1 Source of materials

The title complex was synthesized from a mixture of quinolin-8-amine, naphthalene-2-sulfonyl chloride and potassium trifluoro(phenyl)--borane suspended in MeCN under air atmosphere at 130 °C for 24 h. Until the completion of this reaction, the resulting residue was adsorbed onto silica gel by rotary evaporation of a DCM solution, loaded directly onto a silica gel column, and purified by rotary evaporation by eluting first with EtOAc:PE 1:5 to get the target product as yellow solid. Crystals of this target product formed in a mixed system of n-hexane and dichloromethane (DCM as the good solvent and n-hexane as the poor solvent).

2 Experimental details

All the H atoms were placed geometrically.

At present, one of the research hotspots in the field of organic fluorescent materials is the synthesis of tetracoordinated organoboron complexes, especially the construction strategy of N,N-chelated B,B-diaryltetracoordinated boron compounds, due to the harsh synthetic conditions of these compounds, organic metal reagents that are highly sensitive to both water and air are required in the experimental process. A one-pot three-component synthetic strategy of N,N-chelated-B,B-diaryl tetra-coordinated boron complexes is reported. 8-aminoquinoline is used as the precursor of N,N-chelated ligands, and potassium phenyltrifluoroborates (PhBF3K), which are chemically stable and available in the market, is used as the source of diphenyl groups on the boron centers.

Single-crystal X-ray diffraction (SC-XRD) analysis revealed that the asymmetric unit of the title compound is comprised of one title molecule. As shown in figure, the central boron atom B1 adopts a typical tetrahedral coordination geometry to connect with two nitrogen atoms (N1, N2) from the quinoline unit and two carbon atoms (C8, C22) from two different benzene rings. The bond lengths and bond angles surrounded the central B atoms are in the range of 1.607(3)–1.623(3) Å and 94.83(14)°–117.99(16)°, respectively, which are comparable to some previously reported boron-containing compounds [5], [6], [7], [8]. Due to the tetrahedral geometry of central B atom, the dihedral angles among the two benzene rings connected to the B atom and the quinoline unit are 67.91°, 73.27° and 84.14°, respectively. On the other hand, because of the unique configuration of the sulfanilamide group, both of the quinoline unit and one of the benzene rings (C22) are nearly perpendicular to the naphthyl ring with the dihedral angles of 84.73° and 73.60°, respectively, which further results in the formation of the intramolecular C–H⋯π interactions between the naphthyl ring and the benzene ring. In addition, there are numerous intermolecular π⋯π and C–H⋯π interactions among the aromatic rings from neighboring molecules, which results in the formation of two-dimensional (2D) supramolecular layers. Meanwhile, these 2D layers are further assembled by the π⋯π stacking interactions between the naphthyl rings, C–H⋯π interactions between the quinoline unit and benzene ring, and C–H⋯O hydrogen bonding interactions between the sulfanilamide oxygen atoms and the naphthyl rings to generate the final three-dimensional (3D) supramolecular structure.
