solvatochromic fluorescence (>190 nm emission shift in polar media), which was derived from intramolecular charge transfer (ICT) character that revealed by DFT/TD-DFT calculation. And largeStokesshifts (210–306 nm) were observed in different organic solvents, along with rich color changes from blue to green, yellow, orange and even purple-red. The Stokesshifts were linearly dependent on the solvent polarity

fluorene unit next to the fluorenone ring or increasing the number of thienyl ring next to the cyanoacrylic acid group, which is consistent with the results from electrochemical impedance spectroscopy. The maximal monochromatic incident photon-to-current conversion efficiency (IPCE) can reach up to 80% for DSSC devices based on F4 with the overall light to electricity conversion efficiency up to 4.71%
四种新的有机染料(F1 - F4)合成了三芳基胺或芴单元作为供电子基团,在分子骨架中较少使用的芴酮间隔基和氰基丙烯酸作为锚定基团,进行了表征,并用于染料敏化太阳能电池(DSSC)中。对它们的吸收,光致发光,电化学和光伏特性进行了详细研究。电化学数据表明,HOMO和LUMO能级的调节可以方便地通过交替供体部分来完成。可以通过在芴酮环旁添加给电子三芳基胺或芴单元或在氰基丙烯酸基团旁增加噻吩基环的数量来提高光伏性能,这与电化学阻抗谱的结果一致。F4 在AM 1.5辐照(100 mW cm -2)下具有高达4.71%的总光电转换效率(V oc = 565 mV,J sc = 11.71 mA cm -2和FF = 0.71 )。
