A bifunctional MOF for selective CO 2 capture and efficient aqueous‐phase sensing of 2,4,6‐trinitrophenol (TNP) has been rationally designed and synthesized. Owing to the presence of basic (−NH 2 ) functionalized pore surface, the MOF exhibits selective adsorption of CO 2 with a high value of heat of adsorption ( Q st = 46.5 kJ mol −1 ) which is about 10 kJ mol −1 higher than that of the analogues MOF without −NH 2 functionality. Further, the MOF shows highly selective, aqueous‐phase sensing of TNP over other competing NACs. The observed selectivity of MOF for CO 2 capture and sensing of TNP has been correlated to the stronger interaction of the guest molecules with the basic −NH 2 groups in the 1D channels, unveiled from the DFT calculations.
