the process of free radical, cationic or hybrid photopolymerization. In addition, these compounds can be used as fluorescent dyes because they show high fluorescence quantum yields.
