一般描述

2-Ethyl-9,10-dimethoxyanthracene (EDMA) has been reported as a potential anthracene photosensitizer for diaryliodonium and triarylsulfonium salts.

2-Ethyl-9,10-dimethoxyanthracene is reported to possess antihistaminic activity. Photoinduced electron transfer from the singlet excited state of 2-ethyl-9,10-dimethoxyanthracene to CCl₄ has been reported. The photosensitized reductions of 4-cyanobenzylmethylphenyl sulfonium tetrafluoroborate by 2-ethyl-9,10-dimethoxyanthracene excited singlet state is reported to yield phenyl methyl sulfide.

应用

2-Ethyl-9,10-dimethoxyanthracene (EDA) has been used as sensitizer and its photoinduced (fluorescence quenching) reaction with 4-cyanobenzyl chloride has been studied.

2-Ethyl-9,10-dimethoxyanthracene may be employed as photosensitizer, to accelerate the photopolymerization. It may be employed as photosensitizer for enhancing the polymerization of benzothiazolium salts.
