Effect of substituents on the fluorescence quenching of a few (anthracen-9-yl)methanamines

This article deals with the photophysical properties of a few (anthracen-9-yl)methanamines. Analysis of absorption and the fluorescence emission spectra of these compounds indicated intramolecular photoinduced electron transfer leading to quenching of excited states, the efficiency of which depends on the geometrical constraints and electronic factors pertaining to the molecule. The decay kinetics studied using Time Correlated Single Photon Counting showed a bi-exponential decay indicating the involvement of two transient species in the excited state of these molecules. Also, we build up a relation between the rate of the photochemical reaction, free energy change and quenching of excited states.

An easy synthesis of lepidopterene from 9-chloromethyl anthracene. Evidence for a free radical mechanism

This communication reports a novel and efficient synthesis of lepidopterene from 9-(chloromethyl)anthracene. Furthermore, the radical nature of the process is unambiguously established through the obtention of several 9-anthracenemethyl derivatives, which are formed via a common 9-anthracenemethyl radical intermediate, derived from 9-(iodomethyl)anthracene.
