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 …

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 …

The last few years have seen a steady increase in small molecule based conjugated
materials, which promise innovative (opto) electronic applications. This requires however a …

In recent years considerable efforts have been put forth in two-photon initiated
polymerization (TPP)-based two-and three-dimensional (2D and 3D) nano/microfabrication …

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 interest …

Recent innovations in the area of micro-and nanofabrication have created a unique
opportunity for patterning surfaces with features with lateral dimensions spanning over the …

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 …

Though investigated for decades, interest in push− pull chromophores (D− π− A), strong
electron donors (D) connected by π-conjugating spacers to strong electron acceptors (A) …

The vertical and adiabatic ionization potential (IPV and IPA) and vertical electron affinity
(EAV) for six explosives, hexogen (RDX), octogen (HMX), triacetone triperoxide (TATP) …

Most symmetric quadrupolar molecules designed for two-photon absorption behave as
dipolar molecules in the S1 electronic excited state. This is usually explained by a breakup …
