Description
Technical field
The present invention relates to a kind of preparation and application of photoswitch fluorescent nano material, it particularly relates to be adjustable to stabilization
The compound photoswitch nano-particle of white light, belong to chemical material preparation.
Background technology
In past ten years, in the design and synthesis of various photoswitch fluorescent materials, have photochromic and can
The material of inverse fluorescent switch performance be considered as one kind can be applied to high-density optical storage, false proof, encryption, complex biological system into
The new material of picture.This photoswitch fluorescent material is generally by by the acceptor of a kind of donor fluorescent dye and corresponding level-density parameter
Photochromic compound (such as oxazine compound, spiro-pyrans class compound and azobenzene compound) is connected by covalent bond
Connect, the mode such as physical absorption is attached in nano-particle, excite the lower fluorescence property to particle to carry out not sharing the same light so as to realize
Reversible regulation and control.Compared with the traditional colour solid of photoswitch fluorescent organic molecule two or three colour solids, photoswitch nano-particle has following
Multiple advantages：(1) more preferable water dispersible and biocompatibility；(2) higher fluorescent brightness and photostability；(3) can apply
, can be by noise separation by warbled signal in complex system.These advantages cause photoswitch nano-particle in height
