The goal is to search for more efficient as well as more practical nonlinear optical (NLO) chromophores. Two series of three-dimensional NLO chromophores with five substituted branches and curved conjugated frameworks as the central coupling unit wer

Electronic spectra, and the nonlinear optical (NLO) properties of five isomers of C96 were investigated using density functional theory and semi-empirical methods. The simulated electronic spectra of C2:181, C1:144, C1:145, and C2:176 have strong abs

The absorption and emission spectra of a series of oxyluciferin derivatives with different substituents, as well as 6'-amino oxyluciferins in different enol and keto forms, with or without an active-site model of luciferase, were systematically inves

The absorption and emission spectra of six different possible light emitters of coelenteramide: neutral, phenolate anion, phenolate anion with a counter ion (phenolate−–M+), amide anion, pyrazine anion, and the dianion were investigated with the

The contributions of explicit water molecules to color-tuning mechanism of firefly were studied. The explicit water molecules cause two different structures in the geometrical parameters of keto(-1) both in vacuo and aqueous solution. There are somew

Firefly bioluminescence has attracted great attention for many years. Some details of the mechanism underlying firefly bioluminescence remain elusive. In this study the formation and decomposition reactions of firefly dioxetanone (DO) have been inves

Highly ordered microporous films of silver-containing regular arrays of spherical pores of differing diameters were prepared by electrochemical deposition into the interstitial spaces of a template formed by nanosphere lithography. These nanostructur

In order to find a relationship between firefly luciferases structure and bioluminescence spectra, we focus on excited substrate geometries which may be affected by rigid luciferases. Density functional theory (DFT) and time dependent DFT (TDDFT) wer

Polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS) has been applied to determine the conformation, orientation, and hydration of a monolayer of 2,3-di-O-phytanyl-sn-glycerol-1-tetraethylene glycol-dl-alpha-lipoic acid este

Ring strain energies (RSEs) of heterocyclic compounds are predicted compared to their analogous homocyclic compounds using the G3 method. Suitable reference compounds are devised for row 2 and row 3 heterobicyclic alkenes. Any difference in energy be
