    摘要: A reconfigurable polar molecule includes a symmetric nonpolar molecule portion having an elongated shape defined by a longitudinal axis and lateral axis, the longitudinal axis being longer than the lateral axis; a positive ionically charged group at a first end and a negative ionically charged group at a second end of the longitudinal axis, the positive and negative ionically charged groups forming a permanent dipole; a first bridging group and a second bridging group on opposing ends of the lateral axis, the first and second bridging groups being linear nonpolar groups; and a first support portion bonded to the first bridging group, and a second support portion bonded to the second bridging group, the first bridging group and the second bridging group being nonpolar and having structures that enable free rotation of the symmetric nonpolar molecule portion through the first bridging group and the second bridging group.

    摘要: Bis(p-alkylphenylethynyl)anthracenes are described for use as fluorescer components in chemiluminescent reaction mixtures and in precursor solutions or solid mixtures. Chemiluminescent mixtures comprising these fluorescers are shown to generate higher light capacity and higher quantum yields than those made with similar prior art fluorescers.

    摘要: An improved method is described for preparing bis(phenylethynyl)anthracenes by reacting a quinone with the lithium salt of phenylacetylene to obtain a dihydro-dihydroxybis(phenylethynyl)anthracene, and converting the latter compound in situ to the corresponding bis(phenylethynyl)-anthracene. The products are useful as fluorescers in chemiluminescent systems.
