This work provides an overview of the recent advances in the field of two-photon absorbing
chromophores active in the short-wavelength infrared (SWIR) spectral range. Herein the …

Molecular oxygen, O2, has long provided a cornerstone for studies in chemistry, physics,
and biology. Although the triplet ground state, O2 (X3Σg–), has garnered much attention, the …

The control of luminous radiation has extremely important implications for modern and future
technologies as well as in medicine. In this Review, we detail chemical structures and their …

Two photons are better than one: This principle applies to a wide range of applications,
ranging from engineering to physiology. Recent advances in our understanding of the …

In the first quarter of the twentieth century, one of the most significant events in physics and
chemistry was the establishment of the quantum theories of radiation, matter, and their …

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

We present a benchmark study of density functional approximation (DFA) performances in
predicting the two-photon-absorption strengths in π-conjugated molecules containing …

This report describes the synthetic strategies toward and optoelectronic properties of
substructures of the non-natural, planar carbon networks graphyne and graphdiyne, which …

All-optical switching applications require materials with large third-order nonlinearities and
low nonlinear optical losses. We present a design approach that involves enhancing the real …

Organic upconversion is a unique process in which low-energy light (usually NIR light) is
converted to high-energy light through either the two-photon absorption (TPA) mechanism or …
