PROBLEM TO BE SOLVED: To provide a nonlinear optical compound which has both nonlinearity and heat resistivity in a sufficiently high level. SOLUTION: The nonlinear optical compound is expressed in a general formula (1). Here, in the general formula (1), n is an integer between 2 and 4, R<SP>1</SP>shows a 1-4C alkyl group, n pieces of R<SP>1</SP>may be the same, or different from each other. p and q are integers between 0 and 2 independently, and p+q is two or less. Ar<SP>1</SP>and Ar<SP>2</SP>show a predetermined aryl group or a predetermined hetero-aryl group independently, and when p+q is two, Ar<SP>1</SP>and Ar<SP>2</SP>may be the same, or different from each other. D and A show a predetermined electron donor group and a predetermined electronic acceptance group respectively. COPYRIGHT: (C)2010,JPO&INPIT |
