Abstract

The invention discloses a water-soluble two-photon polymerization initiator as well as assembling method and use thereof, the water-soluble two-photon polymerization initiator is assembled by host molecule 2-hydroxypropyl beta-cyclodextrin and guest molecule 2,7-di(4-pentoxy styrene)-anthraquinone, the molecular formula of the 2,7-di(4-pentoxy styrene)-anthraquinone is described by a formula I as shown in the specification. The water-soluble two-photon polymerization initiator is capable of initiating two-photon polymerization to process three-dimensional hydrogel in a water phase, the laser processing energy is lower in comparison with the processing energy (20-60mW) in the prior art, and the disadvantage of the residue of the organic solvent in the prior art is overcome.

Description

technical field [0001] The invention belongs to the technical field of two-photon micromachining, and relates to a water-soluble two-photon polymerization initiator, an assembly method and application. Background technique [0002] Two-photon absorption refers to the process of a molecule absorbing two photons at the same time under the action of strong laser light, which is a phenomenon of the interaction between light and matter under the action of strong laser light. The process of photopolymerization initiated by two-photon absorption is called two-photon polymerization. Two-photon polymerization microfabrication is an important application of two-photon polymerization. Two-photon polymerization microfabrication can be used to process some nanoscale microstructures to be used as tissue engineering scaffolds. The microstructure processed by two-photon polymerization has higher resolution and can break through the diffraction limit, making the processed microstructure mor...
