Synthesis of Pentacyclic 13-Azadibenzo[a,de]anthracenes via Anionic Cascade Ring Closure

open access: yes, 2016
Bromine−lithium exchange using tert-butyllithium at −78 °C initiates a cascade process whereby either xanthone derivatives or pentacyclic 13-azadibenzo[a,de]anthracenes are produced in high yields.

Hydroxylated-Benz[a]anthracenes Induce Two Apoptosis-Related Gene Expressions in the Liver of the Nibbler Fish Girella punctata

open access: yesToxics
Polycyclic aromatic hydrocarbons (PAHs) are known to have toxic effects on fish. In this study, we examined the effects of benz[a]anthracene (BaA), a type of PAH, on fish liver metabolism.

STUDIES OF THE PREPARATION OF PI-EXTENDED ANTHRACENES AND THEIR REACTIVITY WITH AN EMPHASIS ON THEIR PHOTOREACTIVITY [PDF]

open access: yes, 2015
Both 9,10-diaryl and 9,10-diarylethenyl substituted Anthracenes have recently been forwarded as light-regulated semiconducting materials, as well as potential constituent molecules in light-harvesting devices for the organic solar cell applications.

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

Non‐Electronic Activation of Anthracenes Using Steric Repulsion of the 9‐Substituent with Chloro Groups at the peri‐Positions

open access: yes
We investigated how the introduction of substituent at the 9- or 10-position of the 1,8-dichloroanthracene framework affects the horizontal and vertical distortions of the anthracene rings.

Helical Folding of Abiotic Chiral Poly(phosphodiester)s

open access: yesChemistry – A European Journal, EarlyView.
Design and structural analysis of a new class of phosphodiester foldamers are presented. These oligomers that fold into single helical architecture showed length and temperature stability dependence comparable to DNA duplexes. ABSTRACT Functions of biomolecules are intimately linked to their structures which result from the folding of a linear sequence
