Naphthalene Carboxylic Anhydride for the Synthesis of Functional Materials
No.193(August 2023)
TCI offers naphthalene tetracarboxylic anhydrides and its derivatives with various substitution patterns and 1,2,5,6-naphthalene tetracarboxylic dianhydride (1,2,5,6-NTCDA, 1) has newly been commercialized. Unlike other NTCDA derivatives, 1 has a folded structure and is expected to improve solubility. Polyimides, electrochromic material,1) and n-type organic semiconductors2) have been reported using 1. In addition, it has been reported that 1 can be regioselectively brominated and utilized in the cross-coupling to synthesize donor-acceptor polymers.3)
