Patent ID: 8569513

Claim:
A compound having a triptycene moiety represented by formula (1): wherein A 1 and A 2 each respectively represents —S—, —O—, or —CO; R 1 and R 3 each respectively represents a substituent selected from the monovalent group consisting of a substituted or non-substituted C 1-15 linear aliphatic hydrocarbon group, substituted or non-substituted C 3-15 branched aliphatic hydrocarbon group, substituted or non-substituted C 3-15 cyclic aliphatic hydrocarbon group, substituted or non-substituted C 6-15 aryl group, amino group, or a substituent forming by bonding the substituent selected from the monovalent group and one selected from the divalent group consisting of a substituted or non-substituted alkylene group, substituted or non-substituted arylene group, substituted or non-substituted ester group, carbonate ester group, ether group and any combinations of two or more selected from them; n is an integer from 0 to 2; R 4 and R 5 each respectively represents an electron-withdrawing group having a Hammett's substituent constant σ p of equal to or more than 0, provided that R 4 and R 5 do not bond to each other to form a ring; L 11 , L 12 , L 21 and L 22 each respectively represents a single bond or a divalent group selected from the group consisting of —O—, —S—, —S(═O) 2 —, —CO—, —COO—, —COO—, —OCOO— and —NR A — where R A represents a C 1-7 alkyl group or hydrogen atom, —CH 2 — and any combinations thereof; Z 1 and Z 2 each respectively represents a divalent 5- or 6-membered cyclic linking group; R 21 and R 22 each respectively represents a hydrogen atom or substituted or non-substituted alkyl group; and m1 and m2 each respectively represents an integer of from 0 to 2.
