Fluorenyl-diformyl phenol Schiff (HL) base is spectroscopically characterized and demonstrates aggregation induced emission enhancement (AIEE) upon addition of water to THE solution. Maximum intensity is observed at 90% of water addition at 570 nm. Al3+ induced turn-on fluorescence enhancement is observed at 600 nm and the limit of optical detection (LOD) is 6.22x10(-9) M. Isolation of Al(III)-complex and mass spectral measurement shows the formation of phenoxo-bridged dinuclear complex. Applicability for DSSC device fabrication of probe shows photovoltaic efficiency 0.021%. DFT computation of optimized geometry of HL has been used to explain the spectral and photovoltaic activity.
