Methine dyes can be characterized as polyene dyes with terminal electron donating and accepting groups. In the majority of cases, these terminal groups contain nitrogen or oxygen atoms. However, while the naturally occurring polyene dyes (such as carotenoids) are limited to yellow to yellow-red tones, almost all colours of the spectrum can be achieved with the predominantly synthetic met… Web11 Sep 2024 · As a proof of concept, a series of target-activatable NIRII-RT probes (NIRII-RT-pH, NIRII-RT-ATP and NIRII-RT-Hg) for pH, adenosine triphosphate (ATP), and metal-ion detection, were synthesized.
