The linear and nonlinear optical properties of a series of linear and cross-conjugated platinum(II) acetylide complexes that contain extended p-(phenylene vinylene) chromophores are reported. The complexes exhibit very high femtosecond two-photon absorption (2PA) cross section values (σ2 up to 10 000 GM), as measured by nonlinear transmission (NLT) and two-photon excited fluorescence (2PEF) methods. The large 2PA cross sections span a broad range of wavelengths, 570-810 nm, and they overlap with the triplet excited state absorption. Spectral coincidence of high cross section 2PA and triplet absorption is a key feature giving rise to efficient dual-mode optical power limiting (OPL).

A family of one- and two-photon dyes that have overlapping fluorescence excitation maxima between 365 nm and 425 nm and that are specifically functionalized for coupling to biomolecules. The dyes have defined Stokes shifts such that they produce a continuum of emission wavelengths. The dyes are asymmetrical bis stilbenes. The asymmetry of these dyes facilitates functionalization of the dyes with carboxyl, thiol, aldehyde-reactive or amine-reactive groups, which in turn facilitates coupling with macromolecules. Furthermore, the dyes of the present invention are photostable and have high quantum yields (fluorescence intensity).
