Circular polarization of photochemiluminescence from the photoisomer of a conformationally fixed 2,11-diaza[3.3](9,10)anthracenoparacyclophane derivative‡
Abstract
The conformation of 2,11-diaza[3.3](9,10)anthracenoparacyclophane 1, which underwent photointerconversion with isomer 2, was fixed with the aid of a chiral camphanic auxiliary to have molecular chirality, and the photochemiluminescence from the modified 2a was circularly polarized reflecting the chirality of the emitting state.
