Embodiment Construction

[0040] The present invention provides a light-emitting organic semiconductor framework material, which can effectively solve the difficulty of balancing light emission and charge transport in the design of light-emitting organic semiconductor materials, specifically including the following two points:

[0041] ① The research on the nature of the relationship between fluorescence quantum efficiency and carrier mobility of aggregated materials needs to go deep into the level of intermolecular interactions behind the microscopic stacking structure, so as to clarify the dependence between the two;

[0042]②Introducing heteroatoms such as N and O at the same time in the appropriate position in the fused ring system will strengthen the C-H...π interaction, hydrogen bond interaction and local dipole-dipole interactions between adjacent molecules, and promote the compactness of microscopic aggregated molecules. Stacking ensures the carrier transport performance. Through the strengthen...

Abstract

The invention discloses a luminous organic semiconductor framework material as well as applications: by arranging heteroatoms, such as N, O and S, on the same end of an aromatic fused ring, the molecule is induced to generate static dipole moment; then through the intermolecular forces, such as intermolecular hydrogen bonds, dipolar-dipolar interaction and the like, the stacking microstructure ofthe molecule under aggregation state, the luminous performance of the material, emitting color of the material, and carrier transport performance of the material are regulated. The product has excellent luminescence property under aggregation state.

Description

technical field [0001] The invention belongs to the technical field of light-emitting organic semiconductor materials, and in particular relates to a light-emitting organic semiconductor framework material and applications thereof. Background technique [0002] Organic electronics with organic conjugated molecules as the core is currently an important international frontier research field. The organic optoelectronics industry has become an important support point to promote international economic development, and it is also one of the strategic emerging industries supported by our country. Organic light-emitting transistors (Organic light-emitting transistors, OLETs) combine the light-emitting function of OLEDs and the switching function of OTFTs, and will replace active matrix driven OLEDs (AMOLED) in the future. Integrated light sources, optical communications, and Electromechanical pumping laser and other fields have important application prospects and become the new favo...
