Two water‐stable indium metal‐organic frameworks, (NH2Me2)3[In3(BTB)4]·12DMA·4.5H2O (In‐MOF‐1) and (NH2Me2)9[In9O6(BTB)8(H2O)4(DMSO)4]·27DMSO·21H2O (In‐MOF‐2) (BTB = 4,4¢,4¢¢‐benzene‐1,3,5‐tribenzoate) with 3D interpenetrate structure has been constructed by regulating solvents. Structure analysis revealed that In‐MOF‐1 has a three‐dimensional (3D) structure with a single metal core, while In‐MOF‐2 features an octahedron cage constructed by three kinds of metal clusters to further form a 3D structure. The fluorescence investigations show that In‐MOF‐1 and In‐MOF‐2 are potential MOF‐based fluorescent sensors to detect acetone and Fe3+ ions in EtOH or water with high sensitivity, excellent selectivity, recyclability and a low detection limit. Moreover, the fluorescence mechanisms of In‐MOF‐1 and In‐MOF‐2 toward acetone and Fe3+ ions were further explained. In addition, In‐MOF‐2 has higher thermal and framework stability than In‐MOF‐1. The activated In‐MOF‐2 presents a high BET surface area of 998.82 m2g‐1 and a pore size distribution of 8 to 16 Å. At the same time, In‐MOF‐2 exhibits high selective CO2 adsorption for CO2/CH4 and CO2/N2, respectively. Furthermore, the adsorption sites and adsorption isotherms were predicted using Grand Canonical Monte Carlo (GCMC) simulations, and the adsorption energy of the lowest‐energy adsorption configuration was calculated using molecular dynamics (MD) simulations.

The modulation of coordination polymers (CPs) with specific structures and functions is greatly challenging. This work explores the function of the substituent in the modulation of structures, luminescence, and sensing abilities for CPs. Compared with 4,4′-((9H-fluoren-9-ylidene)-methylene)dipyridine (L-2), a new aggregate-induced emission (AIE) molecule 4,4′-((2,7-di-tertbutyl-9H-fluoren-9-ylidene)-methylene)dipyridine (L-1) with two tert-butyl substituents was successfully synthesized. L-1 and L-2 were developed as functional ligands to construct two distinct one-dimensional (1-D) double-chain CPs [Cd(L-1)(2,5-TDC)(H 2 O)] n (1) and [Cd(L-2)(2,5-TDC)(H 2 O)] n (2) through very similar synthetic routes. 1 is fabricated by L-1 linking with two 2,5-TDC-Cd single chains to form a double-chain architecture. Meanwhile, 2 has a 2,5-TDC-Cd double-chain skeleton with L-2 terminal ligands. 1 and 2 have good water and thermal stabilities but show different luminescent properties. Compared with 1, 2 has an obviously enhanced TNP sensing ability. The quenching constant (4.5 × 10 4 M −1) of 2 toward TNP is nearly three times higher than that (1.55 × 10 4 M −1 ) of 1. The TNP detection limit (5.27 × 10 −4 mM) of 2 is about 1 order of magnitude lower than that (4.67 × 10 −3 mM) of 1. The mechanism of distinct sensing performance for 1 and 2 toward the TNP is explored in detail.
