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.

A dye-doped laser protective film is disclosed, comprising a polymer layer A and a polymer layer B. The polymer molecules in the polymer layer A are arranged in a left-handed helical structure which can reflect a left-handed polarized laser. The polymer molecules in the polymer layer B are arranged in a right-handed helical structure which can reflect a right-handed polarized laser. The combination of the polymer layer having the left-handed helical structure and the polymer layer having the right-handed helical structure can completely reflect circularly polarized light. In addition, the dye can absorb incident laser, so as to expand the protection angle of the laser protective film. The dye-doped laser protective film of the present disclosure has a simple manufacturing process, large protection angle and good flexibility, and can refit existing devices. Thus, the dye-doped laser protective film of the present disclosure has a good application prospect in many fields such as laser goggles, window films and the like.
