摘要:
New optically active dendrimers (1-3) containing rigid and cross-conjugated units have been synthesized and characterized. UV and fluorescence spectroscopic studies demonstrate that the energy harvested by the periphery of the dendrimers can be efficiently transferred to the core. The fluorescence of the dendrimers can be quenched by amino alcohols (4-6) both efficiently and enantioselectively. The energy migration and light harvesting effects of the dendrimers make the higher generation dendrimers more sensitive fluorescent quencher than the lower ones.
