Chemistry Letters   47(4) 536-539   2018   [Refereed]
<p>We have developed a new photochromic material containing a stilbene moiety and a urea moiety based on cooperative effect of photoisomerization and proton transfer. An anthracene–urea–stilbene compound (stAn) exhibited cis-to-tr...

Chemistry Letters   47(4) 483-486   2018   [Refereed]
<p>We investigated the excited state intermolecular proton transfer of pyrene–urea compounds, 1PUP and 4PUP, followed by a tautomer formation in the presence of an acetate ion. The drastic red-shift and enhancement of fluorescence in...

PHOTOCHEMISTRY AND PHOTOBIOLOGY   93(5) 1187-1192   Jun 2017   [Refereed]
A new photoreaction mechanism of Three-state molecular switch fluorescence sensor based on ON1-OFF-ON2 sequence was achieved by anthracene-diurea compound, which was designed using two phenylurea groups and one anthracene, 9,10BtDSPUA. Photochemic...

Org. Biomol. Chem.   15(31) 6575-6583   Jul 2017   [Refereed]
We report anthracene-diurea compounds which behave as anion sensors based on the fluorescence emission regulated by the substitution position on the anthracene ring. Anthracene-diurea compounds exhibit different excited-state intermolecular proton...

Inorganic chemistry   56(15) 8726-8729   Aug 2017   [Refereed]
Compounds with controllable color emissions are potentially useful as photoluminescent materials in imaging and sensing applications. Multimolecular emission can be used realizing variable-color emitters and has been demonstrated in the solid stat...

We synthesized anthracene-urea compounds (9An and 2An), a pyrene-urea compound (Py) and an anthracene-diurea compound (9,10An), all of which have one or two alkylsulfonyl groups to improve their solubility in various organic solvents. Consequently...
