“…Chirality and its expression through circular dichroism (CD) are also properties that can be linked to aggregate structure. [125][126][127] Tetraphenylethylene (TPE) is one of the most studied AIEgens and its isolated molecules are achiral because of the free rotation of the four phenyl rings, as reflected by the silent CD signal of its solution. [128][129][130] However, in 2011, Zhang et al observed a pair of inverse CD spectra from two TPE crystals ( Figure 5).…”

Molecular science entails the study of structures and properties of materials at the level of single molecules or small interacting complexes of molecules. Moving beyond single molecules and well‐defined complexes, aggregates (i.e., irregular clusters of many molecules) serve as a particularly useful form of materials that often display modified or wholly new properties compared to their molecular components. Some unique structures and phenomena such as polymorphic aggregates, aggregation‐induced symmetry breaking, and cluster excitons are only identified in aggregates, as a few examples of their exotic features. Here, by virtue of the flourishing research on aggregation‐induced emission, the concept of “aggregate science” is put forward to fill the gaps between molecules and aggregates. Structures and properties on the aggregate scale are also systematically summarized. The structure–property relationships established for aggregates are expected to contribute to new materials and technological development. Ultimately, aggregate science may become an interdisciplinary research field and serves as a general platform for academic research.

Chiral supramolecules have great potential for use in chiral recognition, sensing, and catalysis. Particularly, chiral supramolecular biocoordination polymers (SBCPs) provide a versatile platform for characterizing biorelated processes such as chirality transcription. Here, we selectively synthesize homochiral and heterochiral SBCPs, composed of chiral naphthalene diimide ligands and Zn ions, from enantiomeric and mixed R-ligands and S-ligands, respectively. Notably, we find that the chiral self-sorted SBCPs exhibit multifunctional properties, including photochromic, photoluminescent, photoconductive, and chemiresistive characteristics, thus can be used for various sensors. Specifically, these materials can be used for detecting hazardous amine materials due to the electron transfer from the amine to the SBCP surface and for enantioselectively sensing a chiral species naproxen due to the different binding energies with regard to their chirality. These results provide guidelines for the synthesis of chiral SBCPs and demonstrate their versatility and feasibility for use in various sensors covering photoactive, chemiresistive, and chiral sensors.

“…Organic p-conjugated materials have received much attention due to their tunable optical and electrical properties, suitability for exible device fabrication, and large-area processability. [1][2][3] Organic eld-effect transistors (OFETs), 4,5 organic light-emitting diodes (OLEDs), 6 organic phototransistors (OPTs), [7][8][9] organic photovoltaics (OPVs), 10,11 organic memories, 12 and organic sensors 13 have been successfully developed. Phototransistors, which allow one to control channel conductance via light absorption, are particularly applicable to electronic devices such as light sensors and optical switches.…”
