Beschreibung
1,4,5,8-Naphthalenetetracarboxylic dianhydride (NTCDA) has a naphthalene core with four carboxylic acids at the 1, 4, 5, and 8 positions, with each adjacent carboxylic acid forming an anhydride. NTCDA is aromatic, stable, planar, and highly symmetric chemically, and also possesses favourable electrical properties. Due to the electron-deficient nature of the carboxyl group, NTCDA is known to be a strong electron acceptor molecule with an electron affinity as high as 4.0 eV. It has been demonstrated that NTCDA significantly improves the electrical conductivity of co-deposited thin films of NTCDA and a wide range of metals including indium, magnesium and aluminium. The high electron conductivity of co-deposited NTCDA/In films also strongly suggests that co-deposited NTCDA/In films are excellent electron transport layers for organic light emitting diodes and photovoltaic devices.
Chemische Eigenschaften
Light brown solid
Verwenden
NTCDA can be used in the fabrication of a variety of devices such as fuel cells, thin film transistors (OTFTs), lithium ion batteries, and organic photovoltaics (OPV).
Verwenden
1,4,5,8-Naphthalenetetracarboxylic Dianhydride is used as a reagent in the preparation of novel fluorescent markers for hypoxic cells of naphthalimides with two heterocyclic side chains for bioreductive binding.
Allgemeine Beschreibung
1,4,5,8-Naphthalenetetracarboxylic dianhydride (NTCDA) is a tetrafunctional monomer that can be used as an electron transporting material in organic electronics.
