Description

A significant long-lived phosphorescent color change with temperature increase using efficient inter-molecular thermally activated energy transfer was observed. The materials are a host-guest compound composed of secondary amino substituted aromatic carbons as a guest, phosphorescent iridium complex as a guest, and amorphous steroid compound as a host matrix. The phosphorescent color was gradually changed with increasing temperature from red in low temperature region at 77 K to green in room temperature region at 300 K. The red color was originated from aromatic carbons and the green color was originated from iridium complex, resulting from thermally activated energy transfer with temperature increase.
