## Abstract Bisfuran‐s‐tetrazine (FTz) and its copolymers with cyclopenta[2,1‐b:3,4‐b′]dithiophene (CPDT) and benzo[1,2‐b:4,5‐b′]dithiophene (BDT) (PCPDTFTz and PBDTFTz) are prepared with the alternating s‐tetrazine and CPDT or BDT units bridged by a furan ring. Their optical and electrochemical pr
2,5-Bis(trifluoromethyl)phenyl]acetylene [BTFPA; HCzCC6H3-2,5-(CF3)2] polymerized with W, Mo, and Nb catalysts to produce methanolinsoluble polymers in high yields. The poly(BTFPA) produced by the W(CO)6-based catalyst at 30 ~ was soluble in I-(CF3)2C6H4, and had relatively high molecular weight ([q
## SYNOPSIS Two new conjugated poly-Schiff bases (PPpP and PPmP) were synthesized by polycondensation of p-phenylene diamine or m-phenylene diamine with 2,6-pyridine dicarboxaldehyde. PPpP and PPmP can form charge transfer complexes with iodine. Maximum conductivity of PPpP-iodine complex at room
