Complexation and fluorescence behavior of diazacrown ether carrying two anthryl pendants

Photoinduced electron transfer (PET) fluoroionophores ( 1b, 2b) that consist of diazacrown and two 9-anthryl pendants show fluorescent enhancement with various guest salts. The diaza-12-crown-4 derivative ( 2b) exhibited Zn 2+ selectivity and in the presence of this cation the host fluorescence inte...

Zusammenfassung:	Photoinduced electron transfer (PET) fluoroionophores ( 1b, 2b) that consist of diazacrown and two 9-anthryl pendants show fluorescent enhancement with various guest salts. The diaza-12-crown-4 derivative ( 2b) exhibited Zn 2+ selectivity and in the presence of this cation the host fluorescence intensity was increased by a factor of 182. The guest cation-induced fluorescence enhancement of 2b was larger than the diaza-18-crown-6 derivative ( 1b).
