A blue electroluminescent material based on a binaphtyl compound of the general formula (I). Particular embodiments having the general formula have good solubilities in common organic solvents, resist crystallization and can be sublimed in a device fabrication process. These properties enable the fabrication of organic electroluminescent devices.

Binaphthol based chromophores for the fabrication of blue organic light emitting diodes

Chromophores having two-photon or other multi-photon absorptivity. The chromophores are based on a structure of four stilbenoid groups attached to a paracyclophane core, where each stilbenoid group comprises a nitrogen-containing organic group attached by its nitrogen atom to a stilbenoid arm. In particular embodiments, at least one of the stilbenoid groups includes a sulfonium, ammonium, selenium, iodonium or phosphonium moiety. The chromophores have utility as photo-polymerization initiators and two-photon fluorophores for biological imaging.

Paracyclophane molecules for two-photon absorption applications

Two-photon or multi-photon chromophores having a conjugated pi-electron system with donating groups at each end of the pi-electron system providing charge-transfer properties, and having quaternary amine groups that can enhance the solubility of the chromophore in water. In a particular embodiment, the chromophore is based on a distyrylbenzene core, with donor or acceptor groups attached to the central benzene ring.
