“…With increasing [Fe 3+ ]/([Fe 3+ ]+[P1‐C6]), the emission intensity of P1‐C6 decreased accordingly, but no obvious turning point was observed (Figure 4d, the insert plot). That might be attributed to the weak coordination between Fe 3+ and the amido bond in P1‐C6 , which caused the electronic transmission between Fe 3+ and the electron‐rich TPB segments in polymer main‐chains, destroyed the radiation transition pathway and significantly weakened the fluorescence emission [36a,b] …”

Chiral aggregation‐induced emission (AIE) molecules have drawn attention for their helical self‐assembly and special optical properties. The helical self‐assembly of AIE‐active chiral non‐linear main‐chain polymers can produce some desired optical features. In this work, a series of V‐shaped chiral AIE‐active polyamides P1‐C3, P1‐C6, P1‐C12 and linear P2‐C3, P2‐C6, bearing n‐propyl/hexyl/dodecyl side‐chains, based on tetraphenylbutadiene (TPB), were prepared. All target main‐chain polymers exhibit distinct AIE characteristics. The polymer P1‐C6 with moderate length alkyl chains shows better AIE properties. The V‐shaped main‐chains and the chiral induction of (1R,2R)‐(+)‐1,2‐cyclohexanediamine in each repeating unit promote the polymer chains display helical conformation, and multiple helical polymer chains induce nano‐fibers helicity when the polymer chains aggregate and self‐assemble in THF/H2O mixtures. Simultaneously, the helical conformation polymer chains and helical nano‐fibers cause P1‐C6 produce strong circular dichroism (CD) signals with positive Cotton effect. Moreover, P1‐C6 could also occur fluorescence quenching response to Fe3+ selectively with a low detection limit of 3.48 μmol/L.

“…To date, several fluorescent sensors based on rhodamine, boron-dipyrromethene, chiral carbazole, metal-organic framework, polymers, etc., have been prepared for the detection of Fe 3þ ions; unfortunately, several shortcomings still exist including complex synthesis routes, poor water solubility, and high toxicity. [16][17][18][19][20][21][22] Therefore, it is important to design a facile, rapid, selective, and accurate fluorescent method for Fe 3þ detection.…”

Fluorescent nitrogen‐doped carbon dots (N‐CDs) are obtained by a straightforward hydrothermal method, and tartaric acid and L‐histidine hydrochloride are used as precursors. The obtained N‐CDs exhibit nanoscale structure, good water solubility, photostability, and excellent fluorescence (FL) properties with a high FL quantum yield of 19%. The designed N‐CDs are used as fluorescent probes for detecting Fe3+ with the FL “on‐off” strategy. Two good linear relationships can be observed for the concentration of Fe3+ from 0 to 80 μm and from 80 to 600 μm, and the calculated detection limit for Fe3+ is 0.88 μm (3σ/slope). Moreover, the N‐CDs‐based FL probe can also be used for detecting Fe3+ in tap water and possesses great potential application in the field of anti‐fake information encryption.
