Specifications | MSDS | Literature and Reviews

NTCDA (CAS number 81-30-1) has a naphthalene core with four carboxylic acids at 1,4,5,8-positions, each adjacent carboxylic acids forms an anhydride.

NTCDA (1,4,5,8-naphtalenetetracarboxylic dianhydride) is aromatic, stable, planar and highly symmetric with unusual electrical properties. Due to the electron deficient nature of the carboxylic groups, NTCDA is well known as a strong electron-accepting molecule with a high electron affinity of 4.0 eV. Studies shows that NTCDA dramatically improve electric conductivity in a co-deposited film of NTCDA and several metals, including indium, magnesium and aluminium. The high electron conductivity of co-deposited NTCDA/In film strongly suggests that a co-deposited NTCDA/In film is an excellent electron transporting layer for OLED and photovoltaic devices.

Electron traps can be created by the introduction of trace amounts of n-type small molecule semiconductor NTCDA into polyethylenimine (PEI), which effectively reduces the leakage current and improves the breakdown strength and energy storage properties of the composite at high temperature. Especially, excellent energy storage performance is achieved in 0.5 vol.% NTCDA/PEI at the high temperatures of 150 and 200 °C.
