1 - (2 - hydroxyethyl) - 3, 3 - dimethyl indole moiety - 6 '- nitrobenzene and screw pyran is a tri-state photochromic compounds, can respond to the chemical optical input to produce optical output under the irradiation of ultraviolet light, colorless screw pyran configurations (SP) can be converted into purple cyanine of configurations (ME) in addition, acidification of the SP converted to yellow-green proton department cyanine (MEH). When the irradiation with visible light, color ME and MEH is converted into a colorless SP state in the same way, the ME stored in the dark state can be converted to SP ME adding acid to generate MEH,MEH base changes back to ME after treatment. These studies on molecular application properties are being actively carried out.
