New dendrimers and longer half-life (IMAGE) Kyushu University Caption Second-generation dendrimers with tert-butyl (left) and methoxy groups (right) applied to light-emitting electrochemical cells (LEC). The lifetime of LEC devices using dendrimers with hydrophilic methoxy groups (right) is more than 10 times longer than that of hydrophobic dendrimers.
