摘要: Abstract An electron donating carbazole incorporated thiazole ( 3 ) based Zn 2+ selective intrinsic chemosensor has been synthesized and investigated. It was found that substituents such as methyl on 1 produce remarkable red shift in emission upon complexation with . The sensor shows a fluorescence response over biologically relevant cations (Ca , Mg Na + K non-relevant (Cd In 3+ Ga an aqueous ethanol system. also enhancement the quantum yield longer wavelength binding potential of ratiometric assay.
