Description

A kind of environment sensitive dyestuff and its preparation method and application
Technical field
The present invention relates to fluorescent material technical fields, more particularly to a kind of fluorescent material with environment sensitive.
Background technique
The dyestuff of environment sensitive can change the variation of luminescent color or intensity response environment, such as polarity, pH and viscosity etc. (also referred to as molten cause chromotropic dye).This characteristic makes them be widely used in fluorescence probe, chemical sensor, micro-environmental variation inspection Survey, bio-imaging, molecular switch and the mutually fields such as separation visualization.
Environment sensitive dye molecule is mainly realized by forming Intramolecular electron transfer state.When dyestuff is excited by light Afterwards, charge is transferred to acceptor groups from donor, generates the excitation state with high dipole moment.Then, excitation state by with solvent pairs Extremely sub interaction and relax, therefore red shift occurs in polar solvent for its fluorescence peak, and corresponding color is moved to feux rouges direction It is dynamic.In general, the requirement of environment sensitive dyestuff is: (1) having big Stokes shift to avoid self absorption effect;(2) With the variation of environment, acute variation occurs for fluorescence color;(3) high luminescence generated by light quantum is all had in varying environment to produce Rate.Usually there is distortion charge transfer state and the molecule of plane charge transfer state to be commonly used for environment sensitive dyestuff.With distortion The molecule of charge transfer state has big Stokes shift and violent color change, but quantum yield in different environments There is very big difference.Such as in polar solvent, quantum yield can significantly decay or even fluorescence disappears.Opposite, have The molecule of plane charge transfer state all has higher quantum yield in varying environment, but its color change is not obvious enough.
In addition, the dye molecule of environment sensitive usually has the aromatic ring of conjugation.Such molecule can generate by force in state of aggregation Intermolecular pi-pi accumulation interaction, cause its fluorescence to be quenched, such as solid environment measuring and phase structure can not be applied to The fields such as visualization.Therefore, developing while having the luminescent dye molecule of solution and state of aggregation environment sensitive is to have extensively Application prospect.
Summary of the invention
In view of the foregoing drawbacks, the environment sensitive dye molecule new technical problem to be solved by the invention is to provide one kind, It has and all has the advantages that sensibility to microenvironment in solution state and state of aggregation, and furthermore in solution state, being used as, polarity is quick When infection material, higher fluorescence quantum yield is all had in different solvents.
