AI Article Synopsis
- The novel imidazole derivative PIPP is identified as a highly sensitive chemisensor for detecting transition metal ions and serves as a versatile optically switchable material.
- Research shows that the fluorescence properties of PIPP are affected by the polarity and protic nature of various solvents, indicating a solvatochromic effect.
- The study highlights a FRET process between PIPP and a bioactive indoloquinolizine molecule, suggesting that long-range dipole-dipole interactions are key to the energy transfer, with quantified energy transfer efficiency and donor-acceptor distance.
Article Abstract
Novel donor imidazole derivative, 2-(1-phenyl-1H-imidazo [4,5-f][1,10]phenanthrolin-2-yl)-phenol (PIPP) was screened as highly sensitive chemisensor for transition metal ions and it can be used as a "multi-way" optically switchable material. Solvatochromic effects on the fluorescence behaviour of PIPP were studied in different solvents. The fluorescence of PIPP was highly sensitive to both the polarity as well as protic nature of the solvent. Fluorescence (Forster) resonance energy transfer (FRET) process from PIPP to a potent bioactive indoloquinolizine molecule was studied and it is argued that long-range dipole-dipole interaction is operating for the energy transfer mechanism. The energy transfer efficiency (E) and the distance between the acceptor and the donor (r(0)) have been determined.

Sequential addition of cations increases photoluminescence quantum yield of metal nanoclusters near unity.

State Key Laboratory of Integrated Optoelectronics, College of Electronic Science and Engineering, Jilin University, Changchun, P. R. China.
Photoluminescence is one of the most intriguing properties of metal nanoclusters derived from their molecular-like electronic structure, however, achieving high photoluminescence quantum yield (PLQY) of metal core-dictated fluorescence remains a formidable challenge. Here, we report efficient suppression of the total structural vibrations and rotations, and management of the pathways and rates of the electron transfer dynamics to boost a near-unity absolute PLQY, by decorating progressive addition of cations. Specifically, with the sequential addition of Zn, Ag, and Tb into the 3-mercaptopropionic acids capped Au nanoclusters (NCs), the low-frequency vibration of the metal core progressively decreases from 144.

CO/CH separation is crucial for biogas upgrading. In this study, the bamboo-derived activated carbons (BACs) were prepared with different ratios of potassium hydroxide (KOH)/bamboo charcoal (BC), and the hybrid sorbents of aqueous BACs were developed for CO/CH separation. Both the gas solubility and sorption rate were measured, and Henry's constant and liquid-side mass-transfer coefficient as well as the CO/CH selectivity were calculated.

Excess biological sludge processing and disposal have a significant impact on the energy balance and economics of wastewater treatment operations, and on receiving environments. Anaerobic digestion is probably the most widespread in-plant sludge processing method globally, since it stabilizes and converts biosolids organic matter into biogas, allowing partial recovery of their embedded chemical energy. A considerable number of studies concerning applicable techniques to improve biogas production, both in quantity and quality, include pre-treatment strategies to promote biosolids disintegration aimed at the release and solubilisation of intracellular energy compounds, inorganic/biological amendments aimed at improving process performance, and sludge thermal pre-treatment.

Iron-loaded diatomite (Fe-DE) was developed as the innovative material to enhance anammox granular sludge (AnGS) and mainstream anammox performance. By adding Fe-DE with the Fe:DE ratio of 1:20 and the dosage of 3 g/L, the start-up period of mainstream anammox process was shortened from 29 d to 17 d and its nitrogen removal rate was increased from 0.234 kg N/(m·d) to 0.

Tumor hypoxia is one of key challenges in deep tumor photodynamic therapy (PDT), and how to fix this issue is attracting ongoing concerns worldwide. This work demonstrates dually fluorinated unimolecular micelles with desirable and stable oxygen-carrying capacity, high cellular penetration, and integrative type I & II PDT for deep hypoxic tumors. Dually fluorinated star copolymers with fluorinated phthalocyanines as the core are prepared through photoinitiated electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization under irradiation with NIR LED light at room temperature, followed by assembly into unimolecular micelles.
