Photocatalysis offers a promising way to convert the vast supply of sunlight into useful chemical energy. Among the materials attracting growing attention are polyheptazine imides, which have structural and functional features that make them particularly effective for photocatalytic reactions. Until recently, scientists had only limited insight into how changes in their structure influence their electronic and optical behavior across the many possible materials in this family.

Researchers led by a team at the Center for Advanced Systems Understanding (CASUS) at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have now introduced a dependable and reproducible theoretical approach to tackle this problem. Their predictions were validated through measurements on real material samples. The team believes this advance could significantly accelerate research on polyheptazine imides and spark rapid growth in the field.
