Abstract:
1. A compound of the general formula IIIa: where each W is independently selected from C(CN) R where the D groups are selected from: where where Y W where each X is selected independently from 0, NR′, S, Se, where R′ is selected from C1-C30 alkyl, C1-C10 aryl and C1-C8 heteroaryl, each Y is independently selected from N and CR9 where R9=H, halogen, C1-C30 alkyl, C1-C30 alkenyl, C1-C30 alkynyl, each linear or branched, substituted or unsubstituted, OR′, SR′, SiR′ each Z is independently selected from N and CR10 where R10=H, halogen, C1-C30 alkyl, C1-C30 alkenyl, C1-C30 alkynyl, each linear or branched, substituted or unsubstituted, OR′, SR′, SiR′ or wherein R9 and R10 form a 5-membered or 6-membered ring, where the E groups are selected from: where V N and C—R where R=H, halogen, C1-C30 alkyl, C1-C30 alkenyl, C1-C30 alkynyl, each linear or branched, substituted or unsubstituted, C3-C10 aryl or C1-C8 heteroaryl, substituted or unsubstituted, OR′, SR′, SiR′ Y O, S, Se, P(R), P(O)R, Si(RR′), C(RR′) and N(R), where R and R′ are each independently selected from H, linear or branched, substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, COR′, COOR′ and OR′, where R′ is selected from C1-C30 alkyl, C3-C10 aryl and C1-C8 heteroaryl, and X O, S, Se, P(R), P(O)R and Si(RR′), and R and R′ are each independently selected from H, C1 to C20 alkyl, linear or branched, substituted or unsubstituted, C3 to C6 aryl or C3 to C8 heteroaryl, OR′, SR′, SiR′ and where R3, R4 and R5 are each independently H, C1 to C20 alkyl, linear or branched, substituted or unsubstituted, C3 to C6 aryl or C3 to C8 heteroaryl, OR′, SR′, SiR′ bd is independently *—C═C—* or *—C≡C—*, n, m, o, p, q, r, s and t may each independently be 0 or 1, with the proviso that at least one parameter is 1, where one donor unit formed from the groups bd, E and D has at least 10 conjugated electrons and the bonds identified with the asterisk* indicate the bonds to further groups in the compounds.
