“…Rhodamine dyes are halochromic dyes belonging to the xanthene family; they exhibit sensitive and rapid color change in an acidic environment. Because of their excellent stability and photophysical properties, rhodamine dyes are used in various fields, such as laser [5][6][7], imaging in living cells [8][9][10], fluorescence standards [11], and chemosensors [12][13][14][15].…”

For the immediate detection of gaseous strong acids, it is advantageous to employ colorimetric textile sensors based on halochromic dyes. Thus, a rhodamine dye with superior pH sensitivity and high thermal stability was synthesized and incorporated in nylon 6 and polyester fabrics to fabricate textile sensors through dyeing and printing methods. The spectral properties and solubility of the dye were examined; sensitivity to acidic gas as well as durability and reversibility of the fabricated textile sensors were investigated. Both dyed and printed sensors exhibited a high reaction rate and distinctive color change under the acidic condition owing to the high pH sensitivity of the dye. In addition, both sensors have outstanding durability and reversibility after washing and drying.

“…Among the different anions, acetate anion (AcO − ) plays an enormous role in our life, such as human metabolic process, protein synthesis [7][8][9][10][11]. For example, the abnormal rise of AcO − in the body could be the exogenous cause of urinary calculi [7,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. And AcO − can also interact with Ca 2+ to form calcium acetate, which is one of the constituents of urinary calculi [7].…”

A novelty chemosensor MM to detect AcO − was designed, synthesized and characterized. When MM interacted with AcO − , it was found that the new fluorescent emission peak at 616 nm arose. Meanwhile, the color change of the solution was directly observed by the naked-eye. Interesting, other anions could not cause any interference, specially F − , H 2 PO 4 − and PO 4 3−. The possible interaction mode between them was confirmed based on the Job's plot, 1 H NMR titration, ESI-MS, SEM analysis and DFT calculation. And LOD (limit of detection) of MM toward AcO − was 4.6 nM. Moreover, MM could be utilized as test strips to identify AcO − qualitatively. It's more important that MM could realize to detect AcO − in tap water quantitatively, rapidly and on-site by used of smartphone APP. Furthermore, MM was successfully applied to detect AcO − in living Caenorhabditis elegans. And it also demonstrated its potential bioimaging in living system.

Two novel water-soluble fluorescence probes T1 and T2 based on 5(6)-carboxyl rhodamine were designed and synthesized using a regioselective reaction. The probes exhibited highly selective and sensitive recognition toward Cu 2+ over other metal ions in acetonitrile/Tris-HCl buffer solution (2:98, v/v; pH 7.4). Detection limits were 0.4 μM for T1 and 4.50 μM for T2 based on fluorescence titration analysis. Furthermore, probe T1 was successfully applied in cell imaging experiments to monitor Cu 2+ in cells.
