Spiro-TTB Usage And Synthesis

Description

Spiro-TTB has a spirofluorene core with four attached ditolylamine at the 2 and 7 positions of spirofluorene. Like Spiro-OMeTAD, it is electron-rich and commonly used as a hole-transport layer material in OLED, OPV, and perovskite solar cells.

Uses

Spiro-TTB shows high fluorescence efficiency and luminous brightness, making it a very effective fluorescent material.

Advantages

Spiro-TTB has a very high charge carrier mobility, high fluorescence efficiency and luminous brightness, good thermal stability, a wide photoelectric band gap.
