1. A optoelectronic device comprising:
a) a first hole-collecting electrode; b) an optional hole-transporting layer; c) a layer comprising a mixture of an electron donor material and an electron acceptor material; and d) a second electron-collecting electrode, wherein the electron donor material comprises a compound of Formula (I): wherein X is oxygen or sulfur; A1 and A2 are independently selected from substituted and unsubstituted aryl or heteroaryl groups, wherein each individual A1 within the (A1)m moiety can be independently selected from a substituted or unsubstituted aryl or heteroaryl group, and each individual A2 within the (A2)n moiety can be independently selected from a substituted or unsubstituted aryl or heteroaryl group; B1 is independently selected from substituted and unsubstituted aryl or heteroaryl groups; m is independently selected from 1, 2, 3, 4, 5, 6, 7, 8, or 9; n is independently selected from 1, 2, 3, 4, 5, 6, 7, 8, or 9; p is independently selected from 0 or 1; E1 and E2 are independently selected from a nonentity, H, or a substituted or unsubstituted aryl or heteroaryl group or a C1-C12 alkyl group; and R1, R2, R3, and R4 are independently selected from H, C1-C12 alkyl, and —C(═O)—O—C1-C12 alkyl. |
