Single-component dual emission and full-spectrum color tuning from through-space charge transfer in asymmetric [2.2]paracyclophanes
Organic fluorophores are typically limited to a single emission color, because rapid relaxation funnels the excited population to one minimum before it emits. We report asymmetric pseudo-para [2.2]paracyclophanes that break this limit by placing a diphenylaniline donor and a triazine or cyano acceptor on opposite rings...
