Claims3
A compound represented by the formula:
- Y1a represents Si(R4b)2, wherein each R4b in (R4b)2 independently represents optionally substituted C1-C4 alkyl;
- or C(R4c)2, wherein each R4c in (R4c)2 represents hydrogen or optionally substituted C1-C4 alkyl;
- Y1b represents O, S, NR5a, wherein R5a represents optionally substituted C1-C4 alkyl;
- Si(R5b)2, wherein each R5b in (R5b)2 independently represents optionally substituted C1-C4 alkyl;
- or C(R5c)2, wherein each R5c in (R5c)2 represents hydrogen or optionally substituted C1-C4 alkyl;
- each of Y2a Y2b, Y2c, and Y2d independently represents N, NR6a, or CR6b, wherein each of R6a and R6b is independently present or absent, valency permitting, and, when present, independently represents hydrogen, optionally substituted C1-C4 alkyl, halogen, hydroxyl, amino, nitro, or thiol;
- and
- each of Y3a, Y3b, Y3c, Y3d, Y3e, Y4a, Y4b, Y4c, and Y4d independently represents N, O, S, NR6a, CR6b, wherein each of R6a and R6b is independently present or absent, valency permitting, and, when present, independently represents hydrogen or optionally substituted C1-C4 alkyl;
- or Z(R6c)2, wherein Z is C or Si, and wherein each R6c in (R6c)2 independently represents hydrogen or optionally substituted C1-C4 alkyl.
