The photophysical investigation of two amino-alkyl receptor-based probes, 1 and 2, appended with two different rhodamine derivatives but differing in their receptor constituents revealed their selective absorption and fluorescence signalling responses to Fe(iii) among all metal ions investigated. Although the output channels in the complexation-induced signalling patterns of these probes are in proximity to each other, the spectroscopic signatures of Fe(iii)-complexation spiro-ring opening of the individual rhodamine derivatives and associated kinetic measurements revealed a preferential coordination affinity of the rhodamine 6G (Rho-6G) component over the rhodamine-B (Rho-B) segment. The Fe(iii)-selective signalling response was observed to be higher in flexible DETA(bis(2-aminoethyl)amine) receptor-incorporated probe 1 than in 2, which incorporates a rigid ethylenediamine receptor. The ratio of the fluorescence of the two wavelength output channels arising from the two different signalling subunits in the architectures of these probes enhances their sensitivity levels in Fe(iii) ion detection. The utility of the Fe(iii)-complexation-induced orange fluorescence output of 1 was demonstrated in the detection and localization of bio-accumulated Fe(iii) ions in root tissues of Grevillea pteridifolia plant species.
Fe(III)- and Hg(II)-selective dual channel fluorescence of a rhodamine-azacrown ether conjugate
Zhang, Xuan,Shiraishi, Yasuhiro,Hirai, Takayuki
, p. 4178 - 4181 (2008)
A rhodamine-azacrown ether conjugate (1) demonstrates Fe(III)-selective green fluorescence, while showing Hg(II)-selective orange fluorescence. This is the first example of rhodamine-based fluorescent probe that shows dual channel fluorescence for two different metal cations.
Strategy to Lengthen the On-Time of Photochromic Rhodamine Spirolactam for Super-resolution Photoactivated Localization Microscopy
Ye, Zhiwei,Yu, Haibo,Yang, Wei,Zheng, Ying,Li, Ning,Bian, Hui,Wang, Zechen,Liu, Qiang,Song, Youtao,Zhang, Mingyan,Xiao, Yi
, p. 6527 - 6536 (2019)
Rhodamine derivatives and analogues have been widely used for different super-resolution imaging techniques, including photoactivated localization microscopy (PALM). Among them, rhodamine spirolactams exhibit great superiority for PALM imaging due to a de
