Research progress of auxiliary groups in improving the performance of fluorescent probes

Abstract

In the design work of fluorescent probes, it is important to consider not only the factors of fluorescence properties but also the environment in which the fluorescent molecule works. This...

Blue fluorescent waterborne polyurethane‐based transition metal complexes with antibacterial activity

“…The fluorescence color changes from blue‐green to blue. It is mainly due to the change in the charge distribution of 5‐AQ after the reaction of NCO with NH 2 in the complexes, which changes the internal resonance structure and reduces the luminescence ability of the luminescent group 32 . Due to the strong ionic properties, the luminous properties are changed by using different transition metal ions, which have potential applications in LED white light tuning.…”

Existing white LEDs are generally achieved by mixing red, yellow, and blue colors in a narrow band of LEDs, and few materials are currently available to create high-efficiency LEDs at multiple emission wavelengths.…”

Exploring the fluorescence properties of tellurium-containing molecules and their advanced applications

“…Current research endeavors in the realm of fluorescent probes are dedicated to enhancing sensitivity and selectivity, achieving meticulous cellular targeting, advancing diagnostics and in vivo imaging capabilities, developing responsive probes, integrating with diverse materials, exploring environmental applications, and ensuring biocompatibility for secure biological applications. [103][104][105][106][107][108][109] However, these efforts also grapple with significant challenges, including issues related to photostability, specificity in complex biological environments, scalability for widespread use, and the development of probes capable of withstanding diverse physiological conditions. [110][111][112][113] Addressing these challenges is crucial for the successful implementation of fluorescent probes in various applications, ranging from medical diagnostics to environmental monitoring.…”

Two near-infrared phosphorescent iridium(iii) complexes for the detection of GSH and photodynamic therapy

“…38 The electrostatic attraction played a dominant role in Ir1 and Ir2 probes; the positive charges on the iridium(III) metal centre prefer the more negative charges on GSH and promote the addition of the sulfhydryl group of GSH. 39,40 Because the content of GSH in cancer cells is much greater than that of Hcy and Cys, another interference experiment was designed. As shown in Fig.…”
