| contents | Effect of the naphthylene linker on the J ‐aggregation abilities of chlorophyll‐ a derivatives Yuma Hisahara Takeo Nakano Hitoshi Tamiaki Photochemistry and Photobiology Abstract Chlorophyll(Chl)‐ a derivatives inserting an ethynylene‐naphthylene linker between the chlorin π‐skeleton and hydroxymethyl group were prepared as models of chlorosomal Chls. Their syntheses were achieved via Sonogashira coupling reaction. Their J ‐aggregation behaviors were investigated by electronic absorption and circular dichroism spectroscopic measurements. These studies revealed that the 2,6‐naphthylene inserted Chl‐ a derivatives gave the single J ‐aggregation species in an aqueous Triton X‐100 micellar solution with a larger red‐shift value (1270 cm −1 ) of the Qy band in spite of its longer linker compared with p ‐phenylene inserted Chl‐ a derivative (970 cm −1 ). These unique optical properties were also discussed based on the computational studies, which indicated the different positional relation of chlorin rings in the assemblies by the linker structure. 10.1111/php.14076 http://creativecommons.org/licenses/by/4.0/ |
