- the spin coater rotation speed during film formation was 4000 rpm, and the film thickness was about 10 O nm.
- EL light emission having a peak at 620 nm was obtained.
- the device emitted 100 cdZm 2 at about 7.2 V.
- the maximum luminous efficiency was 0.7 cd / A.
- a device was produced in the same manner as in the above example, except that iridium complex B was not added to polymer compound 1-4. By applying a voltage to the obtained device, EL light emission having a peak at 452 nm was obtained. This device, about 7. showed light emission of 100 c DZM 2 at 7 V, the maximum Luminous efficiency was 0. 5 c dZA.
- the resulting precipitate was collected by filtration.
- the precipitate was dried under reduced pressure to obtain 4 g of a polymer.
- This polymer is called a polymer compound.
- the polystyrene reduced weight average molecular weight of the obtained polymer compound was 4.6 ⁇ 10 4 , and the number average molecular weight was 6.5 ⁇ 10 3 .
- High molecular compound 1-1 5 Copolymer consisting essentially of the following repeating units
- a device was fabricated in the same manner as in Example 1 except that Polymer Compound 1-5 was used instead of Polymer Compound 1-1.
- the spin coater rotation speed during film formation was 1400 rpm, and the film thickness was about 95 nm.
- EL light emission having a peak at 516 nm was obtained.
- the device emitted 100 cd / m 2 at about 8.5 V.
- the maximum luminous efficiency was 6.2 cd / A.
- a device was prepared in the same manner as in the above example, except that iridium complex A was not added to the polymer-conjugated product 115. By applying a voltage to the obtained device, EL light emission having a peak at 444 nm was obtained. The device emitted 100 cdZm 2 at about 6.1 V, and had a maximum emission efficiency of 0.6 cd / A. Industrial applicability
- a light-emitting element using the composition of the present invention for a light-emitting layer has excellent luminous efficiency. Therefore, the composition of the present invention can be suitably used as a light emitting material of a polymer LED, and can be used as a material such as a polymer light emitting device and an organic EL device using the same.
