Description
Technical field
The invention belongs to nonlinear optical material field, it is related to a kind of photochemistry and removes oxygen to protect the triple of photosensitizer
The method and its application of excitation state.
Background technology
Triplet：Photosensitizer molecule in ground state, absorbs the exciting light of specific wavelength, and molecule jumps from ground state absorption energy
Singlet excited is adjourned, later due to the rigidity of molecule itself or molecule and heavy metal coordination, due to depositing for heavy metal effect
Under, intersystem crossing can occur for intermolecular energy, from singlet excited to triplet excited state.If molecule is directly from substance
Emitted energy returns to ground state to excitation state in the form of light, this process is fluorescent emission, and the service life is usually that nanosecond is other, if
Molecule transits to triplet from singlet excited, and from triplet, emitted energy returns to ground state in the form of light, this process is phosphorus
Light emitting.It is to violate spin rule due to transitting to triplet excited state from singlet excited, when this process needs certain
Between, thus the service life of phosphorescence for the service life of fluorescence, can big several orders of magnitude, generally microsecond rank.
Since the service life of phosphorescence can reach microsecond rank, the molecule oxygen in air is on energy level and symmetry and phosphorescence phase
Matching, therefore phosphorescence is easy to be quenched by the oxygen in air, makes the energy transfer of phosphorescent molecules triplet to oxygen, molecule
After oxygen receives the energy excitation of phosphorescence, from triplet transition to singlet state.Creating singlet oxygen is due to energy ratio molecule oxygen
Height, thus it is more unstable, it is easier to and oxidation occurs for organic compound, destroys organic matter.And the energy of phosphorescence is not logical
The form transmitting of light is crossed, but is quenched by oxygen, therefore phosphorescence is not easy to be detected under aerobic conditions.Phosphorescence biology at
Picture, OLED and organic compound identification etc. have boundless application, therefore phosphorescence is protected not quenched very by oxygen
It is significant.
Colloidal particle or macromolecule in colloidal sol or solution interconnect under certain condition, form space net structure,
It (can also be gas in xerogel, xerogel is also referred to as airsetting to be filled in structural void as the liquid of decentralized medium
Glue), such a special dispersion is referred to as gel.There is no mobility.It is internal often to contain big quantity of fluid.Inside gel
There is fine and close reticular structure, the transmission of solvent and molecule oxygen can be limited, therefore gel can be relatively good as one
Medium protects phosphorescence.Preparation process in terms of general gel is used to protect phosphorescence is under vacuum to be added to gelling agent
In solvent containing photosensitizer, by dissolving by heating gelling agent, after temperature cools down, gel is formed.
Conversion refers to that the donor in ground state is in laser or other light sources in spy on T-T annihilation photon
Under the irradiation of standing wave length, energy jump is absorbed to singlet excited, triplet excited state, Zhi Houyu are reached by intersystem crossing later
Acceptor molecule in ground state carries out energy transfer by collision, is given in triplet excited state in ground state by absorption is known from experience
The energy of body, from ground state transition to triplet excited state, the triplet excited state molecule of two receptors can collide with each other acceptor molecule
Realize energy transfer, it is possible to cause one of receptor to transit to singlet excited from triplet excited state, swash later from substance
Hair state sends out fluorescence and returns to ground state, another molecule for being in the receptor of triplet excited state is returned directly to after energy transmission is complete
Ground state.Here it sends out receptor and sends out the wavelength of fluorescence and be less than the wavelength of incident light.Due to the energy density of required exciting light
Low (usually less than 100mW/cm2), the advantages that absorbing ability is strong, upper conversion quantum yield is high, excitation-emission Wavelength tunable, TTA
Upper conversion is in field of solar energy utilization, three-dimensional mangement, fluorescent molecular biomarker and the high-tech areas such as photodynamics is for cancer
Show good application prospect and high additive value.
