A new fluorescent Al3+‐probe, N‐allyl‐4‐[3,3′‐((2‐aminoethyl)azanediyl)‐bis(N´‐(2‐hydroxybenzylidene)propanehy‐drazide)]‐1,8‐naphthalimide (L), was designed and synthesized based on 1,8‐naphthalimide. The probe L contains 1,8‐naphthalimide moiety as the fluorophore and a Schiff base as the recognition group. The structure of L was determined by single crystal X‐ray. L emission at 526 nm increased...
In this paper, a new chemosensor S1, N-n-butyl-4-[3,3'-((2-aminoethyl)azanediyl)bis(N'-(2-hydroxybenzylidene)propanehy-drazide)]-1,8-naphthalimide, has been designed and synthesized as an ‘‘turn-on’’ sensor for the detection of Al3+ with a high sensitivity and an excellent selectivity. The sensor S1 comprises 1,8-naphthalimide moiety as the fluorophore and Schiff base as the binding site. The structure...
