Summary: Three novel amylose and cellulose phenylcarbamate derivatives were synthesized as chiral fluorescent sensors, showing good enantioselective properties. These derivatives demonstrated high efficiency in chiral fluorescent sensing for important chiral drug intermediates and also displayed good resolution powers as chiral stationary phases in high-performance liquid chromatography. The excitation-dependent chiral fluorescent sensing mechanism was found to be different from chromatographic enantioseparation.

Summary: Two novel cellulose and amylose derivatives with bulky tris(2-benzothienylformate) pendants were rapidly synthesized by one-step esterification. The fluorescence sensing performance of these derivatives, as well as other benzothienyl- or benzofuranyl-phenylcarbamates of cellulose and amylose, was carefully evaluated for the detection of Fe3+ ions. The derivatives exhibited high sensitivity and selectivity towards Fe3+ ions, and also demonstrated good reversibility and anti-interference ability in the presence of other metal ions.

Summary: This study investigates enhancing the separation performance of cellulose acetate (CA) by incorporating ionic liquid-like pendants. The experiments show that with increasing HEDMA content, the permeability of CO2 and N-2 decreases, while the selectivity of CO2/N-2 initially decreases and then gradually increases. This suggests potential for further improvements by altering interactions between the polymer network and permeating CO2 molecules.

Summary: Porous 3D hybrid materials (SWCNT/CoPc and SWCNT/ZnPc) were prepared and characterized for detecting gaseous H2S at low concentrations. The sensor response of SWCNT/CoPc was about 4 times higher than SWCNT/ZnPc, which correlated with the larger number of CoPc molecules on the SWCNT surface. The calculated LOD of H2S was 18 ppb for SWCNT/CoPc and 65 ppb for SWCNT/ZnPc.

Summary: The study visualized the helical structures of poly(diphenylacetylene)s bearing optically active substituents linked through amide bonds and with a helicity memory using atomic force microscopy. The polymers self-assembled into an ordered 2D monolayer on highly oriented pyrolytic graphite upon exposure to solvent vapor, with the helical pitch and handedness (right- and left-handed) directly revealed at molecular resolution for the first time.

Summary: This study investigated the in-situ coating of carbon electrodes with citric acid-crosslinked cellulose derivatives for improved sorption capacity towards metal ions, showing promising results for heavy metal sequestration applications. The electrodes coated with the crosslinked cellulose derivatives exhibited stripping voltammetry peaks for Pb, Cd, and Cu, as well as reversible changes in electrochemical impedance after metal ion absorption. The detection limit for Pb2+ sensing was found to be 0.39 mg L-1 with a sensitivity of 9.91 μA L mg(-1), suggesting the potential for cheap and sustainable heavy metal sensors.

Summary: Gasotransmitters are a promising and less-explored area of research, as they have significant biological impacts and can act as both friend and foe in mammalian systems. This review highlights the physiological and pathophysiological roles of these endogenous gas transmitters, as well as their synergistic interactions. It also discusses various detection approaches, with a focus on the usage of 1,8-naphthalimide as a fluorescent probe for the detection and monitoring of these small signaling molecules.

Summary: The study found that temperature-responsive polyaspartamide derivatives without hydroxyl groups exhibited temperature responsiveness under acidic, neutral, or alkaline conditions. The critical solution temperature values of these derivatives could be controlled by adjusting the pH, affecting their temperature-responsive behavior.

Summary: Fluorescent and magnetic nanoparticles have been widely used for various (bio)applications, with methods for their synthesis often requiring complex modifications that result in low particle yields. This study presents a simple and scalable method for magnetic modification of cellulose-based fluorescent particles using magnetite nanoparticles. The resulting bifunctional particles maintain their pH sensitivity, optical properties, and can be manipulated by an external magnetic field, showing promise for large-scale production and potential biomedical applications.
