A new porous organic polymer has been prepared via copolymerization of divinyl-functionalized phosphoramidite ligand and tris(4-vinylphenyl)phosphine. The porous polymer was loaded with Rh(acac)CO2 to yield a supported Rh catalyst, which demonstrated good regioselectivity (l/b = 6.7-52.8) and high catalytic activity (TON up to 45.3 × 104) in hydroformylation of terminal and internal olefins. Remarkably, the heterogeneous catalyst can be reused at least 10 cycles without losing activity and selectivity in hydroformylation of 1-hexene.

In this paper, a novel fluorescent sensor 1 for selective and sensitive detection of cysteine was developed based on a complex between bi-8-carboxamidoquinoline derivative ligand (L) and Cu2+. The interaction of Cu2+ with the ligand causes a dramatic fluorescence quenching most likely due to its high affinity towards Cu2+ and a ligand?metal charge transfer (LMCT) process. The in situ generated L?Cu2 complex was utilized as a chemosensing ensemble for cysteine. In the presence of cysteine, the fluorophore, L, was released from L?Cu2 complex because of the strong affinity of cysteine to Cu2+ via the Cu?S bond, leading to the fluorescence recovery of the ligand. The proposed displacement mechanism was confirmed by the results of mass spectrometry (MS) study. Under optimized conditions, the recovered fluorescence intensity is linear with cysteine concentrations in the range 1 × 10?6 mol/l to 8 × 10?6 mol/l. The detection limit for cysteine is 1.92 × 10?7 mol/l. Furthermore, the established method showed a highly sensitive and selective response to cysteine among the 20 fundamental alpha-amino acids used as the building blocks of proteins, after Ni2+ was used as a masking agent to eliminate the interference of His. The proposed sensor is applicable in monitoring cysteine in practical samples with good recovery rate.

A dynamic axially chiral BIPHEP-ligand with 3,5-dichlorobenzoyl amide selector units for non-covalent binding of phenylalanine derivatives has been developed. Interaction studies in solution were performed with rhodium(i) complexes under exclusion of the metal being involved in binding. (Rax, SPhe) and (Sax, SPhe) adducts were observed as significantly separated species in NMR spectroscopy.

Phenol was removed from water by horseradish peroxidase-catalyzed polymerization. Five dimeric and one trimeric products from the reaction were identified in the aqueous solution. A peroxidase inactivation model for the reaction in the presence of poly(ethylene glycol) (PEG) was proposed, and the inactivation rate constant was found to have a logarithmic relationship with the ratio of PEG to enzyme doses. The three dimers were the substrates of peroxidase, and their conversion could also be depicted with a first-order model with respect to the dimer concentrations. The predominant polymerization bonds in the products may be the oxygen-para connection whereas the ortho-ortho connection would hardly be found in the higher oligomers. (from Authors)

The reaction of 1 with several kinds of aldehydes in the presence of Triton B or NaH in THF solvent revealed that these reagents are useful for the synthesis of Z-unsaturated esters. Among the reagents examined, ethyl(di-o-tolylphosphono)-, [bis(o-ethylphenyl)phosphonol-, and [bis(o-isopropylphenyl)phosphono]acetates (1k-m) were found to be the most effective, giving Z-unsaturated esters with 93-99% selectivity.

Brown algae have an important role in marine environments. With respect to their broad distribution and importance for the environment and human use, brown algae of the order Fucales in particular became a model system for physiological and ecological studies. Thus, several fucoids have been extensively studied for their composition on the molecular level. However, research of fucoid physiology and biochemistry so far mostly focused on the adult algae, so a holistic view on the development of these organisms, including the crucial first life stages, is still missing. Therefore, we employed non-targeted metabolite profiling by gas chromatography coupled to mass spectrometry to create a non-biased picture of the early development of the fucoid alga Fucus vesiculosus. We found that embryogenic physiology was mainly dominated by a tight regulation of carbon and energy metabolism. The first dramatic changes of zygote metabolism started within 1 h after fertilization, while metabolism of 6?9 days old embryos appeared already close to that of an adult alga, indicated by the intensive production of secondary metabolites and accumulation of mannitol and citric acid. Given the comprehensive description and analysis we obtained in our experiments, our results exhibit an invaluable resource for the design of further experiments related to physiology of early algal development.

Three novel polymerizable anion receptors based on boric acid esters have been synthesized. The addition of these monomers appreciably enhanced the ionic conductivity of certain electrolyte solutions comprised of an aprotic organic solvent of low polarity and a lithium salt of low dissociation ability. Analysis of the viscosity and pulse-field-gradient spin-echo (PGSE) NMR results in association with the ionic conductivity data revealed that the conductivity enhancement originated from the increase in the degree of dissociation, resulting from the addition of these anion receptors. The 11B NMR spectra of dimethoxyethane electrolyte solutions with added boric acid ester monomers substantiated the finding that the ionic dissociation was facilitated by strong interaction between the Lewis-acidic anion receptor and Lewis-basic anions. The polymerizable anion receptor of the catechol borate derivative was cross-linked with a polyether macromonomer containing different lithium salts. The ionic conductivity could be correlated with glass transition temperatures of the polymer electrolytes by the WLF equation. The ionic conduction behavior of the boron polymer electrolytes was compared with that of the reference polymer electrolytes, and the lithium cation transference number was clarified to be higher for the former. The polymer electrolytes showed similar conduction behavior to that of the electrolyte solutions containing the anion receptor monomers.
