Recent progress in the usage of tetrabromo-substituted naphthalenetetracarboxylic dianhydride as a building block to construct organic semiconductors and their applications

Abstract

Tetrabromo-substituted naphthalenetetracarboxylic dianhydrides (TBNDA) have attracted considerable attention in constructing organic semiconductors (OSCs) for diverse applications in the past decade. A series of synthetic strategies have been developed to modify...

Variable Learning‐Memory Behavior from π‐Conjugated Ligand to Ligand‐Containing Cobalt(II) Complex†

“…As displayed in Scheme 1, the complex CoNIPy was successfully synthesized through forming coordination bonds between the core organic NIPy ligand and transition metal Co(II) atom. Four extra design highlights can also be summarized as follows: (a) NIPy with excellent conjugation structure possesses both electron‐ donating (Donor) and electron‐withdrawing (Acceptor) groups, ensuring the potential charge‐transfer (CT) ability in the OSMCs; [ 17 ]…”

“…[12][13][14] By contrast, organic small molecule complexes (OSMCs) show unique advantages of the specific molecular constitution and readily comprehensible metal-to-ligand charge-transfer (LMCT) process. [15][16] Thus, the strategy of transforming organic small molecules to OSMCs exhibits the potential to resolve these intrinsic issues. Notably, if possible, some noble metals (such as Rh(III), Ir(III), Pt(II), Au(III)) acting as the central metal ions are avoided in practical applications, due to their high production cost.…”

Incorporation of hydrogen‐bonding units into polymeric semiconductors toward boosting charge mobility, intrinsic stretchability, and self‐healing ability

“…Design strategies for performance improvement usually start from these two aspects: design of conjugated units for main chain and side chain engineering. As for main chain engineering, exceptionally successful building blocks such as diketopyrrolopyrrole (DPP), isoindigo, and naphthalenediimide have been studied extensively 23–33 . As for side chain engineering, the structures of side alkyl chains with regard to the branching site and the lengths of side chains have been usually finely tailored 9,34–37 .…”

Our research progress in heteroaggregation and homoaggregation of organic π‐conjugated systems

“…Since the classical polycyclic aromatic hydrocarbons (PAHs), such as anthracene, [ 22 ] pyrene, [ 23 ] tetracene (TC), [ 24 ] perylene, [ 25 ] naphthalene diimides, [ 26 ] perylene diimides, [ 27 ] benzothiadiazole, [ 28 ] and fluorinated aromatics, [ 29 ] have been widely employed as photoluminescent materials or n/p‐type carrier‐transfer compounds in diverse devices, it is our research interest in developing novel PAHs with diverse molecular structures as well as their micro/nanoaggregates, and further understanding their structure–property relationships. Besides, the replacement of sp [ 2 ] carbons of PAHs with heteroatoms (i.e., N, O, P) would create a new type of materials (namely, heteroacenes or heteroarenes) as important active elements in diverse organic electronics.…”
