Organic dye for a dye-sensitized solar cell (DSSC) comprising at least one electron-acceptor unit and at least one -conjugated unit. Said organic dye is particularly useful in a dye-sensitized photoelectric transformation element which, in its turn, can be used in a dye-sensitized solar cell (DSSC).

Provided are dyes and compositions which are useful in a number of applications, such as the detection and monitoring protein aggregation, kinetic studies of protein aggregation, neurofibrillary plaques analysis, evaluation of protein formulation stability, and analysis of molecular chaperone activity.

Provided are dyes and compositions which are useful in a number of applications, such as the detection and monitoring protein aggregation, kinetic studies of protein aggregation, neurofibrillary plaques analysis, evaluation of protein formulation stability, protein thermal stability shift assay and analysis of molecular chaperone activity. These dyes and compositions are also useful as probes in nucleic acid and protein detection.
