In 2022,Zhang, Jianyu; Alam, Parvej; Zhang, Siwei; Shen, Hanchen; Hu, Lianrui; Sung, Herman H. Y.; Williams, Ian D.; Sun, Jianwei; Lam, Jacky W. Y.; Zhang, Haoke; Tang, Ben Zhong published an article in Nature Communications. The title of the article was 《Secondary through-space interactions facilitated single-molecule white-light emission from clusteroluminogens》.Recommanded Product: 4-Iodobenzaldehyde The author mentioned the following in the article:
Clusteroluminogens refer to some non-conjugated mols. that show visible light and unique electronic properties with through-space interactions due to the formation of aggregates. Although mature and systematic theories of mol. photophysics have been developed to study conventional conjugated chromophores, it is still challenging to endow clusteroluminogens with designed photophys. properties by manipulating through-space interactions. Herein, three clusteroluminogens with non-conjugated donor-acceptor structures and different halide substituents are designed and synthesized. These compounds show multiple emissions and even single-mol. white-light emission in the crystalline state. The intensity ratio of these emissions is easily manipulated by changing the halide atom and excitation wavelength. Exptl. and theor. results successfully disclose the electronic nature of these multiple emissions: through-space conjugation for short-wavelength fluorescence, through-space charge transfer based on secondary through-space interactions for long-wavelength fluorescence, and room-temperature phosphorescence. The introduction of secondary through-space interactions to clusteroluminogens not only enriches their varieties of photophys. properties but also inspires the establishment of novel aggregate photophysics for clusteroluminescence. The results came from multiple reactions, including the reaction of 4-Iodobenzaldehyde(cas: 15164-44-0Recommanded Product: 4-Iodobenzaldehyde)
