Light harvesting luminescent multichromophores that are configured upon excitation to transfer energy to, and amplify the emission from, an acceptor signaling chromophore in energy-receiving proximity therewith are provided. Also provided are compositions for labelling a target. The labelling composition may include a donor light harvesting multichromophore and an acceptor signaling chromophore in energy-receiving proximity to the donor light harvesting multichromophore. Also provided is an aqueous composition for labelling a target, including: a donor light harvesting multichromophore; an acceptor signaling chromophore in energy-receiving proximity therewith; and a sensor biomolecule. Methods for using the subject compositions are also provided.

A laundry care composition including: (a) at least one laundry care ingredient and (b) a leuco composition. The laundry care composition has a HA of at least 10 and produces a relative hue angle on fabric outside the range of 210 to 345. Methods of treating textiles with such laundry care compositions.

A leuco polymer of the formula:

##STR00001##

Each of the G radicals is independently selected from the group consisting of:

##STR00002##

A is an arylene or heteroarylene, A.sup.1 is an aryl or heteroaryl, and B is a bridge member. R.sup.1 and R.sup.2 are independently selected from the group consisting of hydrogen and R.sup.4. R.sup.4 is independently selected from the group consisting of alkyl, cycloalkyl, aryl, alkoxy, amino, substituted alkyl, substituted cycloalkyl, substituted aryl, substituted alkoxy and substituted amino. X.sup.i is a charge balancing mono- or multi-valent counterion and i is an integer from 1 to 10. Methods of making the leuco polymer, laundry care compositions comprising the leuco polymer and methods of treating textiles with such laundry care compositions.
