Abstract
Abstract Aluminium is the most abundant metal in the earth crust and so far, there is no evidence on an important role in the human body. However, the relation of aluminium exposure on human health and aluminium‐related diseases is well known. The aim of this review is to summarize the most recent advances on multidentate organic compounds such as naphthalene, coumarin, quinoline, Schiff bases, benzothiazole, benzimidazole, rhodamine, pyrene carbazole, and julolidine derivatives as Al 3+ fluorescent sensor starting from an analytical viewpoint (sensibility, selectivity), their application in fluorescent bioimaging in vitro or/and in vivo , and photophysical mechanisms.
