The present application discloses novel lanthanide chelate designs (Formula (I) and Formula (III)) having fluorenyl-, fluorenylethynyl, 9H-carbazolyl-, 9H-carbozolylethynyl-, dibenzothiophenyl-, dibenzothiophenylethynyl-, dibenzofuranyl or dibenzofuranylethynyl pyridine chromophores around an emitting lanthanide ion, e.g. an europium(III) ion. The three-membered ring chromophores exhibit high molar absorptivity and luminescence with lanthanide ions. The application also discloses a detectable molecule comprising a biospecific binding reactant useful in bioaffinity based binding assay, luminescent lanthanide chelating ligands, as well as a solid support conjugated with the chelates.
本申请公开了新型镧系元素螯合物设计(式(I)和式(III)),其芴基、芴乙炔基、9H-咔唑基、9H-咔唑乙炔基、二苯并噻吩基、二苯并噻吩乙炔基、二苯并呋喃基或二苯并呋喃乙炔基吡啶发色团围绕着发射镧系元素离子,例如铕(III)离子。三元环发色团对镧系离子具有很高的摩尔吸收率和发光性能。该申请还公开了一种可检测的分子,包括一种用于基于生物亲和力的结合测定的生物特异性结合反应物、发光镧系元素螯合配体以及与螯合剂共轭的固体支持物。
