“…Imides obtained from naphthalene anhydride as derivatives of 1,8-naphthalimide are widely used in medicine and biology, as compounds with high antitumor activity, cell dyes for bioimaging [ 12 , 13 , 14 ] and as ion detectors [ 15 ]. Most compounds containing 1,8-naphthalimide show absorption and emission in the visible spectrum region and good photo- and thermal-stability [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. 1,8-Naphthalimide derivatives in OLEDs and OPVs have been studied as electron-transporting materials [ 23 , 24 ], emitters [ 25 , 26 , 27 , 28 , 29 , 30 , 31 ], emission polymers additionally transporting electrons [ 32 ], as a host in the guest-host structure (acting as a matrix for the blue emitter) [ 9 ], and as green dopant [ 33 ].…”

In this paper, six novel symmetrical bis-(imino-1,8-naphthalimides) differing in core and N-substituent structure were synthesized, and their thermal (TGA, DSC), optical (UV-Vis, PL), electrochemical (DPV, CV) properties were evaluated. The compounds were stable to 280 °C and could be transferred into amorphous materials. Electrochemical investigations showed their ability to occur reductions and oxidations processes. They exhibited deep LUMO levels of about −3.22 eV and HOMO levels above −5.80 eV. The optical investigations were carried out in the solutions (polar and non-polar) and in films and blends with PVK:PBD. Bis-(imino-1,8-naphthalimides) absorbed electromagnetic radiation in the range of 243–415 nm and emitted light from blue to yellow. Their capacity for light emission under voltage was preliminarily tested in devices with an active layer consisting of a neat compound and a blend with PVK:PBD. The diodes emitted green or red light.

“…Organic semiconductors have gained considerable attention due to their potential applications in organic light-emitting diodes (OLEDs) [1][2][3][4], organic photovoltaics (OPVs) [5][6][7][8] and organic thin film transistors (OTFTs) [9,10]. In fabrication of the organic thin film transistors (OTFTs), conjugated polymers, oligomers, or small molecules are generally used as organic active layer.…”

“…On further acetylation, NIs 6a-f were obtained. These derivatives exhibited deep blue fluorescence in thin film state with excellent chromaticity and high stoke shifts [62,96]. The compounds were stable up to 260-280 °C and displayed quite higher electron affinities ranging from 3.31 to 3.43 eV, compared to the frequently used ETL materials.…”

“…Attractive derivatives can be created from NI skeleton, which can display strong fluorescent emission on irradiation, and their rich photophysical properties enable them to function as prime molecular entities for use in optoelectronic devices [59,60]. The presence of electron-deficient center in NI derivatives generally permit them to achieve high electron affinity, which validates their usage as HBL in OLEDs [61,62]. These molecules can have low reduction potentials [48,63,64] and wide energy gaps [65][66][67], and hence are profoundly studied as electron-deficient n-type organic semiconductors [68,69].…”

Organic light-emitting devices (OLEDs) have garnered significant research attention owing to their immense application prospects in leading technologies for full-color flat panel displays and eco-friendly solid-state lighting. They demonstrate exceptional features such as mercury-free construction, wide viewing angle, superior color quality and captivating flexibility. The requirements of light-emitting organic materials pertaining to high stability, lifetime and luminescence quantum yield, combined with the fabrication of devices with high performance efficiency, are highly challenging. Rational molecular design of 1,8-naphthalimide (NI) derivatives can offer quite promising results in achieving standard-light-emitting materials with a wide range of colors for OLED applications. This review is mainly focused on the synthesis and usage of varyingly substituted NI frameworks as luminescent host, dopant, hole-blocking and electron-transporting materials for OLEDs that emit not only red, orange, green and blue colors, but also function as white emitters, which can really have an impact on reducing the energy consumption. The future prospects that could be explored to improve the research in the highly promising field of OLEDs are also discussed. Graphical abstract
