“…Tis limitation is mainly attributed to the design contradiction between bio-based sources and polymer performance. Since polyimides are generally prepared by condensation of dianhydrides and diamines, the application performance of polyimides can be changed by designing the structure of bioderived monomers [32,33]. For example, Sawada et al used isosorbide [34] to synthesize a series of polyimides with excellent optical transparency, a low refractive index, a low dielectric constant, and small birefringence.…”

With the rapid development of information, energy, and materials industries in China, the demand for high-performance polymers is gradually increasing. Photosensitive polyimide (PSPI) has emerged as an ideal choice for high-performance optoelectronic materials due to its outstanding thermal stability, mechanical strength, and low dielectric constant. In particular, bio-based photosensitive polyimide prepared from bio-based chemicals, as a green polymer material, not only reflects the advantages of environmental protection and resource efficiency but also contributes to carbon neutrality. However, how to improve the photolithography efficiency while maintaining the thermodynamic performance and environmental friendliness and how to balance the pros and cons of low-molecular-weight matrixes are still challenges in the research. This review systematically summarizes the synthesis and performance characteristics of photosensitive polyimides, bio-based polyimide, and bio-based photosensitive polyimides and further explores the future application prospects of bio-based polyimides in the field of high-performance optoelectronic materials.
