1. A diamine compound represented by formula (1) below,where A denotes:
a divalent aliphatic group R1, which may have a substituent and has a carbon number from 1 to 10; a divalent aromatic group Ar1, which has from 1 to 4 ring structures and may have a substituent; a group composed of divalent aromatic groups Ar2 and Ar3, each of which has from 1 to 4 ring structures and may have a substituent, the group being represented by a formula [—Ar2—Ar3-] (where Ar2 and Ar3 may be same as or different from each other); a group composed of divalent aromatic groups Ar4 and Ar5, each of which has from 1 to 4 ring structures and may have a substituent, and Z, which is an ether group (—O—), a thioether group (—S—), or a sulfone group (—SO2—), the group being represented by a formula [—Ar4—Z—Ar5-] (where Ar4 and Ar5 may be same as or different from each other); a group composed of a divalent aromatic group Ar6, which has from 1 to 4 ring structures and may have a substituent, and a divalent aliphatic group R2, which may have a substituent and has a carbon number of from 1 to 10, the group being represented by a formula [—Ar6—R2—]; or a group composed of divalent aromatic groups Ar7 and Ar8, each of which has from 1 to 4 ring structures and may have a substituent, and a divalent aliphatic group R3, which may have a substituent and has a carbon number from 1 to 10, the group being represented by a formula [—Ar7—R3—Ar8-] (where Ar7 and Ar8 may be same as or different from each other), wherein the substituent is at least one group selected from a methyl group, an ethyl group, a propyl group, a butyl group, a trifluoromethyl group, a phenyl group, a phenoxy group, a phenylthio group, and a benzenesulfonyl group. |
