"modular molecular units connected anthracene hydrocarbon bridges... shining with light electrons on opposite ends of structure connect to each other aligning spin states... after bridge removed electrons stayed connected through aligned spinsattached bright light-emitting radical to anthracene molecule... excitation spreads out neighboring anthracene, causing 3 electrons spinning same way, further radical group attached to other side its electron also coupled... room temperature... quantum computers, LEDs"
