Description and Uses

Tetraphenylmethane (TPM) is an organic alkane compound formed by replacing the hydrogen atoms of methane with benzene rings. TPM is an important optoelectronic material, primarily used in the preparation of OLED materials and light-emitting devices. Bipolar tetraphenylmethane derivatives prepared with TPM as the core structure carry both hole-transfer and electron-transfer units, significantly enhancing the molecule's vitrification ability and improving its luminescence performance^[2].

Tetraphenylmethane is used to prepare a tetrapyridone tecton, which forms a diamondoid network with large internal chambers. It is also used in the preparation of 1-{4-[tris-(4-acetyl-phenyl)-methyl]-phenyl}-ethanone by Friedel-Crafts acylation reaction with acetyl chloride using aluminum chloride as catalyst.
