An electronic or optoelectronic device comprising a small molecule compound of Formula B:

• wherein M is selected from sulfur (S), oxygen (O), selenium (Se), tellurium (Te), —N(R1)—, —C(R2)2—C(R3)2—, —CR2═CR3
• wherein H2 is
• wherein J1 is a nonentity;
• wherein Q is a bivalent, trivalent, or tetravalent aryl or heteroaryl group;
• wherein p is 1, 2, or 3;
• wherein each X1, X2, Y1, and Y2 is halogen;
• wherein each H1 and L1 are independently selected from -A1-B2,
• wherein each B2 is independently selected from H and
• wherein n is an integer between 0 and 5, inclusive, and m is an integer between 0 and 5, inclusive, and 1<m+n≤5 for each structure where m and n occur together;
• wherein A1 is independently selected from substituted or unsubstituted aryl group, substituted or unsubstituted heteroaryl group except thiophene,
• where A2 is independently a substituted or unsubstituted aryl group or substituted or unsubstituted heteroaryl group;
• wherein B1 is a substituted or unsubstituted thiophene;
• and
• wherein R1, R2, R3, R4, and R5 are each independently H or a substituent.
