A method of identifying a first object, the method comprises: providing a first object comprising a material, the material comprising a polymer and a luminescent compound; and detecting an absorption and/or excitation and/or emission spectrum from the luminescent compound of the first object which is indicative of the identity of the object; wherein the luminescent compound is represented by the following general formula (A): wherein X represents one of a nitrogen atom, an oxygen atom, a sulphur atom, a phosphorus atom, or a selenium atom; R represents an aromatic group and/or an aliphatic group; p is an integer of 1 to 2; q and s are independently integers of 1, 2, 3, or 4; Y1, Y2, and Y3 independently represent a hydrogen atom, a deuterium atom, a fluorine atom, a chlorine atom, a bromine atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a polyglycol group (e.g. a group comprising a polyethylene glycol moiety), an oxygen atom (e.g. a hydroxyl group or an alkylated oxygen atom forming an alkoxy group), a nitrogen atom (e.g. a primary, secondary, or tertiary amine group), a cyano group, a nitro group; and/or wherein Y1, Y2, and/or Y3 may combine together to form a condensed ring (e.g. a condensed aromatic ring).
一种识别第一对象的方法,该方法包括:提供一种第一对象,该对象包含一种材料,该材料包含聚合物和发光化合物;以及检测来自第一对象发光化合物的吸收和/或激发和/或发射光谱,该光谱表明对象的身份;其中发光化合物由以下通式(A)表示:其中X代表氮原子、氧原子、硫原子、磷原子或硒原子中的一个;R代表芳香族和/或脂肪族基团;p是1到2的整数;q和s是独立的1、2、3或4的整数;Y1、Y2和Y3独立代表氢原子、氘原子、氟原子、氯原子、溴原子、取代或未取代的烷基团、取代或未取代的芳基团、聚乙二醇团(例如,包含聚乙二醇部分的团)、氧原子(例如,羟基或形成醇氧基的烷基化氧原子)、氮原子(例如,伯胺、仲胺或叔胺基团)、腈基、硝基;和/或其中Y1、Y2和/或Y3可以相互结合形成一个稠环(例如,稠合的芳香环)。
