Triphenylamine based conjugated microporous polymers for selective photoreduction of CO2 to CO under visible light

Organic π-conjugated polymers (CPs) have been intensively explored for a variety of critical photocatalytic applications in the past few years. Nevertheless, CPs for efficient CO2 photoreduction have been rarely reported, which is mainly due to

Tunable molecular configuration for significant enhancement of two-photon absorption based on novel octupolar benzoimidazole derivatives

Two novel octupolar molecules including benzoimidazole electron-accepting (A) branches and a triphenylamine electron-donating (D) center have been synthesized and characterized (p-ETBN and m-ETBN). Their photophysical and photochemical properties were investigated systematically including single-photon absorption, two-photon absorption (2PA) and charge transfer performance. Their 2PA properties have been investigated by the open aperture Z-scan technique, and the values of the 2PA cross section at 800 nm for p-ETBN and m-ETBN are ～300 GM and ～100 GM, respectively. Interestingly, both of them have the same D, A and π-conjugating units with only the different molecular configuration, the 2PA response of them differs by almost three times, which are found to be the different excited-state dipole moments and intramolecular charge-transfer. Our results reveal a new rule of molecular design for obtaining some excellent 2PA materials for their potential biophotonic and optoelectronic applications.

Ferrocene-based hyperbranched polymers: A synthetic strategy for shape control and applications as electroactive materials and precursor-derived magnetic ceramics

The stable sandwich structure and the excellent redox activity of ferrocene make it a ubiquitous component in organometallic systems. The introduction of a ferrocenyl unit into a polymer skeleton provides a good avenue towards novel materials for various applications in redox batteries, enantioselective catalysis, optical and magnetic switches, etc. Herein, we report a strategic design and synthesis of new ferrocene-based hyperbranched polymers, and demonstrate promising methods for their morphology control as spheres by direct coupling reactions and hollow polyhedra by a templating approach. Furthermore, task-specific applications targeted for their respective architectures are investigated in lithium ion batteries (LIBs) and water treatment, respectively. The spherical polymer used as an electroactive anode in LIBs has a high capacity of 755.2 mA h g-1, stable chargeable performance of over 200 cycles and superior rate capability. For comparison, the hollow counterpart shows a sharp increase of the specific surface area in the precursor-derived magnetic ceramics from 417 to 1195 m2 g-1, and the as-made material exhibits great potential for the rapid removal of trace amounts of pollutants in water with magnetic reusability.
