Abstract

The invention relates to an acenaphthylene derivative of which structure is shown in formula I. The acenaphthylene derivative designed in the invention has the unique structure that the color of the derivative can be red, yellow or blue by regulating the bridging position of the thiophene of the acenaphthylene derivative under the irradiation of lights of different wavelengths. The acenaphthylene derivative of the invention can applied in the fields of building decoration, special protection, full color display, multi-dimensional information storage and readout and the like. In the formula I, R1, R2 and R3 are respectively one of hydrogen, alkyl group, aryl group, halogen, hydroxyl group, aldehyde group, carboxyl group, sulfonic group, -COOMe and -SO3Me(Me is metal); n is an integer between one to three and m is an integer between one to three.

Description

technical field

[0001] The present invention relates to an acenaphthylene derivative. Background technique

[0002] Among many organic photochromic materials, due to the good thermal stability of diarylethene (-20-80 ℃ no configuration transformation for a long time); ); high closed-loop quantum efficiency (mostly can reach more than 30%); fast response time (switching ring is between several picoseconds), and it is considered to be possible to meet the high potential of high speed and large capacity One of the storage materials. Due to the series of useful properties of dithienylethylene, scientists have devoted a lot of enthusiasm and energy in designing and synthesizing these compounds in recent years. The purpose of these research and development, on the one hand, is to expect to construct new molecular materials that may have advanced or new properties; match the condition.

[0003] Although many molecular materials in this area have been researched and developed, e...
