Rational Design of Benzoimidazoisoindolone-Linked Conjugated Ladder Polymer for Enhanced Visible-Light-Driven Photocatalytic Water Oxidation

Key Points

• The study aims to understand how the structure of conjugated polymers affects their efficiency in solar water oxidation.
• Synthesis of two π-conjugated analogues with different linker structures.
• Comparison of photocatalytic efficiency between a flexible and a rigid linker.
• The rigid ladder linker shows significantly higher photocatalytic efficiency than the flexible single-strand linker.
• Backbone topology is a crucial factor affecting photocatalytic performance.
