3D Orientational Control in Self-Assembled Thin Films with Sub-5 nm Features by Light

Nickmans, Koen; Bögels, Gerardus M.; Sánchez‐Somolinos, Carlos; Murphy, Jeffrey N.; Leclère, Philippe; Voets, Ilja K.; Schenning, Albertus P. H. J.

While self-assembled molecular building blocks could lead to many next-generation functional organic nanomaterials, control over the thin-film morphologies to yield monolithic sub-5 nm patterns with 3D orientational control at macroscopic length scales remains a grand challenge. A series of photoresponsive hybrid oligo(dimethylsiloxane) liquid crystals that form periodic cylindrical…

Dimensional Control and Morphological Transformations of Supramolecular Polymeric Nanofibers Based on Cofacially-Stacked Planar Amphiphilic Platinum(II) Complexes

Robinson, Matthew E.; Nazemi, Ali; Lunn, David J.; Hayward, Dominic W.; Boott, Charlotte E.; Hsiao, Ming-Siao; Harniman, Robert L.; Davis, Sean A.; Whittell, George R.; Richardson, Robert M.; De Cola, Luisa; Manners, Ian

Square-planar platinum(II) complexes often stack cofacially to yield supramolecular fiber-like structures with interesting photophysical properties. However, control over fiber dimensions and the resulting colloidal stability is limited. We report the self-assembly of amphiphilic Pt(II) complexes with solubilizing ancillary ligands based on polyethylene glycol . The…

Opposing Phase-Segregation and Hydrogen-Bonding Forces in Supramolecular Polymers

Chen, Senbin; Yan, Tingzi; Fischer, Matthias; Mordvinkin, Anton; Saalwächter, Kay; Thurn‐Albrecht, Thomas; Binder, Wolfgang H.

Phase segregation between different macromolecules and specific weak interactions are the basis of molecular organization in many biological systems, which are held together by attractive hydrogen bonds (H-bonds) and dissociated by phase segregation. We report significant changes in the association behavior of covalent H-bonds by the phase of attached polymer…

Coscia, Marta Gina; Bhardwaj, Jyoti; Singh, Nandita; Santonicola, M. Gabriella; Richardson, Robert; Thakur, Vijay Kumar; Rahatekar, Sameer

We report a novel manufacturing method for bio renewable regenerated cellulose fibres modified with curcumin, a molecule is known for its medicinal properties. Ionic liquid namely 1-Ethyl 3-Methyl Imidazolium diethyl phosphate (emim DEP) was found to be capable of dissolving cellulose as well as curcumin. Regenerated cellulose/curcumin composites fibres with…

Surface-initiated reversible addition-fragmentation chain transfer polymerization of chloroprene and mechanical properties of matrix-free polychloroprene nanocomposites

Zheng, Yang; Abbas, Zaid M.; Sarkar, Amrita; Marsh, Zachary; Stefik, Morgan; Benicewicz, Brian C.

RAFT polymerization and surface-initiated RAFT polymerization (SI-RAFT) of chloroprene was studied. The SI-RAFT polymerization rate of chloroprene was found to be slower than free solution RAFT polymerization, and further regulated by the graft density of grafted polymers. The resulting polychloroprene-grafted silica nanoparticles were directly crosslinked to obtain matrix-free polychloroprene…

Surface imperfections in perovskite films upon crystallization may trigger trap-assisted non-radiative recombination which is a dominant recombination mechanism that potentially restricts the performance of solar devices. In this work, 2D alkylammonium halide perovskites are formed on the 3D perovskite structure to passivate interfacial defects and vacancies and enhance moisture tolerance.…

Silicon (Si) has been regarded as one of the most promising anodes for next-generation lithium-ion batteries (LIBs) due to its exceptional capacity, appropriate voltage profile, and reliable operation safety. However, poor cyclic stability and moderate rate performance have been critical drawbacks to hamper the practical application of Si-based anodes. It…

Extended LaMer Synthesis of Cobalt-Doped Ferrite

Fellows, B. D.; Sandler, S.; Livingston, J.; Fuller, K.; Nwandu, L.; Timmins, S.; Lantz, K. A.; Stefik, M.; Mefford, O. T.

Nonstoichiometric cobalt ferrite nanoparticles have drawn interest in magnetically mediated energy delivery due to their high magnetocrystalline anisotropy and their high peak loss frequency. The use of an extended LaMer synthesis allows for size control of the doped particles up to a threshold core diameter of 18 nm. Above this…

Li4Ti5O12 (LTO) is regarded as a promising lithium-ion battery anode due to its stable cyclic performance and reliable operation safety. The moderate rate performance originated from the poor intrinsic electron and lithium-ion conductivities of the LTO has significantly limited its wide applications. A facile scalable synthesis of hierarchical Li4Ti5O12/C nanohybrids…

Organic–inorganic perovskites demonstrate great potential for optical applications due to their intriguing optical and optoelectronic properties. Dedicated efforts have been carried out to understand the energy landscape and charge carrier mobilities for perovskite materials. In order to further boost these materials toward large-scale applications, an alternative “bottom-up” route for the…
