Abstract

The invention relates to an organic, inorganic hybrid green-light light-emitting material having a network structure, preparation and use thereof. The composition comprises an end function POSS chip structural part, an end bi-function green-light light-emitting organic group part and a closed-end organic molecule. The mol ratio is 1: n: m-2n, wherein n is equal to 1-7, and n is greater than or equal to 1 and is less than or equal to m/2. The preparation is as follows: according to the mol ratio of 1: n, using the end function POSS and the end bi-function luminous molecule under catalysis of cuprous salt by using methods, such as click chemical method, to prepare controllable organic, inorganic hybrid green-light light-emitting material having a network structure. The green-light material can be used in fields of all kinds of displays, optical communication, indoor decorative light source, three-dimensional storage, optical modulation and solar battery, and the like. The green-light material of the invention has the characteristics of easily designed and controlled structure, simple preparation process, environment-friendly property, good film-forming property, and the like.

Description

technical field [0001] The invention belongs to the field of green light emitting material and its preparation and application, in particular to an organic-inorganic hybrid green light material with a network structure and its preparation and application. Background technique [0002] The emergence of organic electroluminescent devices (Organic Light-Emitting Device, OLED) has brought a huge impact to display technology. Compared with other display technologies, OLED has significant advantages such as wide viewing angle, low energy consumption, fast response speed, ultra-thin, ultra-light, and easy molding and processing. Extensive attention and in-depth research. [0003] As one of the three primary colors, green light materials have developed rapidly in recent years. For example, Chinese patent CN1381543A discloses an energy transfer type main chain polymer light-emitting material, which realizes green light emission by controlling the content of naphthalimide derivative...
