摘要:Described herein are C 5 -C 6 annelated naphthopyrans that possess at least one electron-withdrawing group. The compounds possess desirable properties such as increased fading kinetics. Also described herein are new methods for synthesizing 2H-chromenes annelated at C 5 -C 6 . The methods involve less stringent reaction conditions as well as provide increased reaction yields. The methods permit the synthesis of a wide variety of substituted naphthopyrans that can be temperature sensitive, which was not possible with previous synthetic routes.

摘要:Disclosed is a material for organic EL devices which is high in synthesis yield and luminous efficiency while having long emission life. Also disclosed are an organic EL device using such a material, and a display and illuminating device using such an organic EL device. The organic EL material is composed of a metal complex having a partial structure represented by the general formula (1) below, and is characterized by having at least one substituent in a ligand part which suppresses bidentate coordination.
