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.

Solvent-dependent diverse reactivity of (anthracen-9-yl)methyl sulfides with a few electron-deficient acetylenes is described. Diversity in reactivity is attributed to competition between one electron transfer, two electron transfer and Diels-Alder reaction of these sulfides with electron-deficient acetylenes. We have proposed plausible mechanisms to account for various reactions observed by us.

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.

Pyrolyses of a series of selenides and diselenides were studied. Selenides and diselenides bound with an active methylene group like benzyl gave a variety of substituted bibenzyls and related ethane derivatives in high yields. Other diselenides were easily caused to cleave to give various aromatic and aliphatic olefins in good yields together with elemental selenium. Lepidopterene, paracyclophane, and benzocyclobutene were prepared by thermal cleavage of their corresponding phenylselenomethyl-substituted compounds as an application of the pyrolysis concerned.
