“…In recent years certain analytical approaches have been reported for the detection and quantification of bio‐relevant metal ions, but many of them are associated with various crucial drawbacks . But chemosensors based on fluorescent and optical signaling method turn out to be a promising device owing to its remarkable selectivity and sensitivity, portability, low cost, instant responds, naked eye detection facilities to estimate metal ions in analytical, medical, environmental and biological fields . However the detection of Al is always challenging than the other metal ions due to its high hydration ability in water, poor coordination ability and lack of spectroscopic characterization, thus development of a simple but very precise chemosensor for Al detection is a significant domain of research.…”
