“…When FRET mechanism exists, the excitation spectrum of TNP should overlap with the emission spectrum of PI. We know that the absorption spectrum of TNP is located at 410 nm 71 and partially overlaps with the emission spectrum of P1. Therefore, PL quenching mechanism is believed to be a two‐mechanism collaboration: PET and FRET coexist.…”

By using triphenylamine (TPA) with a propeller structure connected to the planar fluorene unit as monomer, three novel polyimide (PI)s were prepared through chemical imidization of N,N′‐(9,9‐bis(4‐(diphenylamino) phenyl)‐9H‐fluorene‐2,7‐diyl)‐bis(N‐(4‐methoxyphenyl) benzene‐1,4‐diamine) (TPAF‐NH2) with three kinds of dianhydrides. The three dimensional configurations are designed to decrease molecular stacking rising from strong imide bond, and for faster ion transport in cavity of PIs. All the three PIs have good performance of electrochromic(EC) and sensor. With the voltage increasing from 0 to 1.2 V, the color of P2 film changes from original yellow to red to blue with the response time of only 2.3 s (colored time [tc]) and 2.8 s (bleached time [tb]). The coloring efficiency (CE) of P2 reaches 310 cm2 C−1, with optical contrast (ΔT) of 54%. Especially, the electroactivity of P3 does not decrease significantly after 6000 s cycle. Additionally, there are dual‐band in near‐infrared (NIR) area after the PI being oxidized. P1 with photoluminescence (PL) quantum efficiency (φPL) of 48% can detect trinitrophenol (TNP) effectively. The novel PIs have promising prospect in NIR EC and TNP detection devices.

“…The absorption peaks at 1647.88, 1383.17, and 1110.49 cm −1 were attributed to the stretching vibration of N−H, C–H, and C−N, respectively. The characteristic C=O stretching peak at 1539.88 cm −1 were attributed to the amide group ( Lin et al, 2022 ; Yue et al, 2022 ; Zan et al, 2022 ; Xu, et al, 2023 ). It demonstrated that amide bond was formed between the TRFM and anti-PdG-mAb, which confirmed the successful coupling of TRFM and anti-PdG-mAb.…”

Introduction: Pregnanediol-3-glucuronide (PdG), as the main metabolite of progesterone in urine, plays a significant role in the prediction of ovulation, threatened abortion, and menstrual cycle maintenance.Methods: To achieve a rapid and sensitive assay, we have designed a competitive model-based time-resolved fluorescence microsphere-lateral flow immunochromatography (TRFM-LFIA) strip.Results: The optimized TRFM-LFIA strip exhibited a wonderful response to PdG over the range of 30–2,000 ng/mL, the corresponding limit of detection (LOD) was calculated as low as 8.39 ng/mL. More importantly, the TRFM-LFIA strip was innovatively used for the quantitative detection of PdG in urine sample, and excellent recovery results were also obtained, ranging from 97.39% to 112.64%.Discussion: The TRFMLFIA strip possessed robust sensitivity and selectivity in the determination of PdG, indicating the great potential of being powerful tools in the biomedical and diagnosis region.

“…Also, Li et al explored an amphiphilic fluorescent probe ( D57 ) via the functionalization of hydrophilic β-cyclodextrin with a hydrophobic AIE fluorophore. 397 The formation of spherical nanoparticles allows for more PA molecules to be captured and enhances interaction, promoting PET and improving the fluorescence quenching efficiency. An LOD of 0.31 μM was reported for D57 .…”
