  • Patent number: 11578265
    Abstract: The present subject matter is directed to a luminogen exhibiting aggregation induced emission, wherein T1, T2, and T3 comprise one or more polyynes as a conjugated bridge. The present subject matter is also directed to an AIEgen comprising a hydrophilic pyridium group as a strong electron-withdrawing group; a piperazine group as an electron-donating group; and a ?-Cyanostilbene; wherein the AIEgen exhibits aggregation induced emission. The present subject matter is directed to a method of synthesizing an AIEgen and is further directed to a method of labeling comprising incubating a subject having cells with a conjugate formed by conjugating an AIEgen with an antibody; and selectively labeling desired cells by turn-on imaging, wherein labeling occurs when the desired cells are selectively stained by fluorescent emission of the AIEgen upon degradation of the antibody after cellular internalization of the conjugate through endocytosis.
