Cyanine Borate Salts that Form Penetrated Ion Pairs in Benzene Solution: Synthesis, Properties, and Structure was written by Murphy, Sean;Yang, Xiquiang;Schuster, Gary B.. And the article was included in Journal of Organic Chemistry in 1995.Reference of 162258-89-1 This article mentions the following:

A series of cyanine borate salts were prepared and studied by laser spectroscopy, fluorescence spectroscopy, NMR spectral methods, and computer modeling. Anal. of the chem., phys., and spectral properties of these salts shows that, in benzene solution, they form penetrated ion pairs. The center-to-center distance between the ions is less than the sum of the individual ionic radii. We call such structures penetrated ion pairs. Penetration affects the properties of the cyanine dyes in unique ways that are described. In the experiment, the researchers used many compounds, for example, 4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1Reference of 162258-89-1).

4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.

Intramolecular Charge-Transfer Interaction in a New Dyad Based on C₆₀ and Bis(4′-tert-butylbiphenyl-4-yl)aniline (BBA) Donor was written by Ohno, Toshinobu;Moriwaki, Kazuyuki;Miyata, Toshiyuki. And the article was included in Journal of Organic Chemistry in 2001.Synthetic Route of C16H17Br This article mentions the following:

A novel methanofullerene dyad based on C₆₀ and bis(4′-tert-butylbiphenyl-4-yl)aniline (BBA) has been prepared and characterized. Cyclic voltammetry (CV) and UV-vis spectra of the C₆₀-BBA methanofullerene dyad, 61-phenyl-1,2-methanofullerene[60], 1,2-methanofullerene[60], and BBA were measured and analyzed. CV measurements showed that a reversible oxidation wave of the C₆₀-BBA methanofullerene dyad was pos. shifted by 40 mV compared to that of BBA. More remarkably, comparing UV-vis spectra of the C₆₀-BBA methanofullerene dyad and 1,2-methanofullerene[60] shows a large increase in intensity for a broad band at 500 nm in the dyad despite the lack of an absorbance at >400 nm for BBA. These results indicate the presence of charge-transfer interactions in the C₆₀-BBA methanofullerene dyad between the fullerene moiety and diarylaniline moieties. In the experiment, the researchers used many compounds, for example, 4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1Synthetic Route of C16H17Br).

4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.Synthetic Route of C16H17Br

Rational design of perfectly oriented thermally activated delayed fluorescence emitter for efficient red electroluminescence was written by Zeng, Xuan;Huang, Yu-Hsin;Gong, Shaolong;Yin, Xuguang;Lee, Wei-Kai;Xiao, Xiao;Zhang, Yu;Zeng, Weixuan;Lu, Chen-Han;Lee, Chang-Cheng;Dong, Xiu-Qin;Zhong, Cheng;Wu, Chung-Chih;Yang, Chuluo. And the article was included in Science China Materials in 2021.Formula: C16H17Br This article mentions the following:

How to control the dipole orientation of organic emitters is a challenge in the field of organic light-emitting diodes (OLEDs). Herein, a linear thermally activated delayed fluorescence (TADF) mol., PhNAI-PMSBA, bearing a 1,8-naphthalimide-acridine framework was designed by a double-site long-axis extension strategy to actively control the dipole orientation. The horizontal ratio of emitting dipole orientation of PhNAI-PMSBA reaches 95%, substantially higher than that of isotropic emitters (67%). This unique feature is associated with the intrinsically horizontal mol. orientation of PhNAI-PMSBA and the good agreement between its transition dipole moment direction and mol. long axis. The PhNAI-PMSBA-based OLED achieves an ultrahigh optical outcoupling efficiency of 43.2% and thus affords one of the highest red electroluminescence with an external quantum efficiency of 22.3% and the Commission International de l′Eclairage 1931 coordinates at around (0.60, 0.40). In the experiment, the researchers used many compounds, for example, 4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1Formula: C16H17Br).
