We investigated the effects of exposing rhodium phthalocyanine films deposited on glass substrates by the Lagmuir-Blodgett technique to chlorine gas. The visual aspect of the films is altered upon chlorination, changing in color from blue to transparent. We performed optical absorption and Raman Scattering measurements on our films prior to and after exposing it to chlorine gas. We observed a pronounced...
The synthesis of dual-mode optical molecular switching systems based on chiral helical-shaped alkenes in which chirality can be reversely modulated by light has been recently reported. The chiroptical molecular system is based on donor-acceptor substituted inherently asymmetric thioxanthene derivatives. The switching process can be regulated by reversible protonation in the dimethylamino group. Due...
