Competing Excited State Intramolecular Proton Transfer and Photoinduced Electron Transfer in 2-(2 -Arylsulfonamidophenyl)benzimidazoles
(Georgia Institute of Technology, 2008-05-05)
Cation-induced inhibition of excited-state intramolecular proton transfer (ESIPT) can be effectively utilized to design fluorescent probes for ratiometric Zn(II)-sensing. The 2-(2'-sulfonamidophenyl)benzimidazole family ...
High-contrast metal-responsive fluorescent probes based on synergistic electronic and conformational switching
(Georgia Institute of Technology, 2012-12-18)
We have prepared and characterized a Mg(II)-responsive fluorescent probe, constructed using a large tetradentate, 15-membered crown ether ligand and a 1,3,5-triaryl-substituted pyrazoline fluorophore. The photoinduced ...
