Abstract

The invention discloses a red solid fluorescent luminescent material shown as a formula (I) and a preparation method and an application thereof. In the formula (I), R is selected from -CH3 or -CH2CH2CH3 or -CH2Cl or -CH = CHCOOH.

Description

Technical field: [0001] The invention relates to a red solid fluorescent luminescent material and a preparation method thereof. Background technique: [0002] The design and synthesis of red fluorescent light-emitting materials play an important role in basic research and application fields. In terms of the application of complex bioassay systems, the emission wavelength of red fluorescent light-emitting materials can penetrate thick samples, such as skin, making it of great scientific significance and application value in in vitro and in vivo experiments (Aggregation-Induced Emission: Fundamentals (2014 ), 155-167, 2plates). In addition, red solid fluorescent materials also play an important role in the research field of organic light-emitting diodes (Angew. Chem. Int. Ed. 2015, 54, 13068–13072). [0003] At present, there are few organic light-emitting small molecules with red solid fluorescence properties reported in the literature, mainly: DTPA-FO and TPA-FOCN with 2.7...
