Description

The platinum complex of four-coordination deuterated ligand coordination

Technical field

The disclosure be on one kind be adapted to show and illuminate application in be used as phosphorescence or delayed fluorescence or The platinum complex of the multiple tooth coordination of phosphorescent emitters.

Background technology

The compound that can be absorbed and/or light is applicable to various optics and photoelectric device, includes but is not limited to such as Solar energy, photosensitive such light absorption device, Organic Light Emitting Diode (OLED), light emitting devices or existing light absorbs have light again The device of emissivities and the related application for biomarker.In order to find for the organic of optics and electroluminescent device And organo metallic material, specially made much to study.In general, the research mesh village in this field is to realize multinomial target, Absorption and luminous efficiency including improving device, improve the stability of device, and improve resolution ratio etc..

Although exclusively for optics and photoelectric material (for example, red and green phosphorescent organo metallic material is on sale on the market And Organic Light Emitting Diode (OLED), illumination and advanced display in be used as phosphor) studies conducted achieve it is aobvious The progress of work, but many currently available materials show many shortcomings, including combination property is general, transmitting or incomplete absorption And stability is not ideal enough etc..

Excellent BLUE EMITTER is especially rare, and its a major challenge faced is the stability of blue device.With it is red and The minimum triplet excited state energy of green phosphor is compared, and the minimum triplet excited state energy of blue phosphor is very high, this meaning The minimum triplet excited state energy for the material of main part of blue device even can be higher.Therefore, one of problem is that blue device can Dopant material is limited.Accordingly, it is desirable to the new of more dominance energy can be shown in optical emitting and absorption application Material.

In the present disclosure of the invention, deuterium is introduced to the part of platinum complex.Because D-atom is than hydrogen atom weight, with C- H keys are compared, and the vibration of carbon-deuterium (C-D) key can be reduced.Therefore, the shuttle belt of emission spectrum will be reduced or weakened, and whole light Spectrum can narrow.This is possible to promote transmitting performance that is photochromic and improving device.More particularly, the CIE coordinates of complex compound will It is tuned to more meet the demand of flat panel TV.

The content of the invention

The present invention relates to the gold as emitter being adapted in Organic Light Emitting Diode (OLED), display and illumination application Belong to complex compound.

Just become to be becoming increasingly popular using the phototube device of organic material, and they it is welcome the reason for have a lot. Many materials for manufacturing this device are relatively cheap, thus organic electro-optic device relative to inorganic device have it is potential into This advantage.In addition, the inherent characteristic of organic material, such as its pliability, may make them be very suitable for some special applications, such as Processing in flexible substrate.The example of organic photoelectric device device includes organic luminescent device (OLED), organic transistor, You Jitai Positive energy battery and organic photodetector.For OLED, organic material may have the advantage in performance compared to traditional material. For example, the luminous wavelength of organic luminous layer can generally be easy to be adjusted with appropriate dopant.

Decay of the exciton from singlet excited to ground state produces cold light, i.e. fluorescence.Exciton is from triplet excited state to ground state Decay produces cold light, i.e. phosphorescence.Because the strong spin-orbit coupling energy of heavy metal atom effectively strengthens singlet excited Intersect (ISC) between system between triplet excited state, phosphorescent metal complex, such as platinum complex have shown that they are harvested Both substance and triplet excited state and the potentiality for reaching 100% internal quantum.Therefore, phosphorescent metal complex is conduct The fine candidate material of organic luminescent device (OLED) light emitting layer dopant, it is very more all to obtain in academic and industrial circle Attention.And in the past ten years, people achieve necessarily on the commercialized road of technological direction high profit Achievement, for example, OLED is applied in the advanced display of smart mobile phone, television set and digital camera.

However, up to the present, blue electroluminescent devices are still the most field of challenge, reason in this technology At least partly it is the unstability of blue device.It is generally believed that the selection of host material is the one of the blue device stability of influence Individual factor.But, the minimum triplet excitation state (T of blue fluorescent material₁) energy it is very high, this generally means that blue device Host material minimum triplet excitation state (T₁) energy should be higher.This just brings to the blue device substrate material of exploitation It is difficult.

The present invention provides a kind of design of material route by the way that D-atom (s) to be introduced to the part of platinum complex.Due to deuterium Atomic ratio hydrogen atom weight, compared with c h bond, the vibration of carbon-deuterium (C-D) key can be reduced.Therefore, the shuttle belt of emission spectrum will Reduce or weaken, and whole spectrum can narrow.This is possible to promote transmitting performance that is photochromic and improving device.
