The range of organic compounds whose degenerate two-photon absorption (2PA) spectrum
has been reported has increased rapidly in recent years, in parallel with the growing …

Strategies for the optimization of molecular second‐order nonlinearities have emerged over
the past few years, but significant questions still remain. This review highlights recent …

Molecules with weak ground-state absorption that form strongly absorbing excited states can
be used in optical limiters, which can protect sensors or human eyes from optical damage. …

Two-photon absorption, the process by which an excited molecule or material is produced
by the simultaneousabsorption of two photons, has been studied extensively in recent years, …

Two-photon excitation provides a means of activating chemical or physical processes with
high spatial resolution in three dimensions and has made possible the development of three-…

A strategy for the design of molecules with large two-photon absorption cross sections, δ,
was developed, on the basis of the concept that symmetric charge transfer, from the ends of a …

Systems that use light as a carrier of information offer the possibility of extremely high speed
processing, transmission, and storage of data. Many such photonic systems require high-…

The two-photon absorption properties of a series of bis dialkylamino- or diarylamino-substituted
diphenylpolyenes and bis(styryl)benzenes have been investigated. Two-photon …

Large two-photon absorptivities are reported for symmetrical bis-donor stilbene derivatives
with dialkylamino or diphenylamino groups. These molecules exhibit strong optical limiting of …

The dielectric permittivity and electric breakdown strength of nanocomposites comprising
poly(vinylidene fluoride-co-hexafluoro propylene) and phosphonic acid surface-modified …
