Dyes having coumarin core which absorbs and emits in deep-red to NIR region have
become incredibly valuable due to their essential role in biology, DSSC, NLO materials, and …

Because of long‐range order and high chemical purity, organic crystals have exhibit unique
properties and attracted a lot of interest for application in solid‐state lasers. As optical gain …

Recently, a lot of interest has been centred on the optical properties of hexagonal boron
nitride (h‐BN), which has a similar lattice structure to graphene. Interestingly, h‐BN has a …

In the present work, the title chalcone,(2E)-3-(4-fluorophenyl)-1-(4-{[(1E)-(4-fluorophenyl)
methylene] amino} phenyl) prop-2-en-1-one (abbreviated as FAMFC), was synthesized and …

Synergistic combination of organic and inorganic nature in van der Waals metal-organic
frameworks supports different types of robust excitons that can be effectively and …

Asymmetric diradical molecular systems with different resonance mechanisms are largely
unexplored. Herein, two conjugated asymmetric diradicals with Blatter and phenoxyl …

The ability to form triplet excited states upon two-photon excitation is important for several
applications of metalloporphyrins, including two-photon phosphorescence lifetime …

We investigate the accuracy of different formalisms within density functional theory in
prediction of two-photon absorption (2PA) spectra for substituted oligophenylvinylenes …

The synthesis of borondifluoride complexes of curcuminoids and one-and two-photon
absorption properties of 1 and 2 are described. These compounds allow the preparation of …

The electronic relaxation dynamics of the second singlet excited states of several cyanine
dyes was studied through the femtosecond fluorescence up-conversion technique. Our …
