The invention relates to fluorescent dyes that are substituted or unsubstituted derivatives of 1-(isoindolyl)methylene-isoindole that are bound through both isoindole nitrogens to a boron difluoride moiety, forming a fluorescent dibenzopyrrometheneboron difluoride compound ##STR1## that is further substituted by bathochromic substituents that are aryl or heteroaryl moieties further substituted by an additional aryl or heteroaryl, that is itself optionally further substituted by an additional aryl or heteroaryl. These aryl and heteroaryl groups are separated by a covalent bond, or by an ethenyl, butadienyl or hexatrienyl linkage. The dyes of the invention are particularly useful as labels for carriers, particularly polymeric microparticles. The resulting microparticles have a long-wavelength fluorescence emission, and possess utility for tracing flow in biological systems, particularly in tracing blood flow.
本发明涉及荧光染料,其为1-(异吲哚基)亚甲基-异吲哚的取代或未取代衍生物,通过两个异吲哚的氮原子与硼二氟基团结合,形成荧光二苯并吡咯甲烷硼二氟化合物##STR1##,进一步取代了巴托克罗米亚基团,该基团是芳基或杂环芳基团,进一步取代了另一个芳基或杂环芳基团,该芳基或杂环芳基团本身可以选择进一步取代另一个芳基或杂环芳基团。这些芳基和杂环芳基团由共价键或乙烯基、丁二烯基或己三烯基连接。本发明的染料特别适用于作为载体的标记,特别是聚合物微粒。所得到的微粒具有长波长荧光发射,并具有在生物系统中追踪流动的实用性,特别是追踪血流。
