Abstract

The invention relates to a fluorescent sensor array based on conjugated polymers and application thereof. Three different synthetic routes are employed for synthesis of four aromatic hydrocarbons with halogens at two ends and two aromatic hydrocarbons with alkynyls at two ends; and different monomers are combined through Sonogashira coupling for synthesis of seven conjugated polymers which constitute the fluorescent sensor array applied to mode identification of nine metal ions. The array has similar response on same-group elements in the element periodic table and has relatively large response difference on different-group elements, so that the ions in different groups can be easily distinguished; and also, the array has slightly different response on the same kinds of ions which are in one same group but in different periods, so that the same-group different-period ions can be subjected to preliminary detection. During practical application, the response mode of a to-be determined standard substance can be stored, and the components of a to-be analyzed substance can be determined by determining the matching degree between the response mode of the to-be analyzed substance and the standard mode.

Description

technical field [0001] The invention relates to a fluorescent conjugated polymer sensing material, in particular to a fluorescent sensor array based on a conjugated polymer, which is used for pattern recognition of metal ions. Background technique [0002] Compared with other traditional materials, conjugated polymer fluorescent sensing materials have obvious advantages, which are mainly characterized by signal amplification based on molecular wire effect and adjustable structure (see literature: Chem. Rev. 2007, 107, 1339 -1386). The design of conventional fluorescent-conjugated polymer sensors usually follows a “lock and key” pattern (one sensor for one analyte). Although there are many successful examples of using this method, this method also has some shortcomings, such as the need to spend a lot of effort to design and synthesize sensing molecules with specific selectivity for a specific analyte. Recently, the design strategy of combining a series of sensing elements...
