Song, Fan; Shao, Xiaotao; Zhu, Jing; Bao, Xiaofeng; Du, Lei; Kan, Chun published the artcile< Reversible ""turn-off-on"" fluorescence response of Fe(III) towards Rhodamine B based probe in vivo and plant tissues>, Electric Literature of 950846-89-6, the main research area is fluorescence iron Rhodamine B probe plant tissue.
A Fe3+-specific probe (N-TC)(I) based on Rhodamine B was designed and synthesized. N-TC has a good spectral response to Fe3+ in the EtOH/H2O solution (1:1, volume/volume, HEPES, 0.5 mM, pH = 7.38) with low detection limits and high binding constants N-TC displays the reversible “”turn-off-on”” fluorescence response with 1:1 binding stoichiometry. It is further proven to be practical in sensitively monitoring trace Fe3+ in environmental water specimens. Biol. experiments demonstrated that N-TC can be resp. used as a probe for detection of Fe3+ in living cells, animals and plant tissues.
Tetrahedron Letters published new progress about Fluorescence. 950846-89-6 belongs to class indole-building-block, and the molecular formula is C30H36N4O2, Electric Literature of 950846-89-6.
