Pillararene-enriched linear conjugated polymer materials with thiazolo[5,4-d]thiazole linkages for photocatalysis

A heteroatom-doped conjugated polymer with tunable bandgap is synthesized using pillararenes as the electron-richC2symmetric nodes and thiazolo[5,4-d]thiazole as the electron-deficient linkage. The influence of pillararenes in regulating the band structure and photogenerated charge carrier transportation for photocatalytic environmental contaminant degradation has been revealed.

Fulleropillar[4]arene: The Synthesis and Complexation Properties

A multihydroquinone ether dialdehyde derivative 2 was incidentally obtained through an unexpected ring opening of pillar[4]arene[1]quinone 1. And the Prato reaction of 2 with [60]fullerene led to [60]fullerene bisadducts, from which trans-4 cyclic regioisomer 3 was isolated and characterized. The fulleropillar[4]arene 3 showed a larger cavity and can accommodate a viologen derivative C12V2+with a much stronger affinity than permethyl pillar[5]arene (MP5) and pillar[4]arene[1]quinone 1.

All-solid-state lithium organic battery with composite polymer electrolyte and Pillar[5]quinone cathode

The cathode capacity of common lithium ion batteries (LIBs) using inorganic electrodes and liquid electrolytes must be further improved. Alternatively, all-solid-state lithium batteries comprising the electrode of organic compounds can offer much higher capacity. Herein, we successfully fabricated an all-solid-state lithium battery based on organic pillar[5]quinone (C35H20O10) cathode and composite polymer electrolyte (CPE). The poly(methacrylate) (PMA)/poly(ethylene glycol) (PEG)-LiClO4-3 wt % SiO2 CPE has an optimum ionic conductivity of 0.26 mS cm-1 at room temperature. Furthermore, pillar[5]quinine cathode in all-solid-state battery rendered an average operation voltage of ～2.6 V and a high initial capacity of 418 mAh g-1 with a stable cyclability (94.7% capacity retention after 50 cycles at 0.2C rate) through the reversible redox reactions of enolate/quinonid carbonyl groups, showing favorable prospect for the device application with high capacity.

Conjugated Macrocycle Polymer Nanoparticles with Alternating Pillarenes and Porphyrins as Struts and Cyclic Nodes

Conjugated macrocycle polymers (CMPs) integrated using the macrocyclic confinement effect make imposing restrictions feasible on the growth of metal nanoparticles with confined size and high dispersion. For a proof-of-concept exploration, a novel nanoscale CMP is reported, denoted as DMP[5]-TPP-CMP, comprising two representative types of macrocyclic compounds, i.e., pillararene and porphyrin, as alternating strut/node components in the skeleton. With abundant anchoring sites, CMP implanted with Pd nanoparticles (Pd@DMP[5]-TPP-CMP, Pd@CMP for short) is successfully obtained through a simple post-treatment, exhibiting remarkable catalytic activity in Suzuki–Miyaura coupling (SMC) and nitrophenol reduction. The as-prepared Pd@CMP material shows favorable performance in expediting the process of SMC with an appreciable yield even under mild conditions, as well as in facilitating the electron transfer process from borohydride to nitrophenol through metal–hydride complex to produce aminophenol with a very short transformation time of 3 min and superior apparent kinetic rate constant k app of 1.9 × 10?2 s?1, higher than most palladium supports. Significantly, this multifunctional Pd@CMP composite material not only enriches the family of CMPs, but also sheds light on the development of green catalysts with excellent stability and easy recyclability without deactivation.

Synthesis of pillar[5]arene dimers and their cooperative binding toward some neutral guests

Three pillar[5]arene dimers, bridged by a flexible aliphatic chain (H1) or a relatively rigid phenylene unit (H2 and H3), were synthesized, with the possible synthetic strategies being discussed. The dimers could significantly enhance the binding affinities toward neutral model substrates in comparison with monomeric 1,4-dimethoxypillar[5]arene (H4) through the cooperative binding of two pillar[5]arene moieties. The molecular binding ability and selectivity are discussed from the viewpoints of the size/shape-fit concept and multiple recognition mechanism.
