PHOTOCHROMIC COMPOUND, TEMPERATURE SENSOR MATERIAL, TEMPERATURE PROBE MATERIAL, OXYGEN CONCENTRATION SENSOR MATERIAL AND OXYGEN CONCENTRATION PROBE MATERIAL

PROBLEM TO BE SOLVED: To provide a photochromic compound that can show light emission in both isomers and has temperature responsiveness and oxygen concentration responsiveness. SOLUTION: A photochromic compound is represented by the following formula (1). (where, A and B are substituents as electron donating groups. Z1 and Z2 are each a substituent selected from hydrogen or an electron acceptor group). SELECTED DRAWING: Figure 4 COPYRIGHT: (C)2018,JPOandINPIT

Synthesis and Characterization of Electron-Deficient Asymmetrically Substituted Diarylindenotetracenes

Electron-deficient asymmetrically substituted diarylindenotetracenes were prepared via a series of Friedel-Crafts acylations, aryl-aryl cross-couplings, and an intramolecular oxidative cyclization to form the indene ring. Single-crystal X-ray experiments showed good π-π overlap with π-π distances ranging from 3.26 to 3.76 ?. Both thermogravimetric analysis and differential scanning calorimetry indicated that asymmetrically substituted indenotetracenes (ASIs) are stable at elevated temperatures. From cyclic voltammetry experiments, HOMO/LUMO energy levels of ASI derivatives were determined to be near -5.4/-4.0 eV. UV/visible absorption spectra showed strong absorption of light between 400 and 650 nm with molar attenuation coefficients from 104 to 105 M-1 cm-1. ASIs were also found to have very low fluorescence quantum yields, less than 4%. Using the solid-state packing determined from the single-crystal X-ray experiments, computational modeling indicated that ASI molecules should favor electron transport.

A photochromic phenoxyquinone based cyanide ion sensor

We have developed a new chemosensor system for cyanide ion that is based on a photochromic material. We observed that addition of cyanide anion to a UV irradiated solution of a phenoxynaphthacenequinone derivative brought about a significant change in the absorption spectra that enabled detection of cyanide ion in a selective and sensitive manner. A carbanion intermediate was shown to be responsible for the long wavelength absorption band (630-940 nm) that is generated by cyanide addition.
