摘要: 通过缓慢挥发溶剂法得到一种不对称吡喃方酸菁染料的单晶,测定了其晶体结构.其晶系为三斜晶系,空间群为P1,a=0.9228(4),b=1.4122(6),c=0.6124(3)nm,α=93.97(4),β=98.14(5),γ=71.05(4),V=0.7470(6)nm3,Z=1.用晶体结构数据解释了此不对称染料的1H-NMR谱.

Abstract: The crystal structure of 2-[1-(2,6-di-t-butyl-4H-pyran-4-ylidene)-ethyl]-4-[1-(2,6-di-t-butyl-4H-pyran-4-ylidene)-methyl] cyclobutenediylium-1,3-diolate was determined.It was found that the crystal system is triclinic and the space group is P1,with a=0.9228 (4),b=1.4122 (6),c=0.6124 (3) nm with α=93.97 (4),β=98.14 (5),γ=71.05 (4)º,V=0.7470 (6) nm3 and Z=1.1H-NMR spectra of the title compound were interpreted by the data of single crystal structure.

Key words: pyrylium-squarylium, cyanine dye, single crystal, crystal structure, 1H-NMR spectra
