Description
Technical field
The present invention relates to technical field of organic luminescence materials, and in particular to a kind of organic with 3- phenyl isoquinolin quinoline structures
Metal complex materials and luminescent device.
Background technology
Organic Light Emitting Diode (Organic Light Emitting Diode), i.e. OLED refer in forward bias voltage drop electricity
Electric energy is converted into light by organic molecule, metal-organic complexes or polymer molecule luminescent material under the action of
A kind of luminescence phenomenon of energy.OLED due to it with fast response time, driving voltage is low, luminous efficiency and high resolution, comparison
Degree is high, visual angle is wide, and is from main light emission, the features such as without backlight, thus by academia and the extensive concern of industrial quarters.
In addition it can also be produced on the even flexible plastics of cheap glass, metal, therefore also has that at low cost, production technology is simple
List can carry out the advantages that large area production, it has also become full-color display of new generation and lighting engineering are consolidated in full-color display and plane
State lighting area has wide and huge application prospect.

It is in the molecule of singlet afterwards, spin statistics quantum shows that its theoretical internal quantum is only 25%.There is 75% to be excited
Molecule is in excited triplet state, and phosphorescence can be sent out by returning to ground state by radiation transistion, and general organic molecule chemical combination
Object is difficult to send out phosphorescence at room temperature.Until the electrophosphorescence for being found that metal-organic complexes material at room temperature shows
As, using the strong spin(-)orbit coupling of heavy metal atom can effectively facilitate electronics by singlet to triplet state be leap up more
(ISC), produced all singlets and triplet state exciton (exciton) are electrically excited so as to which OLED device can make full use of,
The theoretical internal quantum of luminescent material is made to can reach 100%.So far the research of luminous organic material is made to enter one entirely
New period.
Red phosphorescent complex of iridium still has the problem of luminous quantum efficiency is low, excitation purity is poor at present.Cause this shape
The main reason for condition be because feux rouges comes from Yue Gan between the relatively narrow energy level of energy gap, and the heavy metal complex of low energy gap into
There are certain difficulty during row ligand design, secondly in red light material system there is the interaction of stronger pi-pi bond, ligand it
Between have very strong charge transfer characteristic, so as to make the presence of more radiationless relaxation channels in narrow band gap, exacerbate phosphor
Quenching, reduce the quantum yield of feux rouges system.Therefore the red phosphorescence material of design synthesis high comprehensive performance, will become
The important topic of electroluminescent organic material research.
To sum up, existing red emitting material there are excitation purity it is insufficient, be difficult to realize the defects of industry chemical conversion production etc..In view of
This, spy proposes the present invention.
