Unlike normal ACQ-to-AIE conversion by the introduction of aromatic rotors accompanying the realization of a twisted conformation and a prolonged π-system, in this communication, the adjustment of the flexible chains can reach this point with the tunable packing modes while the original π-system core and related properties of the aromatic naphthalene diimide remain nearly unchanged, providing an alternative approach for the inhibition of unwanted π-π stacking.

The final outcomes of supramolecular assembly are determined by the pathways and the formation of intermediates during the assembly process. We studied pathway complexity involving two consecutive pathways in supramolecular polymerization of naphthalene-diimide (NDI) derivative molecule. Depending on preparation methods anisotropic aggregates of J-type nanorods (Agg I) or more flexible H-type nanofibers (Agg II) are obtained from the identical initial state in solution of methyl cyclohexane (MCH) or MCH/CHCl3 mixtures.

Organic mixed ionic-electronic conductors (OMIECs) are crucial in defining the operational modes and performance of organic electrochemical transistors (OECTs). However, studies on the design and structure-performance correlations of small-molecule n-type OMIECs remain scarce. Herein, we designed and synthesized a series of naphthalene diimide (NDI)-based n-type small molecules by extending π-conjugation and increasing the number of electron-withdrawing groups, achieving performance optimization and even changes in operational modes through structural regulations.

Electron donor tetrathiafulvalene (TTF) and electron acceptor naphthalene diimide (NDI) derivatives were used to synthesize a 3D Zn-TTF/NDI-MOF. Multiple redox active sites and charge transfer endow the pristine MOF anode with excellent rate behavior and long term cycling performance (with an average specific capacity of 956 mA h g at 1 A g over 600 cycles). This study highlights the great potential of elaborately-designed MOFs for developing efficient anode materials.

Aromatic diimides such as naphthalene diimide (NDI) and pyromellitic diimide (MDI) are important building blocks for organic electrode materials. They feature a two-electron redox mechanism that allows for energy storage. Due to the smaller size of MDI compared to NDI its theoretical capacity is higher.

Designing the architecture of donor-acceptor (D-A) pairs is an effective strategy to tailor the electronic structure of conjugated macrocycles for optoelectronic devices. Herein, we present the synthesis of three D-A nanohoops ( = 7, 8, 9) containing a naphthalene diimide (NDI) unit as an acceptor and []cycloparaphenylenes ([]CPPs) moieties as donors. The D-A characteristics of were substantiated through absorption and fluorescence spectroscopic studies, electrochemical investigations, and computational analysis.
