Researches on α-cyanostilbene derivatives demonstrated them to be promising AIE or AIEE structural molecules and potential photoelectric materials. One novel α-cyanostilbene derivative, namely(E)-2-(4-butoxyphenyl)-3-(4-(diethylamino)phenyl)acrylonitrile(BPDPA), has been designed, synthesized and characterized. The crystalline structure of BPDPA has been studied in detail. The single-crystal X-ray diffraction revealed BPDPA crystallizes in triclinic space group P1, with a = 12.860(5), b = 13.327(5), c = 15.016(5) , α= 72.650(5), β = 66.969(5),γ = 62.897(5), Mr = 696.95, V = 2085.6(13) 3, Z = 2, Dc = 1.110 g/cm-3, μ = 0.068 mm-1, F(000) = 752, Rint = 0.0264, R(I > 2σ(I)) = 0.0649, wR(I > 2σ(I) = 0.1724, R(all data) = 0.1321, wR(all data) = 0.2158, completeness to theta = 25.00 is 99.4% and GOF = 1.067. Like most reported α-cyanostilbene derivatives, BPDPA possesses a somewhat twisted molecular structure. UV-Vis and FL measurements showed an obviously bathochromic effect of BPDPA with increasing the polarity of the solvents.

Mostly reported α-cyanostilbene derivatives, BPDPA possesses a somewhat twisted molecular structure. Vis and FL measurements showed an obviously bathochromic effect o f BPDPA with increasing the polarity of the solvents.
