to pristine C60. Neat thin films of the n‐decyl compound 1 a demonstrated electron mobility of (1.3±0.4)×10−3 cm2 V−1 s−1, which was comparable to phenyl‐C61‐butyric acidmethylester (PCBM) and thus potentially advantageous for organic solar cells (OSC). Application of 1 in OSC allowed a twofold increase in the power conversion efficiencies of as‐cast poly(3‐hexylthiophene‐2,5‐diyl) (P3HT)/1 devices
通过锂盐辅助的[2 + 3]环加成反应,制备了一系列新型的高可溶性双笼[60]富勒烯衍生物。双球分子具有通过四元循环和具有酯官能团CO 2 R(R =正癸基,正十八烷基,苄基和正丁基;化合物 1 a – d,分别由NMR光谱和X射线衍射证明。循环伏安法研究表明,由于富勒烯笼的连续单电子还原,三对可逆峰紧密重叠,以及归因于从氮孤电子对中提取电子的不可逆氧化峰。由于两个碳笼上的电荷离域,化合物 1 a – d的特征是前沿分子轨道的能量上移,带隙变窄以及相对于原始C 60降低的电子转移重组能。正癸基化合物 1a的整洁薄膜显示出(1.3±0.4)×10 -3 cm的电子迁移率2 V -1 s -1,与苯基-C 61-丁酸甲酯(PCBM)相当,因此对于有机太阳能电池(OSC)可能具有优势。在OSC中应用1可使铸造的聚(3-己基噻吩-2,5-二基)(P3HT)/ 1器件的功率转换效率相对于铸造的P3HT

A proteinous emulsifier is obtained by reacting an amino acid ester with a hydrophilic protein in the presence of endopeptidase to bind the amino group of the amino acid ester to the carboxyl terminal of a hydrophilic protein decomposition product through an amide bond. This emulsifier has a typical surfactant structure wherein the hydrophobic amino acid ester moiety is bound to the end of the hydrophilic protein moiety. It slightly stimulates skin and shows a strong emulsifying effect and a good moisture retention, thus being extremely suitable as emulsifier for various cosmetic preparations such as creams, milky lotions, etc.
