Description

Technical Field

[0001] The invention relates to the technical field of circularly polarized light materials, and in particular to a triphenylamine supramolecular polymer capable of adjusting circularly polarized light, a preparation method and an application thereof. Background Art

[0002] Practical applications of circularly polarized luminescent (CPL) materials in 3D displays and photonic technologies require broad color tunability covering the entire visible spectrum. Materials containing chiral π-aromatic luminophores are promising candidates to achieve this goal due to their well-defined structures, ease of modification, and ability to control multiscale chirality. Modulating the π-conjugation length of aromatic luminophores is a feasible approach to tune the CPL emission color. Another option is to design D-π-A chiral luminophores with intramolecular charge transfer interactions (ICT), where D and A represent electron donors and acceptors, respectively.

[0059] Example 5

[0060] The preparation method of the triphenylamine supramolecular polymer capable of adjusting circular polarized light proposed by the present invention comprises the following steps: dissolving a triphenylamine donor and a naphthalene monoamide acceptor in methylcyclohexane (MCH) at a molar ratio of 1:1. The concentration of the supramolecular polymer is 40 mg / mL. The mixed solution is spin-coated (1000 r / min, 60 s) on a quartz plate to form a film. Subsequently, the film is heated to 80° C., maintained for 5 minutes, and then cooled to room temperature.

[0061] like Figure 1 As shown, the triphenylamine donor of the present invention forms a one-dimensional supramolecular homopolymer under the promotion of triple hydrogen bonding, and the helical bias of the supramolecular polymer is controlled by the long-range chirality transfer of the alkyl stereocenter on the triphenylamine donor to the internal triphenylamine core, resulting in the appearance of a blue CPL signal; when the triphenylamine donor is mixed with a naphthalene monoamide acceptor, the resulting supramolecular donor-acceptor polymer exhibits green, yellow, orange and red CPL. These color changes are achieved by adjusting the charge transfer intensity by making minor structural modifications to the donor or acceptor unit. It is worth noting that the subtle structural changes to the triphenylamine donor lead to completely different donor-acceptor arrangements at the supramolecular level. Specifically, the triphenylamine donor containing an acetylene connection induces a ground-state charge transfer toward the naphthalene monoamide guest. The triphenylamine donor without an acetylene connection promotes excited-state charge transfer under the same conditions, resulting in differences in luminescence lifetimes.

[0062] like Figure 2 As shown, the (R)-1 supramolecular polymer exhibits a blue CPL signal (λmax: 472 nm, Figure 2a), the equimolar mixture of (R)-1 and compound 3 (Formula 5) resulted in green emission. By changing the structure of the triphenylamine donor or the naphthalene monoimide acceptor to adjust the color of the cyclic polarized emission, the supramolecular homopolymer of (R)-2 showed blue cyclic polarized emission at 453 nm ( Figure 2 b); Mixing compound (R)-2 and compound 3 (Formula 5) will undergo non-covalent donor-acceptor polymerization, generating an orange circularly polarized luminescence signal centered at 558nm (|glum|:5.6×10-3, τ:53.4ns, Figure 2 b).

[0063] In general, triphenylamine donors (R)-1 and (R)-2 emit blue light in the supramolecular homopolymer state. The charge transfer complex between triphenylamine and naphthalene monoimide leads to red-shifted cyclic polarized luminescence, the direction of which depends on the triphenylamine donor. By modifying the acetylene bond on the triphenylamine donor to adjust the HOMO energy level and attaching bromine atoms on the naphthalene monoimide acceptor to change the LUMO energy level, supramolecular donor-acceptor polymers of complexes 1·3, 1·4, 2·3 and 2·4 are provided, which show green, yellow, orange and red cyclic polarized luminescence signals, respectively ( Figure 2 c), wherein compound 1 is of formula 1, compound 2 is of formula 2, compound 3 is of formula 5, and compound 4 is of formula 6.

[0064] The (S)-1 and (S)-2 of the present invention are chiral enantiomers of (R)-1 and (R)-2, respectively, and are used to realize luminescent chiral signals opposite to (R)-1 and (R)-2; for example, the (S)-1 supramolecular polymer emits left-handed circularly polarized light under ultraviolet light excitation; then, the (R)-1 supramolecular polymer emits right-handed circularly polarized light under ultraviolet light excitation.
