Abstract

The invention provides a photochromic diarylethene compound with upconversion luminescence performance and application thereof. The photochromic diarylene compound has the structure shown in formula I. The photochromic diarylethene compound of the present invention is a type of switch-type single-photon absorption up-conversion luminescent material, which can realize up-conversion luminescence with high vibration energy level absorption, and can realize up-conversion luminescence through multiple wavelength light regulation Due to the strong tissue penetration ability of long wavelength, the photochromic diarylethene compound can also effectively eliminate background noise such as autofluorescence, which is expected to be applied in super-resolution single-photon imaging systems.

Description

technical field

[0001] The invention belongs to the field of luminescent materials, and in particular relates to a photochromic diarylethene compound with up-conversion luminescence performance and an application thereof. Background technique

[0002] Up-conversion luminescent materials can convert low-energy long-wavelength light into high-energy short-wavelength light. The methods that can achieve photon upconversion generally include two-photon absorption upconversion, rare earth material upconversion, and triplet-triplet annihilation upconversion developed in recent years. In addition, there is another way of upconversion, single photon upconversion. Absorption upconversion (phonon-assisted upconversion), although this type of material is relatively less studied. However, single-photon absorption upconversion has multiple advantages: firstly, no oxygen removal is required, secondly, low light intensity is required, thirdly, high upconversion efficiency and single-photon...
