标题:Synthesis,Dual Fluorescence,And Fluoroionophoric Behavior Of Dipyridylaminomethylstilbenes
摘要:The Synthesis,Dual Fluorescence,And Fluoroionophoric Behavior Of Two Donor-Sigma Spacer-Acceptor (D-S-A) Compounds,Trans-4-(N,N-Bis(2-Pyridyl)Amino)Methylstilbene (111) And Trans-4-(N,N-Bis(2Pyridyl)Amino)Methyl-4'-Cyanostilbene (1Cn),Are Reported And Compared To That Of Trans-4-(N,N-Bis(2-Pyridyl)Amino)Methyl-4'-(N V-Dimethylamino)Stilbene (1Dpa). To Gain Insights Into The Dual Fluorescence Properties For 1H And 1Cn In Polar But Not In Nonpolar Solvents,Model Compounds Resulting From A Replacement Of The Stilbene Group By Alkyl (2R) Or Xylyl (2X) Groups Or From A Replacement Of The Dipyridylamino (Dpa) Group By Dianisoleamino (Ma),Diethylamino (Me),Methylanilino (Mp),Or Diphenylamino (3Pp) Groups Also Have Been Investigated. In Addition To 1H And 1Cn,All Four Compounds Of 3 Display Dual Fluorescence. The Locally Excited (Le) Fluorescence Mainly Results From The Stilbene Group And The Ict Fluorescence From The Through-Bond Interactions Between The Amino Donor And The Stilbene Acceptors. In The Presence Of Transition Metal Ions Such As Zn(II),Ni(II),Cu(II),And Cd(II),The Ict Processes Are Switched From Dpa (D)-> Stilbene (A) In 1H And 1Cn To Stilbene (D)-> Dpa/metal Ion (A) In Their Complexes. Whereas The Ict States For The Complexes Are Generally Nonfluorescent,An Exception Was Found For The Case Of 1H/zn(II). As A Result,Substituent-Dependent Fluoroionophoric Behavior Has Been Demonstrated By Iii,1Cn,And 1Dpa In Response To Zn(II).
