Preparation of Photosensitive Crown Ether Styryl Dye
감광성 Crown Ether Styryl 염료의 합성
Abstract
A Photosensitive Crown Ether Styryl Dye derivative(CESD) was prepared for the application and the structure of it was discussed. Light excitation causes the trans-cis isomerization of CESD yielding a conformation suitable to form a coordination bond between an anion group and a metal cation located in crown ether. Intermolecular complex stabilized the cis isomer that absorbs at a shorter wavelength in the trend-cis isomerization. Application of CESD was suggested.
