    摘要:
    In this study, a novel ratiometric fluorescent sensor (HL) for Fe3+ based on the conjugation of rhodamine and coumarin has been designed and synthesized. The free sensor displays fluorescence emission at 475 nm, on the addition of Fe3+ to an aqueous solution of HL, the sensor shows significant fluorescence enhancement at 550 nm which should be attributed to an intramolecular fluorescence resonance energy transfer (FRET) mechanism from coumarin to Rhodamine 6G.

    rhodamine based receptors were developed as colorimetric and fluorescent chemosensor towards Cu2+. By using UV–Vis and fluorescence spectroscopy techniques, their selectivity and photophysical properties towards various metal ions were determined. The obvious color change from colorless to pink (under normal light) and non‐fluorescent to yellowish‐green fluorescent (under UV light) were observed upon the

    A simple rhodamine-based fluorescent probe L1, which exhibits good response to Fe3+ in CH3CN/Tris-HCl buffer (v:v = 9:1, pH 7.00) solution. With the experimental conditions optimized, the probe L1 could be used as a fluorescent and colorimetric probe for Fe3+ with the detection limit as low as 0.29 μM. The binding constant (Ka) of Fe3+ binding to the probe L1 were calculated to be 1.4 × 1010 M−2, respectively

    palladium, there is an urgent need for Pd2+‐sensitive and ‐selective probes. Based on the special affinity of Pd2+ to conjugated doublebond ligands, two fluorescence probes (RPd2 and RPd3) that contain conjugated allylidene‐hydrazone ligands that link to colorless rhodamine‐spirolactam have been developed. The results show that conjugated allylidene‐hydrazones have a much better affinity toward Pd2+
    由于钯广泛用于各种催化剂和转化器中,导致残留钯对水系统和土壤的高度污染,因此迫切需要对Pd 2+敏感和选择性的探针。基于Pd 2+对共轭双键配体的特殊亲和力,已开发出两种荧光探针(RPd2和RPd3),它们含有与无色罗丹明螺内酰胺连接的共轭亚烷基hydr配体。结果表明,共轭的亚芳基hydr对Pd 2+具有更好的亲和力,因此,与未结合的烯丙基肼相比,这些探针具有更敏锐的颜色变化和荧光增强(约170倍),以及比其他金属离子(尤其是铂族元素或PGE)更好的选择性。RPd2具有更高的电子密度和更合适的亚芳基hydr基团立体效应,对Pd 2+具有最佳的特异性,并且可以通过肉眼方便地检测到。概念验证实验证明了其在Pd 2+污染的水和土壤样品分析中的潜在应用。
