The development of materials with circularly polarized luminescence (CPL) properties is a promising but challenging frontier in advanced science. Modulating the chiral polymers has also been focus research. Studies have conducted to control ground-state chirality by adjusting concentration dopant. However, inversion CPL fluorescent liquid crystal particles dopant not reported. Here, we report preparation cholesteric (FCLC) that display polarizable structural color and CPL, demonstrating how varying amount can reverse direction, leading systems where rotation directions either align or differ. This study confirmed critical role played formation twist grain boundary phase inducing FCLC and, subsequently, triggering process chirality. Furthermore, it leverages fluorescence develop sophisticated dual verification system. system, utilizing both light fluorescence, offers enhanced anticounterfeiting protection for high-value items.

Constructing full-color circularly polarized luminescence (CPL) materials with switchable handedness in the solid state is an appealing yet considerably challenging task, especially for supramolecular polymer films assembled from homochiral monomers. Herein, polymers CPL and inverted are realized through coassembly of a cholesterol derivative (PVPCC), metal ions (Zn2+), achiral fluorescent dyes. The obtained coassembled systems show anion-directed chirality inversion by exchanging anions NO3–, ClO4–, BF4–, Cl–. For instance, negative CD right-handed detected PVPCC/Zn(NO3)2 aggregates, which convert into positive left-handed after introducing Cl–, corresponding to transformation nanorods nanofibers. Furthermore, tunable color system dyes can be established alternately changing assembling temperature 298 273 K. Importantly, polymeric then constructed doping PVPCC/Zn(NO3)2/dyes complexes poly(methyl methacrylate) (PMMA) film, maintains shows enhanced performance. work not only deepens understanding chemistry but also helps construct building blocks science.

Helical structures such as right-handed double helix for DNA and left-handed α-helix proteins in biological systems are inherently chiral. Importantly, chirality at the nanoscopic level plays a vital role their macroscopic chiral functionalities. In order to mimic functions of natural nanoarchitectures, variety nanostructures obtained from artificial helical polymers prepared, which can be directly observed by atomic force microscopy (AFM), scanning tunneling (STM), electron (SEM), transmission (TEM). This review mainly focuses on formation morphology regulation triggered polymer chain length, concentration, solvent, temperature, photoirradiation, chemical additives. addition, distinct including recognition, circularly polarized luminescence, drug release, cell imaging, antibiosis also discussed.
