A porous covalent triazine framework (CTF) consisting of both an electron-deficient central triazine core and electron-rich aromatic building blocks is reported. Taking advantage of the dual nature of the pore surface, bimodal functionality has been achieved. The electron deficiency in the central core has been utilized to address one of the pertinent problems in chemical industries, namely separation of benzene from its cyclic saturated congener, that is, cyclohexane. Also, by virtue of the electron-rich aromatic rings with Lewis basic sites, aqueous-phase chemical sensing of a nitroaromatic compound of highly explosive nature (2,4,6-trinitrophenol; TNP) has been achieved. The present compound supersedes the performance of previously reported COFs in both the aspects. Notably, this reports the first example of pore-surface engineering leading to bimodal functionality in CTFs.

A new flexible tritopic ligand, 1,3,5-tri(4-cyanophenoxy)benzene (1), was synthesised by the reaction of phloroglucinol and para-fluorobenzonitrile. Compound 1 crystallises in the non-centrosymmetric space group Pna21. The reaction of ligand 1 with AgBF4 in the presence of different aromatic guest molecules was found to result in coordination polymers, namely, {[Ag3(1)2(BF4)3(H2O)2]·2C7H8·2CH2Cl2}n (2), {[Ag3(1)2(BF4)3(H2O)2]·2C6H6·2CH2Cl2}n (3). The crystal structures of 2 and 3 reveal that ligand 1 is linked by AgI ions into three-dimensional networks containing channels that are occupied by dichloromethane and aromatic guest molecules. The luminescent properties of crystalline 1 and 3 differ significantly.
