Kay, Kwang-Yol published the artcileSynthesis and electroluminescent properties of fluorene- and anthracene-derivatives containing novel tetraphenylbenzene moiety, COA of Formula: C18H10, the publication is Molecular Crystals and Liquid Crystals (2004), 167-172, database is CAplus.

2,7-Bis[(2,3,4,5-tetraphenyl)phenyl]-9,9-diethylfluorene (BTPDF) and 2,7-bis[(2,3,4,5-tetraphenyl)phenyl]-9,10-anthracene (BTPA), which consist of a diethylfluorene and an anthracene with two tetraphenylbenzene moieties, were synthesized by Diels-Alder reaction and characterized to investigate electroluminescent (EL) behavior. BTPDF and BTPA showed violet and blue photoluminescence spectra at 400 nm and 456 nm. The device of m-MTDATA (600 脜)/NPB (150 脜)/BTPDF or BTPA (300 脜)/Alq3 (300 脜)/LiF (10 脜)/Al (2000 脜) showed turn-on voltage of 9 V and 13 V and blue and green EL spectrum at 466 nm and 504 nm, resp.

Sagara, Yoshimitsu published the artcileBrightly Tricolored Mechanochromic Luminescence from a Single-Luminophore Liquid Crystal: Reversible Writing and Erasing of Images, Application In Synthesis of 18512-55-5, the publication is Angewandte Chemie, International Edition (2011), 50(39), 9128-9132, S9128/1-S9128/20, database is CAplus and MEDLINE.

The authors report a new type of stimuli-responsive luminescent liquid crystal that exhibits three luminescent colors, which can be switched by mech. and thermal stimuli. The liquid crystal is composed of equimolar amounts of the dumbbell-shaped compound I and compound II. The three luminescent colors observed are reddish-orange, yellow, and green, which are easily distinguished by the naked eye. Moreover, the liquid crystal mixture of I and II contains only one type of luminophor, 9,10-bis(phenylethynyl)anthracene and no additives are required to induce the luminescent color changes. The present results reveal that materials containing only a single luminophor component can switch between three different luminescent colors in the condensed state depending upon the molecularly assembled structures. Moreover, these luminescent images are capable of being written and erased. If a single luminophor component is sufficient to achieve a multiluminescent color device, it can lead to cost reduction in the production of multicolor luminescent displays and sophisticated stimuli-responsive luminescent materials. The authors results also imply that the switching of assembled structures of luminescent groups is one of the most promising ways to obtain external-stimuli-responsive luminescent materials, which adds to the conventional approaches of inducing change to the mol. structures itself by light, pH, redox, and mech. stimuli.

Singh, Jatinder published the artcileSelective and quantitative synthesis of a linear [3]catenane by two component coordination-driven self-assembly, Category: naphthyridine, the publication is Chemical Communications (Cambridge, United Kingdom) (2019), 55(48), 6866-6869, database is CAplus and MEDLINE.

Here we report the synthesis of a linear [3]catenane comprised of three interlocking rings, by coordination-driven self-assembly. Naphthalene-based acceptor A1 and triazole-based donor L1 were utilized for the self-assembly reaction, which facilitated the formation of linear [3]catenane topol. through synergistic non-covalent intercycler interactions (π-π, CH-π and CH-N).
