  Synthesis of 2,3-diiodoindenes and their applications in construction of 13H-indeno[1,2-l]phenanthrenes

  摘要：

  A series of 2,3-diiodoindene were synthesized at first, and 13H-indeno[1,2-l]phenanthrenes were then constructed via a Suzuki coupling reaction and subsequently a Scholl reaction. Structures of synthesized compounds were fully characterized by H-1 NMR, C-13 NMR, and HRMS. Their photophysical properties, such as UV-vis and FL spectra were investigated, and electronic properties were theoretically calculated by the software of Gaussian 03. The results suggested that these modified indene and indenophenanthrene compounds might have potential applications as light emitting materials. (C) 2012 Elsevier Ltd. All rights reserved.

  photonic devices. To obtain photochromic materials (e.g., diarylethenes) with desired properties, the way to tune energy processes of the excited state is essentially important, from both fundamental and practical viewpoints. The modified diarylethenes mostly focused on structural improvements to achieve efficient photochromism. We report here two new spiro-conjugated indenodiarylethenes (named, SFI-Th and

  光操作的激发态光化学反应和由此产生的光致变色材料因其在分子电子和光子器件中的潜在技术应用而受到广泛关注。为了获得具有所需特性的光致变色材料（例如二芳基乙烯），从基础和实际角度来看，调节激发态能量过程的方法至关重要。改性二芳基乙烯主要集中在结构改进以实现有效的光致变色。我们在这里报告了两种新的螺共轭茚二芳基乙烯（命名为 SFI-Th 和 SFI-Sul），具有正交排列的螺 π-支架。螺芴空间限制了光活性侧芳环的自由体积，而螺共轭指向激发态能量衰减通道的调制，从而允许调整光致变色性能。这些螺二芳基乙烯 SFI-Th 和 SFI-Sul 易于以低成本获得，并显示出独特的光致变色和光致发光特性。一方面，带有双噻吩基侧环的 SFI-Th 是一种出色的光致变色开关，在溶液和无定形状态下均表现出高热稳定性和高抗疲劳性，这可能得益于空间诱导激发态能量转移到可逆光化学反应中，这是由于到两个分子半部之间更高的
