Summary: This work focuses on the synthesis of poly(pyrazolopyridine)s through a three-component Hantzsch reaction. The study first aimed to determine the suitable experimental conditions for synthesizing an analytically pure pyrazolopyridine heterocycle model compound. Specific difunctional precursors were then designed and synthesized, and poly(pyrazolopyridine)s were successfully synthesized through multicomponent polycondensation reaction. Some physico-chemical characterizations of these new macromolecular structures are described.

Summary: Gas permselectivity of novel PPL-silica hybrid membranes, obtained through thermal rearrangement and sol-gel reaction, was investigated. The gas permeability of neat PPL membranes improved with higher rearranged temperature due to increased fractional free volume. The H-2/CH4 and CO2/CH4 separation abilities of the PPL-silica hybrid membranes improved as silica content increased, approaching the upper bound trade-off lines. These enhanced separation abilities were attributed to the cooperative effect of high fractional free volume derived from PPL conversion and expansion-suppressed free volume elements at the polymer-silica interfaces.

Summary: Modifying structures and doping in g-C3N4 quantum dots have been proven effective in tuning their properties. Functionalizing tri-s-triazine and tri-nitro tri-s-triazine structures with hydrogen improves their planarity and reactivity, with additional B doping further enhancing these properties. The study suggests that highly reactive sheets can potentially be used for removing hazardous ions and molecules from industrial waste.

Summary: Cyclohexanone-formaldehyde resin and acetophenone-formaldehyde resin were modified in situ with sodium alendronate and nanocomposites containing sepiolite and montmorillonite were successfully produced. The modified resins and their nanocomposites were used to produce reactive non-toxic fire retardant rigid polyurethane foam, with good flame retardant properties and self-extinguishing characteristics observed in testing. The study demonstrated the potential for using alendronic acid-modified resins and nanoclays for developing flame retardant polyurethane materials.

Summary: A post-synthetic modification strategy was used to construct superhydrophilic tCOF-based photocatalysts by growing FeOOH clusters on TaTz COF. The optimized TaTz-FeOOH (1%) shows excellent photocatalytic performance, with a 12-fold increase in the photocatalytic degradation rate of rhodamine B and a degradation rate of 99% after 5 cycles. This study provides a new approach for developing hydrophilic COF-based functional materials for practical applications.

Summary: Nonstoichiometric polyaddition was achieved through Co-catalyzed hydroarylation of diyne monomers with excess 1-(2-pyrimidinyl)pyrrole. The 2-pyrimidinyl substituent acted as a directing group, facilitating intramolecular catalyst transfer and yielding poly(arylenevinylene)s with alkyne terminals and high molecular weight.

Summary: Tri-s-triazine heterostructures were prepared using g-C3N4, melem, MTA, and graphene as precursors. The heterostructures were characterized using various techniques and the formation of reactive species was verified. Hydrogen evolution reactions were conducted and the results showed that the increase in MTA content enhanced the reaction. The modulation of MTI content in intramolecular tri-s-triazine heterostructures is a promising approach for producing materials for photo- and electrocatalysis.

Summary: A facile strategy to construct heteroatom-induced interfaces and develop titanium-organic frameworks (MOF-902) @ thiophene-based covalent triazine frameworks (CTF-Th) nanosheets S-scheme heterojunctions with controllable oxygen vacancies (OVs) is reported. The enhanced interfacial charge separation and transfer induced by moderate OVs in the pre-designed S-scheme nanosheets was validated using various analytical techniques. The heterostructures exhibited improved efficiency in photocatalytic reactions and an extended scope of substrates, outperforming state-of-the-art photocatalysts.

Summary: This study outlines the fabrication and characterization of pamidronate (PDS) embedded nanofibrous scaffolds based on polycaprolactone/polycaprolactone-polyethyleneglycol-polycaprolactone (PCL/CEC) blends for osteoporotic bone defect management. The electrospinning technique was utilized to fabricate PDS-loaded scaffolds, and the effect of PDS on the blends was evaluated in terms of surface morphology, wettability, biodegradability, and in vitro cytocompatibility. The results showed that the PCL/CEC-PDS scaffolds had a fibroporous architecture, appropriate mechanical properties, and the ability to support cell growth, indicating their potential for managing osteoporotic bone defects.
