Description
Technical field
The present invention relates to electroluminescent technology field more particularly to a kind of indeno acenaphthylene analog derivative and preparation method thereof and
Luminescent device.
Background technology
Organic luminescent device (OLED) is made of the organic matter layer being inserted between cathode, anode and cathode and anode,
Wherein, organic layer is generally made of multilayered structure, such as include hole injection layer, hole transmission layer, luminescent layer, electron transfer layer and
Electron injecting layer etc.；Its effect is to improve the efficiency and stability of organic electroluminescence device.
Present Portable Displays lead to the higher consumption of benchmark Portable Displays requirement with the increase of panel size
Electric power.Thus, the battery of limited power supply source is difficult meet demand in Portable Displays, and uses organic electroluminescent
When device, efficiency and service life are must to solve the problems, such as.Efficiency and service life, driving voltage are coherent mutually, and general efficiency increases
Start voltage reduction, and organic matter can be caused by starting the resistance heating (Joule heating) occurred when voltage reduction driving
It crystallizes, as a result service life increased tendency.But improve the efficiency that above-mentioned organic layer is unable to organic electroluminescence device.Because respectively
Energy level and T1 values, the inherent characteristic of substance between organic layer（Degree of excursion, interfacial characteristics etc.）It can be only achieved and prolong when equal optimal combination
Long light-emitting device life period and raising efficiency of luminescent device purpose.
Traditional hole transmission layer develops the fast object of hole degree of excursion (hole mobility) to reduce driving voltage
Matter develops packing density (packing density) high HOMO valences to improve hole degree of excursion and is connect with luminescent layer HOMO valences
Close substance, but degree of excursion fast substance in hole generally results in the efficiency reduction of luminescent device.Because of organic electroluminescence device hole
When degree of excursion is faster than electronics degree of excursion (electron mobility), it may appear that electronics is unbalanced (charge unbalance)
Phenomenon eventually leads to the problem of luminous efficiency reduction and service life reduction.And use packing density (packing density) low
Substance reduces hole degree of excursion, and then adjusts the electronic equalizing situation in luminescent layer, but will appear low packing density
(packing density) and then driving voltage is improved, and the raising of driving voltage can increase electronics heating and shorten device lifetime,
Therefore it provides a kind of hole transport layer material makes it not only increase its service life applied to electroluminescent device, but also improve its hair
Light efficiency is current problem to be solved.
