Stille type P–C coupling polycondensation towards phosphorus-crosslinked polythiophenes with P-regulated photocatalytic hydrogen evolution

“…into polymeric backbones has become a powerful strategy for ne-tuning photophysics, redox characteristics, molecular organizations, and optoelectronic functionalities of the OCPs. [12][13][14][15][16][17][18] For example, embedding boron (B)-building blocks into OCPs induced a strong p-p* electronic coupling between B and polymeric backbones, which endowed the polymers with excellent toxic chemical (uoride, cyanide, and amines) sensing properties, electron-transporting properties, and electron-accepting properties. 12,[19][20][21][22] The introduction of sulfone (SO 2 )-containing units enhanced the electron-accepting character and water affinity of OCPs, which afforded new polymeric systems with excellent photocatalytic H 2 evolution performance.…”

Synthesis and Characterizations of Polythiophene Networks with Nonplanar BN Lewis Pair Building Blocks

“…Organic π-conjugated polymers (OCPs) have drawn significant attention in the areas of photocatalysis, bioimaging/sensing, and organic electronics. − Functionalities of OCPs are highly dictated by the chemical and electronic structures of building blocks. − Recently, the introduction of main-group elements (such as B, − S, , Si, P, − etc.) containing building blocks has become an effective strategy to fine-tune the photophysical properties, redox properties, molecular organizations, and optoelectronic properties of OCPs.…”
