Source of material

The title compound was one-pot synthesized by heating a mixture of 4,4′-dimethoxybenzophenone and (1R,2R)-(+)-1,2-diphenylethylenediamine in acetic acid [4]. White needle crystal of the title compound was obtained through solvent evaporation method from a mixed solvent of trichloromethane and methanol 1:1 at room temperature.

Experimental details

The hydrogen atoms were assigned with common isotropic displacement factors Uiso(H) = 1.2 times Ueq(C, aromatic ring), and Uiso(H) = 1.5 times Ueq(C, methyl). The final refinement by using geometrical restraints, with C—H = 0.93 Å (aromatic ring), and C—H = 0.96 Å (methyl).

Comment

Since the aggregation induced emission (AIE) phenomenon was reported for the first time in 2001 [5], AIE molecules have been widely used in OLED, fluorescence sensors, biosensors and cell imaging and further applications [6], [7], [8], [9], [10]. Very recently, tetraphenylpyrazine (TPP), as a new AIE core, has attracted much interest due to its advantages of easy preparation, facile modification, excellent stability and tunable light emission [11], [12], [13], [14], [15], [16], [17].

Bartnik and co-workers reported the dimorphism of TPP in 1999, with crystallographically imposed symmetry of the title molecules in both modifications [17]. In the title structure the molecules occupy a general position (cf. the figure). The dihedral angle between the planes defined by C5—C10 and C12—C17 is 50.9°, and two phenyl rings defined by C19—C24 and C25—C30 form a dihedral angle of 61.1°. In addition, bond angles of C15—O1—C18 and C8—O2—C11 are 118.72(19)° and 119.36(19)°, respectively. Bond lengths and angles are all in the expected ranges.
