1. A composition for forming an electroactive coating, comprising:
at least one compound of formula (1) as a monomer, wherein
X is selected from the group consisting of S, O, Se, Te, PR2 and NR2, wherein R2 is selected from the group consisting of hydrogen, and substituted and unsubstituted alkyl, aryl, heteroaryl, alkanoyl, and aryloyl groups;Y is hydrogen (H), or a precursor of a good leaving group Y− whose conjugate acid (HY) has a pKa of less than 30;Z is hydrogen (H), silyl, or a precursor of a good leaving group Z− whose conjugate acid (HZ) has a pKa of less than 30;b is 0, 1 or 2;each R1 is a substituent, wherein when b=2, the two R1 are the same or different and may joint together to form a ring; andthe at least one compound of formula (1) comprises at least one compound of formula (1) with Z═H and Y≠H; an acid as a polymerization catalyst selected from the group consisting of a protic acid, a polymeric acid, and a non-transitional Lewis acid; and at least one functional component, selected from the group consisting of a solvent, a polymerization retardant, a polymer binder, a dopant, a dielectric layer protection agent, a plasticizer, an impact modifier, and a crosslinking agent, wherein the at least one functional component contains at least a polymerization retardant comprising at least one Lewis base having a stronger basicity than the monomer, and when the polymerization retardant comprises a carbonate, the carbonate is selected from dimethyl carbonate, ethylene carbonate, and propylene carbonate.
