Spiro-TTB , 2,2',7,7'-tetra(N, N-di-tolyl)aMino-spiro-bifluor 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.
