Antenna 9-benzyl

Remarkable concentration of the photon energy absorbed by aromatic dendritic scaffold toward the focal point (herein called antenna effects ) is one of the most distinct features of the dendritic macromolecules. Poly(benzyl ether) (PBE) dendron [1] has been studied most extensively as an efficient antenna dendron. Careful studies have revealed the crucial role of the symmetric dendritic structure for the antenna effect. [Pg.194]

Heptakis 6-0-t-butyldimethylsilyl-P-cyclodextrin, on reaction with 4-chloro-methyl-A -methyl-2-nitroaniline, affords the mono-3-substituted benzyl ether. P-Cyclodextrin carrying a 2-(naphthylmethyl) group at 0-6 exists with the aromatic rings within the cavity to an extent which is very temperature dependent. Temperature can therefore be used to control the degree of complexing of the aromatic system with a fluorescent naphthalene compound. Heptakis-[2,3-di-0-acetyl-6-deoxy-6-iodo]-P-cyclodextrin treated with 6-methoxycarbonyl-2-naphthol allowed access to the compound having naphthoic acid substituents at all of the primary positions, and this forms a very stable 1 1 complex with a merocyanine laser dye which is a mimic of the antenna function in photosynthesis and shows promise as a photochemical microreactor. Mono-[6-0-(8-qui-nolyl)]-P-cyclodextrin has been reported, and the stabilities of inclusion complexes with amino acid guests have been described. ... [Pg.79]

However, the components of the pheromone of a butterfly are known to give different amplitude EAG s (359). Grant (360) found that pheromones from different species elicit EAG s of similar amplitude in a common recipient. EAG s of similar amplitude were obtained when the antenna of the armyworm, Pseudaletia unipunctata, was stimulated with the male s known pheromone components, benzaldehyde, benzyl alcohol and benzoic acid, or with the related aromatic compounds, 2-phenyl-ethanol and benzyl acetate (361). The antennal response of male European corn borer moths, Ostrinia nubilalis, to their two pheromone components, (Z)- and ( )-ll-tetradecenyl acetates has recently shown that repetitive stimulation with one of the isomers results in adaptation which affects the amplitude of response in subsequent tests to both compounds (362). [Pg.101]
