Developing purely organic room-temperature phosphorescence (RTP) materials with high phosphorescence efficiency in film states is important for their applications but remains a great challenge. Herein, a donor-acceptor type RTP mol. (SeX-CzPh) with 9H-selenoxanthen-9-one and 9-phenyl-9H-carbazole as the acceptor and donor units, resp., is designed and synthesized. SeX-CzPh shows a high phosphorescence quantum yield of 44.3% in a doped polystyrene film at room temperature, which is 4-fold higher than that of its analog TX-CzPh with 9H-thioxanthene-9-one as the acceptor unit. The heavy selenium atom plays a key role in achieving high phosphorescence quantum yields, owing to the effective ISC process through strong spin-orbit coupling. Moreover, the SeX-CzPh-based oxygen film sensor exhibits a wide detection range (0-2.1 x 105 ppm), a high KSV (1.27 x 10-4 ppm-1) and a low detection limit (4.9 ppm). This work demonstrates that 9H-selenoxanthen-9-one is a promising building block for the rational design of highly efficient purely organic RTP materials. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride
