Synthesis of tetraalkyl naphthalene bisanhydride and its model condensations with amines

To improve the solubility of naphthalene bisanhydride (NTCA), four alkyl groups are incorporated to the naphthalene core via a five-step procedure. The new naphthalene bisanhydride derivative (TO-NTCA) shows much higher reactivity than the parent NTCA in the model condensations with ortho-diaminobenzene and 2-ethylhexylamine and gives corresponding soluble molecules with excellent yields. Hence, TO-NTCA is a potential monomer for condensations.

Photoconductive members

A compound comprising a bisbenzamidazoleperinone of the following formula wherein each of R1, R2, R3, and R4 are the same or different and are independently selected from the group consisting of hydrogen, alkyl, aryl, hydrocarbon, which may be optionally substituted or arranged in such a way as to form a cyclic ring which can be either saturated or unsaturated and halogen.
