C(3)-functionalized cyclotriveratrylene derivative bearing quinolinyl group as a fluorescent probe for Cu(2+).
A new C(3)-functionalized cyclotriveratrylene (CTV) bearing three fluorogenic quinolinyl groups was synthesized and studied as a fluorescent probe. The CTV derivative exhibited a selective response of fluorescence enhancement toward Cu(2+). The fluorescence intensity in CH(3)CN was increased until the [Cu(2+)]/[CTV derivative] mole ratio was 3. Moreover, C(3)-functionalized CTV(2-quinolinemethyl)(3) was applied to a visible fluorescent probe by using a plasticized polymeric membrane. The emission profile was observed by a fluorescence microscope after immersing the membrane in a 1 x 10(-5) M aqueous solution of Cu(2+).
