A new compound 4-[(trans-(2-pyridyl))styryl]-N,N-dibutylbenzenamine has been synthesized and characterized by elemental analysis,UV,and X-ray single-crystal diffraction studies.The compound crystallizes in the triclinic system with space group P-1,a=1.15041(3) nm,b=1.45746(4) nm,c=1.51598(4) nm,Z=4,V=2.33068(11) nm3,R1=0.0962,wR2=0.2630.The result showed that the molecule with donor,π-conjugated bridge and acceptor(D-π-A) structure has good planarity,which results in effective electronic delocalization and increased intramolecular charge transfer.The molecules are linked by intermolecular C-H…π.It is believed that π electrons play a significant role for their packing,which attributed it with higher Stock shifts in photoluminescence properties.
