Descrizione

Applicazioni

1,4,5,8-Naphthalenetetracarboxylic dianhydride, also known as NTCDA or NTCDA-DA, is commonly used as a building block or precursor for the synthesis of organic semiconducting materials. These materials can be employed in various organic electronic devices, including organic field-effect transistors (OFETs), organic photovoltaic (OPV) devices and organic photodetectors. NTCDA can be utilized as an electron-accepting material or an anchoring unit in studies on dye-sensitized solar cells (DSSCs) for enhancing the photovoltaic performance of the device.

1,4,5,8-Naphthalenetetracarboxylic dianhydride, also known as NTDA or NTCDA, is an organic compound related to naphthalene. NTDA is most commonly used as a precursor to naphthalenediimides (NDIs) (such as napthalenetetracarboxylic diimide), which has many uses, especially in energy harvesting and storage. NTCDA is used in electrode interface for organic photovoltaics, selective adsorption and to fabricate copolyimides to use in membranes for gas separation and for enhanced proton exchange membranes in fuel cells.
