Determination of organic colorants in cosmetic products by high-performance liquid chromatography

Summary High-performance liquid chromatography (HPLC) with UV-vis detection was used for the determination of organic colorants in cosmetic products. 126 colorants were characterized by their retention times in an ion-pair reversed-phase HPLC system with gradient elution, and by their UV-vis spectra, recorded with a diode array detector (DAD). The method is rapid and efficient, as is demonstrated by the analysis of 45 cosmetic samples.

Synthesis of N,N,N′,N′-tetrasubstituted 1,3-bis(4-aminophenyl)azulenes and their application to a hole-injecting material in organic electroluminescent devices

After a preliminary search of the reaction conditions for the Suzuki-Miyaura cross-coupling of haloazulenes with arylboronic acids, the title compounds were synthesized either by the direct coupling reaction between 1,3-dihaloazulene and the corresponding N,N-disubstituted 4-aminophenylboronic acids or by a two-step sequence involving the cross-coupling with 4-bromophenylboronic acid and subsequent Pd-catalyzed amination. Application of the title diamines to a hole-injecting material in organic electroluminescent devices was carried out to provide their prominent characteristics as a novel durable, non-cyanine and non-polyamine substance without color fade. The diamine derivatives, extended by an ethynyl unit between the azulenyl core and the 4-aminophenyl moiety, were also synthesized and found, unfortunately, unsuitable for vacuum deposition in preparing a multilayer composite.

Electroplex emission from a blend of poly(N-vinylcarbazole) and 2,9-dimethyl-4,7-diphenyl-1, 10-phenanthroline

The PL and EL spectra of poly(N-vinylcarbazole) (PVK) : 2,9-dimethyl-4,7-diphenyl-1, 10-phenanthroline (BCP) (1:1 w/w) film were found completely different. The PL spectrum is a single peak at 415 nm that originates from excitons emission from PVK, and the tail of the spectrum is suggested to be excimer emission from BCP molecules. However, a new emission at 595 nm was found in the EL spectra of devices ITO/PEDOT:PSS(50 nm)/PVK:BCP(1:1)(100 nm)/Al. After aggregate, exciplex and product of electrochemical reaction were ruled out, the new emission was proposed to be electroplex emission that occurred between PVK and BCP molecules. Under high voltage, only electroplex emission can be observed in the EL spectra.     

(聚苯乙烯/有机蒙脱土)/聚丙烯酸正丁酯核壳纳米复合材料的制备

采用半连续种子乳液聚合方法,制备了以聚苯乙烯(PSt)/有机蒙脱土(OMMT)为核,聚丙烯酸正丁酯(PBA)为壳的核壳纳米复合材料(CSN)。借助傅里叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)考察了CSN的粒子结构及形貌,显示CSN呈球形,核壳结构明显。通过种子用量、核壳质量配比、引发剂用量及单体总量对乳液性能的研究,结果表明,当种子用量为20%,核壳质量配比2∶1,引发剂用量0.6%(wt),单体总量45%(wt)时,乳液的固含量、转化率较高,耐水性、化学稳定性及机械稳定性较好。热重分析(TGA)表明CSN复合材料热稳定性有所提高。
