Kim, Mingi; Ryu, Chan Hee; You, Dong Kyun; Hong, Ju Hyun; Lee, Kang Mun published an article in 2022. The article was titled 《Crucial Factors Regulating Intramolecular Charge-Transfer-Based Radiative Efficiency in ortho-Carboranyl Luminophores: Planarity between Substituted Biphenyl Rings》, and you may find the article in ACS Omega.Name: 1-Bromo-2-isopropylbenzene The information in the text is summarized as follows:
O-Carboranyl compounds contain specific geometries, ranging from planar to orthogonally distorted biphenyl rings. Herein, 13 o-carboranyl compounds, 1HF-13PP, were synthesized and fully characterized to determine the impact of structural formation of the aromatic group appended with the o-carborane to estimate the efficiency of their radiative decay process. All the compounds exhibited significant intramol. charge transfer (ICT)-based emission in the crystalline state at 298 K. Remarkably, increasing the distorted dihedral angles between biphenyl rings gradually decreased the emission efficiencies. Also, their radiative decay constants decreased linearly with increasing dihedral angles, which demonstrated the inversely proportional relation between these two factors. These findings distinctly suggest that the planar or distorted geometry of substituted aryl groups can strongly affect the efficiency of the ICT-based radiative process in o-carboranyl luminophores.1-Bromo-2-isopropylbenzene(cas: 7073-94-1Name: 1-Bromo-2-isopropylbenzene) was used in this study.
1-Bromo-2-isopropylbenzene(cas: 7073-94-1) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. Alkyl bromides are mainly used as alkylating agents and also find application as a solvent to extract oil from seeds and wool. Name: 1-Bromo-2-isopropylbenzene
