aqueous mixtures below 100 °C in air was reported. The as‐prepared fluorescent material has the features of facilepreparation, low cost, scalable production and easy to process, making it suitable for applications like fluorescent labeling and light‐emitting devices. This new finding opens a new venue for the preparation of fluorescent soft materials.
In one aspect, methods of sensing are described herein. In some embodiments, a method of sensing includes disposing a fluorophore in a biological environment, wherein the fluorophore includes a dioxo-pyridine ring (DPR) or a thiazolopyridine acid (TPA). The method further includes exposing the biological environment to electromagnetic radiation having a wavelength corresponding to an excitation wavelength of the fluorophore, detecting light emitted by the fluorophore, and correlating the light emitted by the fluorophore to a presence or absence of an analyte within the biological environment in an amount above a minimum detection threshold. The presence of the analyte can increase or decrease the amount of light emitted by the fluorophore. The presence of the analyte may also shift the peak emission wavelength or alter the fluorescence lifetime of the fluorophore. The analyte, in some embodiments, includes hydrogen ions, halide ions, and/or halogens.

temperature, a hydrogel was formed, and a thiazolopyridine ring was formed at a temperature of 140°C which was complexed with manganese. Infrared and electronicabsorption spectroscopy confirmed that manganese binding occurred via the oxygen atoms of COO. The complexes also exhibited strong fluorescence with excitation/emission peak wavelengths of 350/418 nm. The synthesized compounds showed efficient activity
