The invention is directed to a process for preparing a bis(hydroxymethyl)perylenetetracarboximide compound by reacting perylene-3,4,9,10-tetracarboximide with formaldehyde. The bis(hydroxymethyl)perylenetetracarboximide can be isolated or further reacted in a one pot synthesis to yield a compound of the formula ##STR1## wherein X.sub.1 and X.sub.2 are organic radicals.

Provided are mono- and diimide naphthalene compounds for use in the fabrication of various device structures. In some embodiments, the naphthalene core of these compounds are mono-, di-, or tetra-substituted with cyano group(s) or other electron-withdrawing substituents or moieties. Such mono- and diimide naphthalene compounds also can be optionally N-substituted.
