Related Products of 60804-74-2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate), is researched, Molecular C30H24F12N6P2Ru, CAS is 60804-74-2, about Luminescent Sensing Behaviors of a Lead Metal-Organic Framework and Its Binary/Ternary Composites: Increasing Selectivity and Sensitivity through a Multiemissive Approach.

Self-assembly reactions of Pb2+ and L2- (H2L = 4-(5,7-dioxopyrrolo[3,4-f]benzimidazol-6-yl)benzoic acid) lead to two new coordination networks: [Pb3(L)3(H2O)2]·10DMF·6.5H2O (1) is a metal-organic framework (MOF) with a 3D (3,3,8)-connected topol., and [PbL(DMSO)2] (2) has a 2D nonporous neutral (6,3) honeycomb network. 1 Can accommodate a green-emitting neutral dye (fluorescein, FRS) and/or a red-emitting complex cation ([Ru(bpy)3]2+, [Ru]2+) to form three series of multiemission composites: FRS@1, [Ru]2+@1, and (FRS+[Ru]2+)@1. Luminescence sensing experiments reveal that 1, B4 (0.017 wt % FRS@1), and G1 (1.261 wt % FRS + 0.463 wt % [Ru]2+@1) all show selective luminescence signal changes (emission intensities) toward different volatile organic solvents and nitroarom. vapors. However, G1 exhibits 2D ratiometric sensing behaviors based on the emission intensity ratios of IMOF/IFRS and IMOF/I[Ru]2+, which is much more selective and sensitive than the 1D ratiometric (IMOF/IFRS) sensing of B4 and the single-emission sensing of 1. These results reveal that the selectivity of the composite sensors could be well regulated by the incorporation of different luminescent modules, and the sensitivity can be improved by a multidimensional sensing approach.
