Abstract

The invention relates to a pure organic room temperature phosphorescent andfluorescent double emission polymer material capable of responding to humidity through theluminescence behavior, and belongs to the field of organic luminescent materials. The method is suitable for most phosphorescentandfluorescent hybrid systems, the phosphorescence of a phosphorescent compound is quenched by breaking hydrogen bonds in a polymer through humidity, and the change of the luminescence of the hybrid system is controlled. The humidity-responsive pure organic room temperature phosphorescent andfluorescent double emission polymer material can be obtained by copolymerizing a luminescent monomer and acrylamide. According to the method, expensive heavy metals are not used, raw materials are simple and easy to obtain, the preparation method is simple and convenient, and the obtained material has an excellent luminescent property, is water soluble and non-toxic, and can be applied to many fields.

Description

technical field [0001] The invention relates to a preparation method of a pure organic room-temperature phosphorescent fluorescent double-emission polymer capable of emitting light through humidity response, and belongs to the field of organic light-emitting materials. Background technique [0002] Room-temperature phosphorescent materials are widely used in anti-counterfeiting, biological imaging, chemical sensing, etc., and a convenient preparation method and processing process are especially needed. At present, room-temperature phosphorescent materials mainly focus on noble metal complexes, but noble metals are expensive, have limited reserves, and are potentially toxic to organisms. Therefore, it is very necessary to develop pure organic room-temperature phosphorescent materials. Traditional dual-emission materials are mostly based on fluorescent materials, and their luminescence changes are mostly based on electron transfer or energy transfer between fluorophores. Phosp...
