Abstract:
A binaphthyl compound represented by General Formula (G1) is provided. In General Formula (G1), Ar2 represents any of an arylene group, a cycloalkylene group, and a cycloalkenylene group, and m is any of 0 to 3; R3 represents any of hydrogen, an alkyl group, and an alkoxy group; and one of R and R1 represents a substituent represented by General Formula (G2) and the other thereof represents hydrogen. In General Formula (G2), Ar1 represents any of an arylene group, a cycloalkylene group, and a cycloalkenylene group, and k is any of 1 to 3; and R2 represents any of hydrogen, an alkyl group, and an alkoxy group.
