  Synthesis of new fluorescent 1-(thien-2-yl)-9H-thieno[3,4-b]-chroman-9-ones and their fluorescent photomodulation by photochromic dihetarylethenes

  摘要：

  New fluorescent derivatives of 1-(thien-2-yl)-3-methyl-9H-thieno[3,4-b]-chroman-9-one are synthesized and their spectral properties studied. The prepared fluorescent compounds are combined with several photochromic benzothienyl dihetarylethenes to provide mixed systems exhibiting reversible photo-induced fluorescence modulation in solution. The obtained results are promising for the development of polymeric photochromic recording media with a non-destructive fluorescence readout of optical information for RAM with extra large information capacity.
