Claims20
A resin comprising a unit of the following-Chemical Formula 1:
- wherein, in Chemical Formula 1,
- X1 to X4 are the same as or different from each other, and are each independently O or S,
- R1 to R4 are the same as or different from each other, and are each independently a substituted or unsubstituted aryl group;
- or a substituted or unsubstituted heteroaryl group,
- R5 and R6 are the same as or different from each other, and are each independently a substituted or unsubstituted alkylene group;
- or a substituted or unsubstituted cycloalkylene group,
- R101 and R102 are the same as or different from each other, and are each independently a substituted or unsubstituted alkyl group;
- a substituted or unsubstituted cycloalkyl group;
- a substituted or unsubstituted aryl group;
- or a substituted or unsubstituted heteroaryl group,
- r101 is 0, 1 or 2, and when r101 is 2, two R101's are the same as or different from each other,
- r102 is 0, 1 or 2, and when r102 is 2, two R102's are the same as or different from each other,
- La is a direct bond;
- or —C(═O)-L′-,
- L′ is a substituted or unsubstituted arylene group,
- m and n are each independently 0 or 1, and
- * means a moiety linked to the main chain of the resin.
