  摘要：

  基于无环氨基酸受体的双荧光信号系统3展示了一种水诱导的同时双通道显色和荧光信号调制。其在各种有机溶剂中的微摩尔溶液在微量水存在下，通过水诱导的罗丹明染料去内酯化作用增强了吸收，从而呈现为颜色变化的可视感知。水分子的存在还有助于从激发态的硝基苯并噁二唑荧光团到3中的罗丹明染料的荧光共振能量转移（FRET），并导致发射强度增强到二级数量级。参考化合物2和4在类似条件下无响应，揭示了受体结构变化在光物理过程扰动中的作用。

• Hg(II) ion specific dual mode signalling in a thiophene derivatized rhodamine based probe and their complexation cooperativity

  The rhodamine based chemosensor 1 exhibited highly selective and sensitive detection of Hg(II) ion in MeCN-H2O mixture observable through amplified absorption and emission signals with a colour change from colourless to pink. Its thiophenyl subunit plays a predominant role in observed allosteric cooperativity in binding of both the Hg(II) ions of its 1:2 (L:M) complex stoichiometry. The anion induced 'turn-off' signalling responses of the Hg(II)-complex of 1 and subsequent 'turn-on' responses with further addition of Hg(II) here demonstrated its repetitive usability as a probe for Hg(II) ion detection.

  An acyclic amino-receptor based bi-fluorophoric signaling system 3 exhibits water-induced simultaneous dual channel chromogenic and fluorogenic signal modulation. Its micromolar solution in various organic solvents exhibits an enhancement in absorption in the presence of water in trace amounts through the water-induced delactonization of rhodamine dye, rendering a visual perception as a function of colour change. The presence of water molecules also facilitates a fluorescence resonance energy transfer (FRET) from the excited nitro-benz-oxa-diazole fluorophore to rhodamine dye of 3 and leads to an enhancement of emission up to a second order of magnitude. The failure of the reference compounds 2 and 4 to respond under similar conditions reveals the role of structural variation of the receptor on the perturbation of photophysical processes.
