Halo-organic heterocyclic compounds are described, in which at least two halogen atoms are bound to a nitrogen-containing heterocyclic terminal moiety of the compound, with at least one of such halogen atoms being iodine or bromine. Also described are polymethine dyes based on these heterocyclic compounds, and dendrimeric compounds and conjugates of such polymethine dyes. The polymethine dyes are characterized by enhanced properties, e.g., brightness, photostability, sensitivity and/or selective affinity that make them useful to target cancer cells, pathogenic microorganisms, and/or other biological materials, in applications such as photodynamic therapy, photodynamic antimicrobial chemotherapy (PACT), cancer treatment, selective removal or attachment of biological materials, antimicrobial coating materials, and other diagnostic, theranostic, spectrum shifting, deposition/growth, and analytic applications.
本文介绍了含有至少两个卤素原子结合在化合物的含氮杂环末端基团上的有机卤素杂环化合物,其中至少一个卤素原子是碘或溴。此外,还介绍了基于这些杂环化合物的聚甲烯染料、树状化合物和这种聚甲烯染料的共轭物。这些聚甲烯染料具有增强的性能,例如亮度、光稳定性、敏感性和/或选择性亲和力,使它们在靶向癌细胞、致病微生物和/或其他生物材料的应用中非常有用,例如光动力疗法、光动力抗菌化疗(PACT)、癌症治疗、选择性去除或附着生物材料、抗菌涂层材料以及其他诊断、治疗、光谱移动、沉积/生长和分析应用。
