| Abstract: | 3,5-Bis(4-methylphenyl) pyridine(1) with yield of 73% was synthesized by Suzuki cross-coupling reaction, using 3,5-bromide pyridine and 4-methylphenyl boronic acid as materials and palla-dium acetate as catalyst. The structures and properties were characterized by 1 H NMR, 13 C NMR, IR, elemental analysis, UV-Vis, FL and X-ray single crystal diffraction. The results showed that 1 (CCDC:1509844) belongs to orthorhombic system and space group P212121 with a=6. 4478(12) ?, b=7. 2402(14) ?, c=29. 8900(6) ?,β=90°. 1 was a non-planar, rigid and conjugated mol-ecule with photoluminescence quantum efficiency of 13 . 9%. |
