Application
Naphthalene-1,4,5,8-tetracarboxylic Dianhydride, purified by sublimation, serves a crucial role in the development of advanced electronic devices due to its unique structural and chemical properties. This light brown solid is composed of a naphthalene core with four carboxylic acids positioned at the 1, 4, 5, and 8 locations, where each pair of adjacent carboxylic acids forms an anhydride. Its aromatic, stable, and planar structure, along with its high symmetry, contributes to its favorable electrical characteristics. Recognized as a potent electron acceptor with an electron affinity reaching 4.0 eV, it enhances the electrical conductivity of thin films when combined with various metals like indium, magnesium, and aluminum. These co-deposited films, especially NTCDA/In, have demonstrated high electron conductivity, making them ideal as electron transport layers in organic light-emitting diodes and photovoltaic devices. Consequently, Naphthalene-1,4,5,8-tetracarboxylic Dianhydride is instrumental in fabricating fuel cells, thin-film transistors (OTFTs), lithium-ion batteries, and organic photovoltaics.
