摘要：4,4-Difluoro-3,5-bis（3,3-dimethyl-1-butenyl）-8-phenyl-4-bora-3 a,4 a-diaza-s-indacene（1）,a symmetric fluorescent difluoroboron dipyrromethene dye,was produced in Knoevenagel reaction involving 4,4-difluoro-3,5-bis（methyl）-8-anthryl-4-bora-3 a,4 a-diaza-s-indacene（2） and pivaldehyde.Its crystal structure was determined by single crystal X-ray diffraction analysis,and the photophysical properties were investigated.1-3 The BODIPY 1 exhibits significant bathochromic shifts in both absorption and fluorescence spectrum compared with the BODIPY 2.In addition,the BODIPY 1 exhibited small energy gaps（2.11 e V）.The presence of 3,3-dimethyl-1-butenyl substituents affects the absorption and emission maxima of the BODIPY nucleus,thereby confirming that these units are coupled electronically.4-6 The extensive π conjugation is responsible for their red-shifted emission.Cell imaging experiments demonstrated that this dyes represent an important addition to the range of strongly absorbing and emitting reagents that could be used as a candidate for bio-related fluorescent bioimaging.
