A combined theoretical and experimental investigation on the influence of the bromine substitution pattern on the photophysics of conjugated organic chromophores

23-Jan-2018 | B. Mettra; Y. Y. Liao; T. Gallavardin; C. Armagnat; D. Pitrat; P. Baldeck; T. Le Bahers; C. Monnereau; C. Andraud, Physical Chemistry Chemical Physics, 2018

A large series of structurally related two-photon photosensitizers with heavy atom substitution were synthesized and evaluated through a combined spectroscopic (steady-state and time resolved), photophysical and computational study. Our aim was to identify some relevant parameters related to ...

Mono-, di- and tetrarhenium Fischer carbene complexes with thienothiophene substituents

19-Jan-2018 | Zandria Lamprecht; Shankara G. Radhakrishnan; Alexander Hildebrandt; Heinrich Lang; David C. Liles; Nora-ann Weststr ..., Dalton Transactions, 2018

The oxidative cleaving of a rhenium–rhenium bond by bromine in binuclear Fischer carbene complexes proves to be an effective method to prepare mononuclear bromido-carbene complexes. The reaction of mono- and dilithiated thieno[2,3-b]thiophene (2,3-b-TTH2) and thieno[3,2-b]thiophene (3,2-b-TTH2) ...

Highly flame retardant and bio‐based rigid polyurethane foams derived from orange peel oil

18-Jan-2018 | C. Zhang, Sanket Bhoyate, M. Ionescu, P. K. Kahol, Ram K. Gupta, Polymer Engineering and Science, 2018

Limonene dimercaptan (LDM), an orange peel oil‐based derivative, and glycerol‐1‐allyl ether (GAE) were used to synthesize bio‐based polyol (LDM‐GAE) using one step photochemical thiol‐ene reaction. The synthesized polyol was used to prepare flame retardant polyurethane foams using dimethyl ...

SOMO–HOMO Level Inversion in Biologically Important Radicals

21-Dec-2017 | Anil Kumar; Michael D. Sevilla, Journal of Physical Chemistry B, 2017

Conventionally, the singly occupied molecular orbital (SOMO) of a radical species is considered to be the highest occupied molecular orbital (HOMO), but this is not the case always. In this study, we considered a number of radicals from smallest diatomic anion radicals such as superoxide anion ...

Two-Dimensional Polymer Synthesized via Solid-State Polymerization for High-Performance Supercapacitors

21-Dec-2017 | Wei Liu; Mani Ulaganathan; Ibrahim Abdelwahab; Xin Luo; Zhongxin Chen; Sherman Jun Rong Tan; Xiaowei Wang; Yanpeng L ..., ACS Nano, 2017

Two-dimensional (2-D) polymer has properties that are attractive for energy storage applications because of its combination of heteroatoms, porosities and layered structure, which provides redox chemistry and ion diffusion routes through the 2-D planes and 1-D channels. Here, conjugated aromatic ...

Concerns for ozone recovery

08-Dec-2017 | Qing Liang; Susan E. Strahan; Eric L. Fleming, Science , 2017

Reactive halogen gases containing chlorine (Cl) or bromine (Br) can destroy stratospheric ozone via catalytic cycles. The main sources of atmospheric reactive halogen are the long-lived synthetic chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), carbon tetrachloride (CCl4), methyl ...
