- graphitic carbon nitride (g-CN), a type of 2D semiconducting polymers, has gained significant attention in recent years for optoelectronic and catalytic applications. However, g-CN has been studied on a powder material, which suffers from limited dispersibility, difficult recovery, and low surface accessibility. In this study, we report that controlled g-CN, which has high-aspect ratio and expanded interlayer spacing, can exhibit its true LC phase in concentrated sulfuric acid. By utilizing its LC phase, more importantly, we could fabricate a g-CN fiber for the first time.; The fluids of fascinating nanomaterials have recently been reported to exhibit liquid crystalline (LC) phases, and these mesophases have attracted significant interest in both fluid physics and cutting-edge applications
