monomer transfer

For AB_1 and AB_18, their UV-visible absorption spectra in cyclohexane and surface photovoltage spectra show peaks at 450 nm due to the formation of H-aggregate, which underwent a blue-shift about 30 nm than that of monomer intramolecular charge transfer ( ICT) band in chloroform.

AB18在环己烷中聚集体的吸收光谱及AB1和AB18的表面光电压谱在450nm附近出现H聚集体的谱带，比其在氯仿溶液中单体的ICT带蓝移了30nm左右。

Its fluorescence spectrum shows distinct solvent, concentration and temperature effects. Under different experimental conditions, the fluorescence may emit from pyrenyl monomer, intramolecular charge transfer complex ( Intra CT) and intermolecular charge transfer complex ( Inter CT).

其荧光光谱表现出明显的溶剂极性效应、浓度效应和温度效应，不同的环境条件下可发射芘单体的荧光、分子内电荷转移络合物的荧光及分子间电荷转移络合物的荧光。
