Abstract

Summary: Two new polymers containing 2‐pyrazoline units in the main chain were synthesized for the first time by a Suzuki polycondensation between a 2‐pyrazoline monomer and aryl diboronic esters. The polymers showed high photoluminescence (PL) in both the solution and the solid state; quantum yields of PL in toluene were higher than 76%. Thermogravimetric analysis and cyclic voltammetry showed that the polymers had high thermal stability and good reversibility under electrochemical oxidation.

New polymers (2 and 3) with strong photoluminescence and good reversibility under electrochemical oxidation were synthesized here.

## Abstract **Summary:** Three new soluble __π__‐conjugated polymers containing 1,3,5‐triazine units in the main chain, Pa–Pc, were synthesized. The polymers showed optical properties in solution that were mainly dependant on the properties of the substituting R groups, on the triazine ring. Hence,

## Abstract Two new polyimides (ODA‐PI and HDA‐PI) having 1,4‐phenylenediethynylene unit and octyloxy groups were synthesized. Judging from inherent viscosities of their precursor PAAs (1.42 and 1.62 dL · g^−1^), the two PIs were very high in molecular weight. Casting and thermal imidization of PAA
