ABSTRACT:
A photoactive moiety exhibiting an anisotropic transition dipole. The moiety exhibits emission of polarized light in response to energy absorption. In a preferred embodiment, the moiety comprises a particle from the group consisting of a crystalline arrangement of photoactive molecules and a photoactive nanocrystal. The moiety may include a matrix in which photoactive objects exhibiting an anisotropic emission dipole are embedded. The moiety may be photobleached to product the anisotropy and the photoactive objects may have a one dimensional transition dipole in their natural state.
