AI Article Synopsis
- A new ratiometric sensor, (R)-1, was created to specifically detect aluminum (Al) ions while minimizing interference from other metal ions.
- The sensor's detection mechanism relies on changes in emission when excited, reducing unwanted interactions between its pyrene components.
- It effectively identifies Al ions at extremely low concentrations, even below the WHO's safety limit for drinking water.
Article Abstract
Pyrene-phenylglycinol tangled ratiometric sensor (R)-1 was developed for the detection of Al ion over other metal ions. Ratiometric behaviour of (R)-1 for Al ion explained through monomer emission and excimer quenching leads to avoiding the π-π interactions of bis-pyrene rings. Pull-push to push-pull binding mechanism is successfully explained by DFT and sensing of Al-ions demonstrated in living cells. The LOD of (R)-1 for Al downs to nanomolar concentrations which is lower than the allowed concentration of drinking water set by the (World Health Organization) WHO.
