Highly uniform supramolecular nano-films derived from carbazole-containing perylene diimide via surface-supported self-assembly and their electrically bistable memory behavior

For electrical memory applications, two perylenetetracarboxylic diimide (PDI) derivatives were synthesized and their surface-supported self-assembly behaviors were investigated.

Bis-naphthalimides bridged by electron acceptors: optical and self-assembly characteristics

The self-assembly of small organic molecules into molecular stacks plays a vital role in the construction of stable supramolecular structures.

Charge transport over multiple length scales in supramolecular fiber transistors: single fiber versus ensemble performance

Self-assembled organic fibers combine facile solution processing with the performance benefits of single crystals. Here, the first evidence is shown of band-like transport in an n-type solution-processed small molecule system, a limited role of shallow traps, and a single fiber electron mobility that is several orders of magnitude higher than that measured in fiber ensembles or spin-cast films.

Nickel nanoparticle chains inside carbonized polymer nanofibers: preparation by electrospinning and ion-beam irradiation

Novel organic-inorganic composite 1D nanostructures composed of carbonized conductive nanofibers and nickel nanoparticle chains were prepared by the combination of an electrospinning method from metal complex-containing polymer solutions and an ion-beam irradiation technique. The nickel nanoparticle chains were formed by self-assembly inside the carbonized nanofibers, which were characterized by STEM-HAADF observation and XPS spectroscopy. The existence of nickel complexes and the subsequent formation of nickel nanoparticles enhanced the electrical conductivities of carbonized nanofibers to reach above 0.5 S cm(-1) for the 6FDA-6FAP nanofibrous membrane containing 5.0 wt% Ni(acac)2 after ion-beam irradiation at an ion fluence of 1 × 10(16) ions per cm(2).
