Problems solved by technology

However, the fluorescence emission intensity of these traditional organic light-emitting materials is usually very weak in the solid state or aggregated state, that is, the ACQ phenomenon, which is unfavorable for the observation of the MFC phenomenon, resulting in low solid-state luminous efficiency of these materials, and the color contrast is not obvious

Abstract

The invention discloses a barbituric acid type compound of tetra-substituted thiophene and a preparation method of the barbituric acid type compound. A chemical structural formula is as follows: the formula is shown in the description. The barbituric acid type compound based on the tetra-substituted thiophene is synthesized for the first time, and an experiment finds out that the compound has relatively high solid-state luminous efficiency and remarkable color contrast.

Description

technical field [0001] The invention relates to the field of aggregation-induced fluorescence (AIE) compounds, in particular to a tetrasubstituted thiophene barbituric acid compound and a preparation method thereof. Background technique [0002] In 2001, Professor Tang Benzhong's research group discovered a peculiar phenomenon: some silole molecules hardly emit light in solution, but the light emission is greatly enhanced in the aggregated state or solid film. Because this luminescence enhancement is caused by aggregation, this phenomenon is vividly defined as "aggregation-induced emission (AIE)". [0003] Stimuli-responsive materials are one of the future development trends of high-tech materials and play an important role in modern high-tech. Mechanochromic (MFC) materials change their solid-state emission colors in response to external mechanical stimuli (e.g., grinding, compression, shearing, stretching, friction), and may be used in pressure sensors, optoelectronic dev...
