Sodium and potassium ions enhance the fluorescence quantum yield of the N-(9-anthrylmethyl) monoaza crown ethers (1) in methanol by factors of up to forty-seven while all other electronic spectral… (More)
The importance of the modular structure ‘fluor-spacer-amine ’is pointed out for the design of fluorescent molecular sensors for pH according to the principle of photoinduced electron transfer (PET).… (More)
Abstract The reasons for the value of molecular fluorescence as a biosensing technique are outlined. The case of fluorescent sensors for cations is discussed with emphasis on a new general design… (More)
Abstract A photoinduced electron transfer cation sensor which can function as an off-on-off fluorescence switch for protons and an off-on fluorescence switch for zinc (II) ions is described.
Abstract We wish to report 4-[(Bis(pyridin-2-ylmethyl)amino)methyl]-7-methoxychromen-2-one, 1, as a fluorescent photoinduced electron transfer cation sensor that is capable of indicating the presence… (More)
Two new second generation fluorescent switches that are based on the chromophore–spacer–receptor architecture are reported in this paper. The fluorescence modulation of these switches is a result of… (More)
A molecular photoionic switch that responds to three cationic inputs with a primary ‘off-on-off’ and a secondary overriding ‘enable-disable’ fluorescence output, via the control of three separate… (More)
The fluorescent pH indicator parameters for compounds (1a) and (1b) are predictable within experimental error from the appropriate data for the constituent units 2- or 4-methyl benzoic acid and the… (More)
