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 …

Optically active molecular materials, such as organic conjugated polymers and biological
systems, are characterized by strong coupling between electronic and vibrational degrees of …

Time-dependent density-functional theory (TDDFT) describes the quantum dynamics of
interacting electronic many-body systems formally exactly and in a practical and efficient …

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 …

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 …

Functional organic materials with enhanced two‐photon absorption lead to new
technologies in the fields of chemistry, biology, and photonics. In this article we review …

Strategies for the design and construction of non-linear, 2D and 3D conjugated
macromolecules are presented in this critical review. The materials, termed here as star …

We present a joint theoretical and experimental work aimed to understand the spectroscopic
behavior of multipolar dyes of interest for nonlinear optics (NLO) applications. In particular …

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 …

π-Helical push–pull dyes were prepared and their (chir) optical properties were investigated
both experimentally and computationally. Specific fluorescent behaviour of bis-substituted …
