Good solubility is the premise in solution processing of conjugated polymers while strong π-π interaction in the main chain is generally the main cause for bad dissolution. In this paper, our strategy is intruducing the auxiliary solvent and repeat unit with the similar structure as solvent in the main chain for good solubility of conjugated polymer. Based on the well dissolution between the auxiliary solvent and polymer repeat units induce a quasi-single polymer chain and advanced self-assembly, conjugated polymer coils and reversible supramolecular gels were acheived. R-limonene was added into chlorobenzene as the auxiliary solvent for the well solubility of poly(2-(4-(3',7'-dimethyloctylo-xyphenyl)-1,4-pheny-lene-vinylene (P-PPV). Atomic force microscopy (AFM) images of the spin-coated films with solutions of low concentration showed the isolated P-PPV polymer coils and the fine structure inside the coils in chlorobenzene/R-limonene mixture; while with the absence of R-limonene, the packing of sub-polymer chain was clearly observed. In concentrated solution, P-PPV formed a reversible supramolecular gel at the concentration of 2 mg mL⁻¹ with good temperature response characteristics in chlorobenzene/R-limonene mixture, and the gel temperature of P-PPV is in the range of 55 °C to −35 °C. Aggregations with different curvatures were obtained in different solvents, which made us further understand the pliability of conjugated polymer. P-PPV molecular chains were dissolved by the enhanced solubility of alkyl sidechain and phenylene ethylene, that made it became pliable and then entangled, which allowed the assembly of polymer coils with high curvature and supramolecular gel with high ratio of solvent wrap. The fluorescence quantum yield and fluorescence lifetime were both improved in conjugated polymer coils and reversible supramolecular gels, but the physical cross-linking points by π-π interaction showed low energy level as those of charge trap sites, where the mobility became lower. In the organic light emitting diodes (OLED), the uniform physical cross-linking network made the structure of P-PPV more stable and could effectively improve the stability, brightness, and lifetime of the device.
