    Abstract: 摘要 我們以七環十四碳烷(HCTD)為架橋分子(Bridge),利用了Wittig Rection與Knoevenagel condensation反應,成功的合成出了一系列具有電子予體(Donor)與電子受體(Acceptor)的分子化合物15、16、17以及25、26、27與35、36、37。 在這一系列的Donor-Bridge-Acceptor(D-B-A)分子化合物中,我們從螢光光譜中可以看出,光誘導電子轉移的機制,在化合物15、化合物16與化合物25、化合物26中進行著,而在化合物35與化合物36中,則沒有發現。 Syntheses and Properties of Heptcyclo[]tetradecane derivatives containing electron Donor and Acceptor Substituents Jen-Chi Yu, Tahsin J. Chow* Institute of Chemistry, Academia Sinica, Taipei, Taiwan, 115 Starting from Heptcyclo[]tetradecane, we were able to synthesize donor-bridge-acceptor substituted derivatives by condensation reaction. The components for the condensations were malonitrile and ethyl cyanoacetate for the acceptor part, and benzyltriphenylphosphate (7), [(naphthalene-1-yl)methyl]- triphenylphosphate (8), and[(anthracen-9-yl)methyl]triphenylphosphate (9). To condense malonitrile and ethyl cyanoacetate we used the Knoevenagel condensation and for the phosphates we used the Wittig reaction procedure. Fluorescence spectra provided evidence for efficient photoinduce electron transfer in only the benzene and naphthalene derivatives, but not in the analogous anthracene derivative.
