Abstract

The invention relates to a perylene diimide fluorescent dye with ortho-substituted benzoanthrone, which uses 3,4,9,10-perylenetetracarboximide as the core group, and the acyl diimide at both ends of the core group 7-tridecyl groups are connected to the imine nitrogen atoms, and benzanthrone is connected to the ortho position of the core group. In the present invention, a 7-tridecyl group is introduced into the perylene diimide group and a benzanthrone group is introduced into the ortho position, and the obtained perylene diimide fluorescent dye of the ortho position substituted benzanthrone has a large bis The photon absorption cross section greatly improves the third-order nonlinear optical activity, and can be applied to third-order nonlinear optical materials. Simultaneously, regardless of using single-photon or two-photon to excite the aggregated state of the two, the perylene diimide fluorescent dye of the ortho-substituted benzoanthrone of the present invention exhibits AIE properties, and can be used in two-photon fluorescence imaging and two-photon dynamics Therapeutic aspects will have great application potential.

Description

technical field

[0001] The invention relates to the field of organic nonlinear optical materials, in particular to a perylene diimide fluorescent dye with ortho-substituted benzanthrone and its preparation and application. Background technique

[0002] Organic nonlinear optical materials have the advantages of multiple relationship between absorption wavelength and emission wavelength, fast response time, and easy processing into high-quality optical devices. They have great potential significance in information technology and industrial applications. The two-photon absorption (TPA) effect is a phenomenon in which molecules are excited by light under laser light, and it is a kind of third-order nonlinear optical effect. The molecule simultaneously absorbs two photons of the same or different frequencies, producing a very high transient photon density. Two-photon absorption has attracted great interest due to its many advantages, especially when applying this technique to ph...
