Tj. Kang et al., PHOTOCHROMIC DISPIRONAPHTHOXAZINE POLYETHERS - SYNTHESIS AND THEIR CATION-BINDING CAPABILITY, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 278, 1996, pp. 181-188
Dispironaphthoxazines incorporating polyether chain were synthesized.
Photochromic effects on cation binding capability of the molecules wer
e investigated. Due to the photochromic spironaphthoxazine unit in the
se compounds, complexation with metal cations is easily identified by
the conventional spectroscopic method. Cation binding ability of dispi
ronaphthoxazine with tetraethylene glycol unit is enhanced under the U
V light irradiation. This type of photochromic compound may work as a
photoresponsive ionophore.
