PROBLEM TO BE SOLVED: To provide a new material having sufficiently high solubility, causing no problems including crystallization and film cracking, capable of thin film formation, and having the ability to transport electrons. SOLUTION: A naphthalenetetracarboxylic acid diimide compound improved in solubility and introduced with bulky substituent(s) and represented by formula (1) [wherein, X<SP>11</SP>is a (substituted) 1-15C bivalent alkylene group optionally interposed with an ether linkage (an oxygen atom may be interposed at the position binding to R<SP>11</SP>or the N atom), (substituted) bivalent arylene group or (substituted) bivalent aralylene group; R<SP>11</SP>is represented by formula (2), (3) or (4); R<SP>12</SP>is a (substituted) 1-15C alkyl, (substituted) aryl or (substituted) aralkyl group], and a polymer obtained by polymerizing said compound, are provided respectively.
