PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2017; 186:8-16. [PMID: 28600993 DOI: 10.1016/j.saa.2017.06.004] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/17/2017] [Revised: 05/23/2017] [Accepted: 06/05/2017] [Indexed: 06/07/2023]
Abstract
Sensing of F-, CN- and Ac- is important from the viewpoint of both medically and environmentally. Particularly, sensing of the anions in 100% water by a colorimetric chemical sensor is a highly difficult task as water molecules interfere the sensing mechanism. In this regard, sensor R1, having azo and nitrophenyl groups as signaling units and thiourea as a binding site was prepared. This sensor exclusively detected CN- ion over other testing anions in 30% aq. DMSO solution by exhibiting distinct spectral and visual color changes. However, in 15% aq. DMSO solution, R1 exhibited obvious spectral and color changes in response to F-, CN- and Ac-. On the other hand, we have also designed sensor, R2, having same signaling units of R1, but a different binding site of urea group. Surprisingly, in contrast to R1, R2 exhibited obvious spectral and color changes in 5% aq. DMSO solution only. Further, economically viable "test stripes" were prepared in a facile mode to detect the CN- in 100% aqueous solution. Such stripes can serve as a practical colorimetric probe for "in the field" detection of the ions and thus avoid additional expensive equipment.

Indigo Carmine-Cu complex probe exhibiting dual colorimetric/fluorimetric sensing for selective determination of mono hydrogen phosphate ion and its logic behavior. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2017; 183:319-331. [PMID: 28458237 DOI: 10.1016/j.saa.2017.04.050] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2017] [Revised: 04/03/2017] [Accepted: 04/18/2017] [Indexed: 06/07/2023]
Abstract
A new selective probe based on copper complex of Indigo Carmine (IC-Cu2) for colorimetric, naked-eye, and fluorimetric recognition of mono hydrogen phosphate (MHP) ion in H2O/DMSO (4:1v/v, 1.0mmolL-1 HEPES buffer solution pH7.5) was developed. Detection limit of HPO42- determination, achieved by fluorimetric and 3lorimetric method, are 0.071 and 1.46μmolL-1, respectively. Potential, therefore is clearly available in IC-Cu2 complex to detect HPO42- in micromolar range via dual visible color change and fluorescence response. Present method shows high selectivity toward HPO42- over other phosphate species and other anions and was successfully utilized for analysis of P2O5 content of a fertilizer sample. The results obtained by proposed chemosensor presented good agreement with those obtained the colorimetric reference method. INHIBIT and IMPLICATION logic gates operating at molecular level have been achieved using Cu2+and HPO42- as chemical inputs and UV-Vis absorbance signal as output.
