Abstract Driven by recent advances in rapid multiphoton single‐focus 3D laser nanoprinting, multifocus variants thereof, and projection‐based the necessary average total powers from femtosecond oscillators or even amplified systems have exceeded Watt level. Aiming at ever faster printing, there exist two options: Using yet more powerful lasers searching for sensitive photoresists allowing higher speeds comparable lower power levels. Here, altogether than 70 different literature a few new...
The careful mapping of photoinduced reversible-deactivation radical polymerizations (RDRP) is a prerequisite for their applications in soft matter materials design. Here, we probe the wavelength-dependent behavior photochemically induced atom transfer polymerization (ATRP) using nanosecond pulsed-laser (PLP). photochemical reactivities at identical photon fluxes methyl acrylate terms conversion, number-average molecular weight, and dispersity resulting polymers are mapped against absorption...
The market of epoxy resin-based adhesives is constantly growing in automotive, electronics and healthcare industries thanks to their unique features such as high bonding strength, durability, corrosion resistance. In this work, alternative sustainable vitrimer adhesives, containing from 20 50 wt% lignin microparticles, were prepared epoxidized linseed oil (ELO) a boronic ester dithiol crosslinker (DBEDT), the absence solvents catalysts. addition unmodified commercial Kraft composites...
A family of imine-based nonheme iron(II) complexes (LX)2Fe(OTf)2 has been prepared, characterized, and employed as C-H oxidation catalysts. Ligands LX (X = 1, 2, 3, 4) stand for tridentate imine ligands resulting from spontaneous condensation 2-pycolyl-amine 4-substituted-2-picolyl aldehydes. Fast quantitative formation the complex occurs just upon mixing aldehyde, amine, Fe(OTf)2 in a 2:2:1 ratio acetonitrile solution. The solid-state structures (L1)2Fe(OTf)(ClO4) (L3)2Fe(OTf)2 are...
Eco-friendly blends of polylactic acid (PLA)/polyhydroxybutyrate (PHB) have been developed with the use a sustainable plasticizer, namely epoxidized soybean oil methyl ester (ESOME). While PLA, PHB, and their are highly valued for bio-origin compostability at end lifecycle, enhancing flexibility improved processability broadening range applications is an ongoing challenge. For this reason, we present formulation PLA/PHB varying ESOME concentrations, processed by extrusion compression...
RAFT copolymerization of 4-[(hydroxyimino)aldehyde]butyl methacrylate with OEGMA<sub>475</sub> and first assessment photoisomerization thermal behavior the copolymers in solution.
Conjugated enynes as well cyclic nitronates are crucial building blocks for numerous natural products and pharmaceuticals. However, so far, no common metal‐free synthetic route to both conjugated has been reported. Herein, in situ NMR, labelling studies theoretical calculations were combined investigate the mechanism of unusual triple bond formation towards enynes. Starting from nitroalkene dimers, first an isoxazolidine‐2,5‐diol derivative is formed central intermediate. From this,...
In the context of our research on stimuli-responsive polymers bearing 2-(hydroxyimino)aldehyde (HIA) group, we have explored photochemical behavior and physicochemical properties a number HIAs. Interpretation experimental data is supported by quantum mechanical calculations. HIAs are expected to undergo photoisomerization, chelate metal ions, yield hydrogen-bonded dimers or oligomers, exhibit relatively low pKa s, form >C=NO. radicals through OH hydrogen abstraction oxidation oximate ion....

Aqueous formulations of self-assemblies containing the nucleobase analogue 2,6-diacylaminopyridine have been obtained by seeded RAFT polymerization in water with different morphologies depending on conditions.
The Cover Feature shows a machine that generates conjugated enynes and cyclic nitronates within one-pot reaction from simple nitroalkenes. towards both products shares common pathway deviates or depending on the conditions. By adjusting additive base, selectivity between can be controlled. NMR monitoring in combination with theoretical calculations helped to elucidate mechanism products. This stands as symbol for flasks NMR-tubes which reactions were carried out. More information found Full...
Recently, the necessary average total laser power for rapid multi-photon multi-focus applications has exceeded Watt level. To enable even faster 3D printing, we have developed new sensitive photoresists by adding co-initiators to commonly used standard systems. We yet exceed these advances in sensitivity using a novel photoresist system based on modified benzylidene ketone photoinitiator, making it very attractive advanced nanoprinting. compare our original results more than 70 different...
