  Preparation, Structure, and Amphoteric Redox Properties of p-Phenylenediamine-Type Dyes Fused with a Chalcogenadiazole Unit

  摘要：

  4,7-Bis(dialkylamino)benzo[c] [1,2,5]chalcogenadiazoles are a novel class of organic dyes that undergo reversible two-stage one-electron oxidation as well as one-electron reduction. They exhibit absorption maxima in the long-wavelength region, which are assigned as intramolecular charge transfer bands from the phenylenediamine moiety to the electron-accepting heterocycle. Their redox properties as well as molecular and crystal structures are affected by the alkyl substituents on the amino nitrogen and/or by the chalcogen atom (O, S, Se) in the heterocycle.

  derivatives of 5-oximinobenzo-2,1,3-oxadiazole-4-one is reported and their rearrangement to 4,7-dioximino derivatives of benzo-2,1,3-oxadiazole, 2-phenylbenzotriazole and benzotriazole described. Geometric isomerism related to oximino group was investigated. NMR spectra of 4,7-dioximes show the existence in solution of three geometrical isomers, whose configuration was assigned. The derivatives of 5-oximinobenzo-2

  据报道，制备了5-氧亚氨基苯并-2,1,3-恶二唑-4-one的某些衍生物，并将其重排为苯并-2,1,3-恶二唑，2-苯基苯并三唑和苯并三唑的4,7-二氧亚氨基衍生物。 。研究了与肟基相关的几何异构现象。4,7-二恶英的NMR光谱表明，存在三种几何异构体，并已对其构型进行分配。在此研究的5-氧亚氨基苯并-2,1,3-氧二唑-4-one的衍生物似乎仅以一种形式存在。

  Water soluble polymeric dyes and polymeric tandem dyes are provided. The polymeric dyes include a water solvated light harvesting multichromophore having a conjugated segment of aryl or heteroaryl co-monomers including branched non-ionic water soluble groups (WSG) comprising two or more water soluble polymers. In some cases, the branched non-ionic water soluble groups (WSG) of the present disclosure are capable of imparting solubility in water in excess of 50 mg/mL to the multichromophore. The polymeric tandem dyes further include a signaling chromophore covalently linked to the multichromophore in energy-receiving proximity therewith. Also provided are aggregation-resistant labelled specific binding members that include the subject water soluble polymeric dyes. Methods of evaluating a sample for the presence of a target analyte and methods of labelling a target molecule in which the subject polymeric dyes find use are also provided. Systems and kits for practicing the subject methods are also provided.

  Polymeric tandem dyes are provided. The polymeric tandem dyes include a narrow emission fluorophore configured as a pendant acceptor in energy-receiving proximity to a donor water solvated light harvesting multichromophore. The narrow emission acceptor fluorophores of the present disclosure are capable of providing polymeric tandem dyes having a variety of narrow emission spectrums suitable for multiplexing. Also provided are compositions for multicolor fluorescent signal generation that include two or more polymeric tandem dyes. Methods of evaluating a sample for the presence of a target analyte and methods of labelling a target molecule in which the subject polymeric dyes find use are also provided. Systems and kits for practicing the subject methods are also provided.
