Barbituric Derivative Nanoaggregates with Aggregation-Induced Emission and Mechanofluorochromism

Barbituric Derivative Nanoaggregates with Aggregation-Induced Emission and Mechanofluorochromism

Three new nonplanar barbituric derivatives, named as TTB, TTTB, and TOB, were synthesized. The D-π-A type conjugated compounds showed obvious intramolecular charge transfer (ICT) property, which was evidenced by theoretical calculations and spectral analyses. All of them exhibited aggregation induce...
