title: A three-dimensional assembly of pyrene dye on a tetraphenylethane scaffold enhances fluorescence quantum yield.
abstract: A three-dimensional pyrene assembly on a tetraphenylethane skeleton enhanced the fluorescence quantum yield compared to the yield obtained when using monomeric species, without changing the shape of the emission spectrum. The unique spacing of the pyrene units may prevent intramolecular fluorescence quenching or non-radiative decay.
