本文报道了2,3-双(1,2-二甲基-3-吲哚基)-2-丁烯(DF1),2,3-双(1,4-二苯基-2-甲基-3-吡咯基-2-丁烯(DF2),2,3-双(1-对甲苯基-4-苯基-2-甲基-3-吡咯基)-2-丁烯(DF3),2,3-双(1-对溴苯基-4-苯基-2-甲基-3-吡咯基)-2-丁烯(DF4)和2,3-双(1-甲氧苯基-5-苯基-2-甲基-3-吡咯基)-2-丁烯(DF5)的合成,以及它们的光致变色行为的研究。特别是DF1和DF5的光呈色和光消色过程进行了较为细致的研究。

Five heterocyclic diarylethenes, 2,3-bis(1,2-dimethyl-3-indolyl)-2-butene (DF1), 2,3-bis(1,4-diphenyl-2-methyl-3-pyrryl)-2-butene (DF2), 2,3-bis(1-p-methylphenyl-4-phenyl-2-methyl-3-pyrryl)-2-butene (DF3), 2,3-bis( 1 -p-bromophenyl-4-phenyl-2-methyl-3-pyrryl)-2-butene (DF4), and 2,3-bis(1-p-methoxyphenyl-5-phenyl-2-methyl-3-pyrryl)-2-butene (DF5), were synthesized. Their photochromic behaviour, especially photocolouration and photobleaching of DF1 and DF5, were discussed in detail.
