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

High surface area contorted conjugated microporous polymers based on spiro-bipropylenedioxythiophene

Conjugated polymers derived from thiophene or 3,4-ethylenedioxythiophene derivatives have been widely investigated for use in organic thin-film transistors and organic photovoltaic devices. We describe here the synthesis of a series of conjugated microporous polymers formed by reaction of spirobis( 2,5-dibromopropylenedioxythiophene) with one of three di- or triethynyl monomers. These polymers have surface areas up to 1631 m2/g and exhibit significant microporosity, suggesting possible applications in the fields of organic electronics or optoelectronics.

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.

Metallated Graphynes as a New Class of Photofunctional 2D Organometallic Nanosheets

Two-dimensional (2D) nanomaterials are attracting much attention due to their excellent electronic and optical properties. Here, we report the first experimental preparation of two free-standing mercurated graphyne nanosheets via the interface-assisted bottom-up method, which integrates both the advantages of metal center and graphyne. The continuous large-area nanosheets derived from the chemical growth show the layered molecular structural arrangement, controllable thickness and enhanced π-conjugation, which result in their stable and outstanding broadband nonlinear saturable absorption (SA) properties (at both 532 and 1064 nm). The passively Q-switched (PQS) performances of these two nanosheets as the saturable absorbers are comparable to or higher than those of the state-of-the-art 2D nanomaterials (such as graphene, black phosphorus, MoS2, γ-graphyne, etc.). Our results illustrate that the two metallated graphynes could act not only as a new class of 2D carbon-rich materials, but also as inexpensive and easily available optoelectronic materials for device fabrication.

Synthesis of alkynes under dry reaction conditions

An easy synthetic method was developed under dry reaction conditions for the preparation of terminal alkynes from 1,1-dibromoalkenes and in the presence of succinimide which acts as a nucleophile and proton donor. It was demonstrated with the synthesis of a broad spectrum of terminal alkynes and extended to synthesize internal alkynes under tandem reaction conditions.

Optical properties of triphenylamine decorated with naphthalimide

A propeller conformed triphenylamine molecule was decorated with naphthalimide. The two fluorophores were bonded with alkynyl bridge unit, which conjugates the two fragments. The resulting compound was fully characterized. Several solvents were used to investigate its absorption and emission behavior with the solvent polarity variation from weak to strong. The quantum yield increased with the increasing of solvent polarity. It is also highly emissive in film and in a solid with significant emission shift toward longer wavelength, reaching to 544 and 593?nm, respectively. The underlying signal mechanism was interpreted by the HOMO/LUMO potentials based on TDDFT calculations.

Hollow and microporous triphenylamine networks post-modified with TCNE for enhanced organocathode performance

Hollow microporous triphenylamine networks (H-MTPN) were post-modified with tetracyanoethylene (TCNE) to generate tetracyanobutadiene moieties in H-MTPN-TCNE. The H-MTPN-TCNE showed the improved electrochemical performance of cathode materials for lithium ion batteries, compared to the original H-MTPN.
