Tetraphenylethylene Derivatives Used for the Development of Reticular Frameworks and Aggregation-Induced Emission-Active Materials

Tetra(4-pyridylphenyl)ethylene (= TPTPE), a tetraphenylethylene derivative bearing four pyridyl groups, has been used in the synthesis of metal–organic frameworks (MOFs)¹⁾ and cage-shaped coordination complexes.²⁾ These MOFs and coordination complexes have attracted attention due to their emission and adsorption-induced quenching behaviors. Tetrakis(4-aminophenyl)ethylene (= ETTA), a tetraphenylethylene derivative with four amino groups, is used in the synthesis of covalent organic frameworks (COFs). COFs with “kagome" topology containing both hexagonal and triangular pores have been synthesized by exploiting D_2h-symmetric molecular structure of ETTA.³⁾ Highly crystalline COFs have also been reported by taking advantage of ETTA’s propeller-like conformation.⁴⁾ Furthermore, tetraphenylethylene derivatives are key building blocks for the development of materials exhibiting aggregation-induced emission (AIE), and both TPTPE and ETTA have been applied in the development of sensors and bioimaging materials.^5,6)
