Innovation Inspired by Classical Chemistry: Luminescent Hyperbranched Polysiloxanes

Revised Date: 7 November 2024

As a special class of unconventional aggregation-induced emission (AIE) polymers, hyperbranched polysiloxanes have attracted much attention in luminescent materials due to their distinctive structure, excellent properties, and diverse applications. In this paper, starting from the incidental discovery of the luminescent properties of hyperbranched polysiloxanes with Si―O―C backbone structure, we innovatively developed the ‘transesterification polycondensation method’ inspired by the principle of classical esterification reaction. Through molecular design and structural modulation, the multicolor fluorescence emission from blue to red, high quantum yield and long fluorescence lifetime of hyperbranched polysiloxanes have been achieved. These materials also demonstrate practical applications in ion detection, information encryption, and reactive oxygen species (ROS) scavenging. Building on these breakthroughs, we present the concept of “Innovation Inspired by Classics” to cultivate students' dialectical thinking and innovative capabilities, while incorporating ideological and political elements into chemistry education.
