摘要:本研究设计并合成了具有分子内供体ïââ受体结构的新型推拉烷氧基包裹锌卟啉染料,用于染料敏化太阳能电池(dsc).基于噻吩或 2,3-二氢噻吩并[3,4-B][1,4]二恶烷与氰基乙酸的连接体可以将卟啉的光谱响应扩大到近红外区域(§¼850 Nm),这主要归功于氰基乙酸基团.然而,以氰基丙烯酸作为锚定基团的卟啉会导致染料敏化异质结界面的电荷重组速度加快,从而降低器件的光伏性能.通过使用具有 5-乙炔基噻吩-2-羧酸刚性ï-连接体特征结构的卟啉,可以获得功率转换效率为 9.5% 的高效 Dsc 器件.通过光谱,电化学,光电压瞬态衰减和阻抗测量,揭示了ï-共轭连接体和锚定基团对 Dsc 中卟啉染料光电特性的影响.

摘要:The invention generally relates to compounds of the formula I, which are in equilibrium with their 4-hydroxy tautomers, and their pharmaceutically acceptable salts: where n is 0 to 2; A is S, CH2, O, NH or Se, and when n is 0, A is not CH2, and when n is 1, A is not CH2 or NH; X is a substituted or unsubstituted C1-C3 alkyl, C2-C3 alkenyl, C2-C3 alkynyl or amino, or sulfur or oxygen; Ar is a substituted or unsubstituted monocyclic carbocycle or heterocycle, or fused or nonfused polycyclic carbocycle or heterocycle; and R1 and R2 are hydrogen or a moiety that forms together with the attached CO2 a readily hydrolyzable ester group. These compounds and their salts are useful as inhibitors of GARFT or as antiproliferative agents. The invention also pertains to pharmaceutical compositions and methods employing such compounds as GARFT inhibitors or antiproliferative agents. The invention also relates to compounds useful as intermediates for preparing such compounds, and to their synthesis.
