Polyesters, especially polyethylene terephthalate (PET), are widely used in plastic bottles and clothing fibers because of their stability cost-effectiveness. Upcycling waste polyesters into value-added materials not only solves the environmental crisis but also realizes significant economic interests. Here, we report a step-economic two-step catalytic process for upcycling polyester materials, specifically PET, 1,4-cyclohexanedimethanol (CHDM), an essential monomer functional key feedstock...

The photoreduction dehalogenation reaction triggered by NADH to form active carbon radicals was firstly applied in PDT tackle hypoxia associated problems.

2,5-Furandicarboxylic acid (FDCA), which is currently prepared by catalyzing the oxidation of 5-hydroxymethylfurfural (HMF), a biobased platform compound with broad market prospects. Herein, detailed free-radical chain reaction mechanism consisting both main and side pathways was proposed to describe liquid-phase air process 2,5-furandicarboxylic over Co/Mn/Br catalyst. The higher reactivity hydroxymethyl group than aldehyde for HMF first explained according retardation effect alcohols on...

5-Hydroxymethylfurfural (HMF) is a crucial biobased compound for synthesizing chemicals and biofuels, but the direct conversion of glucose to HMF suffers low yield purification problems. In this paper, cheap efficient deep eutectic solvent (DES) choline chloride–chromium chloride (ChCl–CrCl3·6H2O) was developed convert other carbohydrates HMF. High yields 70.2, 78.6, 72.6, 71.7% were achieved from glucose, fructose, high fructose corn syrup, sucrose, respectively. The DES ChCl–CrCl3·6H2O...

A Ru-anthraquinone dyad with triple functions of PACT, photoredox catalysis and PDT upon red light irradiation was reported.

A two-photon excited "Ping-Pong" type energy transfer process is for the first time disclosed in a pyrene-modified Ir(iii) cyclometalated complex. The transfer, from singlet state of 4-(pyren-1-yl)-tpy (tpy-py) unit to moiety and then back again triplet tpy-py unit, enhances both absorption cross sections oxygen quantum yield complex, dramatically boosts its photodynamic activity vitro 3D multicellular spheroids.

5-Hydroxymethylfurfural (HMF) is a high-value biomass-derived platform chemical derived from renewable biomass, which great alternative to petroleum-based chemicals; however, it cannot be produced on large scale at present because of the limitation low HMF yield and costly production. In this work, an experimental study one-pot production glucose in acetone–water solvent was conducted. The effects inorganic salts (in specific, NaCl) miscible solvents were studied could affect phase structure...

Converting carbohydrates to 5-hydroxymethylfurfural (HMF) is an important goal for biorefinery. Although various deep eutectic solvents (DESs) have been reported HMF production, the field lacks systematic research on effect of cations and anions effective catalytic system converting concentrated carbohydrates. Here, 12 kinds DESs containing four six were systematically evaluated tetraethylammonium bromide (TEAB) was confirmed as most DES, which provided yields 90 76% from fructose glucose,...

A versatile Ru(<sc>ii</sc>) complex with self-reporting ligand photo-dissociation and efficient two-photon excited synergistic PACT PDT abilities was designed studied.

The replacement of a pyridine group [Co(TPA)Cl]⁺ by quinoline or an isoquinoline was observed to have opposite effect on H₂ evolution.

Gold-catalyzed oxidative esterification of 5-hydroxymethylfurfural (HMF) under basic conditions is a promising process to produce dimethyl-2,5-furan dicarboxylate (DMFD). However, it has been overlooked that the DMFD readily hydrolyzes in presence soluble bases. Herein, we report solid base-supported gold catalysts for base-free conversion HMF. The catalysts' sites (BSs) were found facilitate aldehydes and oxidation alcohols aldehydes. Moreover, properties BSs strongly influenced catalyst...

The use of cellulose as a substitute for fossil resources has gained significant attention due to the depletion nonrenewable energy sources and increasing potential environmental crisis. selective hydrogenolysis C3 polyols, namely, 1,2-propanediol glycerol, is one attractive biomass depolymerization utilization pathways. However, coordinating sugar isomerization retro-aldol condensation remains challenge. In this paper, we manipulate hydrogen spillover behavior Pd–Mo/TiO2 catalyst by tuning...

Abstract Photoactivated chemotherapy (PACT) has appealing merits over traditional as well photodynamic therapy (PDT) by virtue of its spatial and temporal control on drug activity oxygen‐independent mechanisms action. However, the short photoactivation wavelengths, e.g., visible light–activated Ru(II)‐based PACT agents, limit clinical application severely. In this work, a facile construction supramolecular nanoparticles from poly(ethylene glycol) (PEG)‐modified [Ru(dip) 2 (py‐SO 3 )] +...

Photoacid generators (PAGs) are finding increasing applications in spatial and temporal modulation of biological events vitro vivo. In these applications, large pH jumps at low PAG concentrations great importance to achieve maximal expected manipulation but minimal unwanted interference. To this end, both high photoacid quantum yield capacity essential, where the refers proton number that a molecule can release. Up now, most PAGs only produce one for each molecule. work, hydrolysis reaction...
