In the field of fluorescent materials, bright deep-red/near-infrared (DR/NIR) luminogens are always in demand whose rationally and accurately design yet are challenging. Current design strategy of DR/NIR emitters mainly depends on the construction of large p-conjugation and strong donor-acceptor system, which commonly suffers the quenching factors from p-p stacking and twisted intramolecular charge transfer (TICT) effect. In this work, we employed the non-covalent interactions and constructed a luminogen with rigid and twisted conformation, which not only red-shifts the emission wavelength of the luminogen to DR/NIR region but also effectively suppresses the non-radiative decay by p-p stacking and TICT. Moreover, the rational molecular design endows the new luminogen with two-photo absorption capability and superior selectivity towards lipid droplets in different levels including living cells, tissues, and live fish embryo. This work thus presents an elegant, facile and efficient strategy for generating functional DR/NIR emitters.

Covalent Interactions

Non-covalent interactions play an essential role in the folding and self-assembly of large biological assemblies. These interactions are not only a driving force for the formation of large structures but also control conformation and com-plementary shapes of subcomponents that promote the diversity of structures and functions of the resulting assemblies. Understanding how non-covalent interactions direct self-assembly and the effect of conformation and complementary shapes on self-assembled structures will help design artificial supramolecular systems with extended components and functions. Herein, we develop a strategy for controlling more complex self-assembly with lower symmetry and flexible building blocks that combine endohedral non-covalent interactions with a dual curvature in the ligand backbone to give additional shape complementarity. A Diels-Alder reaction was used to break the symmetry of the diazaanthracene units of the ligands to give dual curvature ligands with different shapes and endohedral groups (L1-L3). The self-assembly studies of these ligands demonstrated that non-covalent interactions and shape complementary effectively control the self-assembly and enable the design of cages for supramolecular catalysis.

: Single-crystal X-ray diffraction analysis, nuclear magnetic resonance (NMR), and other characterization methods are used to characterize the complexes formed by cyclopentano-cucurbit[6]uril (abbreviated as CyP6Q[6]) as a host interacting with p-aminobenzenesulfonamide (G1), 4,4'-diaminobiphenyl (G2), and (E)-4,4'-diamino-1,2-diphenylethene (G3) as guests, respectively. The experimental results show that these three aromatic amine molecules have the same interaction mode with CyP6Q[6], interacting with its negatively electric potential portals. The supramolecular interactions include non-covalent interactions of hydrogen bonding and ion-dipole between host and guest molecules. CdCl2 acts as a structureinducing agent to form self-assemblies of multi-dimensional and multi-level supramolecular frameworks that may have potential applications in various functional materials.
