Organic Polymer-Constructed Chiral Particles: Preparation and Chiral Applications

Optically active polymer particles with programmable surface microstructures constructed using chiral helical polyacetylene

“…[54][55][56][57][58] Notably, the CD and UVvis spectra used to analyze the particles are considered being qualitative. However, according to the spectra and referring to our reported work concerning chiral helical polymers in the forms of solution, particles, fibers, and gels, 54,[56][57][58][59][60] we can conclude that R-JPs and S-JPs were grafted with substituted polyacetylenes adopting predominantly a one-handed helical conformation, and therefore the composite particles exhibited remarkable Cotton effects and optical activity.…”

Application of molecularly imprinted polymers (MIPs) as environmental separation tools

“…7 The distinguishing feature of molecular recognition lies in its ability to specifically target particular molecules. 8,9 Biomedical applications heavily rely on this principle 10. However, there are certain limitations 10 such as limited lifespan, instability under extreme conditions, increased costs, and challenging adaptation to a large-scale level.…”

Circularly Polarized Fluorescence Energy Transfer for Constructing Multicolor Circularly Polarized Luminescence Films with Controllable Handedness

“…Nonetheless, the above helical structural feature poses a great challenge for developing biomimetic light-harvesting materials due to the formidable challenge in design and especially precisely constructing artificial helical architectures . In preceding studies, we have developed a series of chiral helical polyacetylenes and advanced chiroptical materials thereof with preferred handedness. − In the aforementioned context, we make efforts to explore bioinspired chiroptical films derived from chiral helical polymer and achiral fluorophores, which interestingly show the anticipated circularly polarized luminescence (CPL) property, taking advantage of circularly polarized fluorescence energy transfer strategy, as reported in this contribution. Also worth highlighting is that in comparison with other CPL counterparts, solid films are considered to be incomparably advantageous from the perspective of practical uses …”
