• L2 is a heteroatom bridge in conjugation with the ring system containing R2a, R2b, R2c, R2d, Q1, Q2, Q3, Q4, Q5;
• wherein R2a, R2b, R2c, R2d, Q1, Q2, Q3, Q4, Q5 are each independently selected from —H and any electron withdrawing or electron donating group,
• wherein Ak is alkyl,
• X is any halogen,
• wherein o is 0-10, p is 0-1 when o is less than or equal to one and 1 when o is greater than 1,
• wherein R1 is an insulating resistive tail;
• wherein Z is substituted or unsubstituted hydrocarbon cyclic or chain linkage,
• Y is any hydrocarbon chain which may be interrupted by a hetero atom at the point of attachment.
