Summary: A novel conjugated polymer, Co-P[5]Flu, was synthesized by copolymerizing pillar[5]arene and a fluorene derivative monomer. Co-P[5]Flu exhibited an aggregation-induced emission enhancement (AIEE) effect due to restricted intramolecular rotations. It showed high selectivity and sensitivity towards the pesticide paraquat (PQ) and had excellent anti-interference properties. The polymer acted as a fluorescence quencher only towards PQ and not towards other competitive guests, with a detection limit of 1.69x10-8 M.

Summary: A straightforward synthetic strategy using Suzuki-Miyaura/Scholl tandem reactions was employed to synthesize new series of annulated pi-extended poly-(hetero)aromatic hydrocarbons with carbazole, fluorene, and fluorenone central building blocks. The resulting compounds demonstrated strong aggregation tendencies in organic solvents and exhibited a wide range of liquid crystal phases, as well as high fluorescent quantum yields and excellent photocurrent behavior. This approach provides a potent and resilient method for the fabrication of various heteroarene molecular systems with potential applications in organic semiconductors and electroluminescent materials.

Summary: This study investigates the fluorescence spectra of BPF epoxy resin and identifies two emission peaks, one from the BPF epoxy monomer and the other from an aggregate structure. The aggregate structure is determined to be an H-aggregate based on experimental and theoretical calculations. Thermal exposure causes changes in the aggregate structure, allowing the fluorescence signal to serve as an indicator of polymer network rearrangement.

Summary: Two analogs of AIEEgen, BTD-CH-TPA and BTD-FL, were synthesized and showed fluorescence ranging from cyan-green to yellow in solution. However, intense fluorescence was observed in the solid state for both BTD-CH and its analogs. The outstanding AIEE effect of BTD-CH is attributed to its twisted conformation and the hindrance of deleterious π-π interactions by the bent aryloxy group.

Summary: A fluorescent chemosensor, 3-(Anthracen-2-yliminomethyl)-benzene-1,2-diol (ANB), was synthesized by condensation of 2-aminoanthracene and 2,3-dihydroxybenzaldehyde, and characterized using H-1-NMR, FT-IR, and Mass spectroscopic techniques. The ANB probe showed efficient 'turn-on' fluorescence for selective detection of Al3+ ion in an aqueous solution. The chemosensor exhibited a 27-fold enhancement of emission intensity in the presence of Al3+ ion.

Summary: New butterfly-shaped pi-extended sensors 4 and 5 were synthesized and employed for the sensitive detection of picric acid. These sensors showed ultra-sensitive fluorescence quenching response to picric acid, with a high quenching efficiency and a low limit of detection. Selective interaction of the sensors with picric acid was evaluated through various experiments, and the sensors were successfully applied for detection in real water samples. Furthermore, sensors' colorimetric recognition and coated test strips allowed for immediate naked eye detection of picric acid.
