The conjugation of metal–organic frameworks (MOFs) with covalent organic frameworks (COF), as a catalytically active nanocomposite with integrated properties, is a smart strategy for developing efficient catalytic systems. Herein, we report the design and synthesis of NH 2 - Glu-MOF/MT- COF nanocomposite using the integration of glutamate MOF (NH 2 - Glu-MOF) and melamine-terephthaldehyde COF (MT- COF) via imine bond connection. The synthesized NH 2 - Glu-MOF/MT- COF nanocomposite has been fully characterized using FT-IR, XRD, BET, TEM, FE-SEM, EDX, EDX mapping, TGA, and ICP- OES techniques. Analyses demonstrate that NH 2 - Glu-MOF/MT- COF nanocomposite has ideal structural and compositional properties such as good specific surface area (241.631 m 2 g−1), high pore volume, and high thermal stability (530°C). Because of such unbeatable structural and compositional features, NH 2 - Glu-MOF/MT- COF nanocomposite shows much better catalytic activity for the synthesis of a wide library chromeno[4,3-b]quinoline- 6-one derivatives than parent materials (NH 2 - Glu-MOF or MT- COF). Additionally, NH 2 - Glu-MOF/MT- COF nanocomposite demonstrated supreme recyclability during five catalytic cycles.
