However, the precise construction of highly crystalline and functionalized 3D COFs remains a major challenge, due to the limited availability of suitable 3D building blocks and the inherent complexity of synthesis. Herein, by selecting a unique 3D precursor containing a bicarbazole motif, we successfully synthesized two 3D COFs (3D\u2010BCZ\u2010COF\u20101 and 3D\u2010BCZ\u2010COF\u20102) featuring threefold interpenetrated\n                    <jats:bold>qtz<\/jats:bold>\n                    topology.
